MFC r311569, r311657, and r311949.
r311569: Fix comment in t4_tom. No functional change.
r311657: cxgbe/t4_tom: Fix tid accounting. An offloaded IPv6 connection uses 2 tids, not 1, in the hardware.
r311949: cxgbe/tom: Add VIMAGE support to the TOE driver.
Active Open: - Save the socket's vnet at the time of the active open (t4_connect) and switch to it when processing the reply (do_act_open_rpl or do_act_establish).
Passive Open: - Save the listening socket's vnet in the driver's listen_ctx and switch to it when processing incoming SYNs for the socket. - Reject SYNs that arrive on an ifnet that's not in the same vnet as the listening socket.
CLIP (Compressed Local IPv6) table: - Add only those IPv6 addresses to the CLIP that are in a vnet associated with one of the card's ifnets.
Misc: - Set vnet from the toepcb when processing TCP state transitions. - The kernel sets the vnet when calling the driver's output routine so t4_push_frames runs in proper vnet context already. One exception is when incoming credits trigger tx within the driver's ithread. Set the vnet explicitly in do_fw4_ack for that case.

305695: cxgbe(4): Set up fl_starve_threshold2 accurately for T6.
305696: cxgbe(4): Use correct macro for header length with T6 ASICs. This affects the transmit of the VF driver only.
305699: cxgbe(4): Update the pad_boundary calculation for T6, which has a different range of boundaries.
305702: cxgbe(4): Use smaller min/max bursts for fl descriptors with a T6.
305703: cxgbe(4): Deal with the slightly different SGE_STAT_CFG in T6.
305713: cxgbe(4): Add support for additional port types and link speeds.
305715: cxgbe(4): Catch up with the rename of tlscaps -> cryptocaps. TLS is one of the capabilities of the crypto engine in T6.
305827: cxgbe(4): Use the interface's viid to calculate the PF/VF/VFValid fields to use in tx work requests.
305852: cxgbe(4): Attach to cards with the Terminator 6 ASIC. T6 cards will come up as 't6nex' nexus devices with 'cc' ports hanging off them.
The T6 firmware and configuration files will be added as soon as they are released. For now the driver will try to work with whatever firmware and configuration is on the card's flash.
305906: cxgbe/t4_tom: The SMAC entry for a VI is at a different location in the T6.
305908: cxgbe/t4_tom: Update the active/passive open code to support T6. Data path works as-is.
306062: cxgbe(4): Show wcwr_stats for T6 cards.
306063: cxgbe(4): Setup congestion response for T6 rx queues.
306137: cxgbetool: Add T6 support to the SGE context decoder.
306138: Fix typo.
306206: cxgbe(4): Catch up with the different layout of WHOAMI in T6.
Note that the code moved below t4_prep_adapter() as part of this change because now it needs a working chip_id().
306216: cxgbe(4): Fix the output of the "tids" sysctl on T6.
306273: cxgbe(4): Fix netmap with T6, which doesn't encapsulate SGE_EGR_UPDATE message inside a FW_MSG. The base NIC already deals with updates in either form.
306295: cxgbe(4): Support SIOGIFXMEDIA so that ifconfig displays correct media for 25Gbps and 100Gbps ports. This should have been part of r305713, which is when the driver first started reporting extended media types.
306301: cxgbe(4): Use the port's top speed to figure out whether it is "high speed" or not (for the purpose of calculating the number of queues etc.) This does the right thing for 25Gbps and 100Gbps ports.
306465: cxgbe(4): Claim the T6 -DBG card.
309302: cxgbe(4): Include firmware for T6 cards in the driver. Update all firmwares to 1.16.12.0.

MFC 302339: cxgbe(4): Changes to the CPL-handler registration mechanism and code related to "shared" CPLs.
a) Combine t4_set_tcb_field and t4_set_tcb_field_rpl into a single function. Allow callers to direct the response to any iq. Tidy up set_ulp_mode_iscsi while there to use names from t4_tcb.h instead of magic constants.
b) Remove all CPL handler tables from struct adapter. This reduces its size by around 2KB. All handlers are now registered at MOD_LOAD instead of attach or some kind of initialization/activation. The registration functions do not need an adapter parameter any more.
c) Add per-iq handlers to deal with CPLs whose destination cannot be determined solely from the opcode. There are 2 such CPLs in use right now: SET_TCB_RPL and L2T_WRITE_RPL. The base driver continues to send filter and L2T_WRITEs over the mgmtq and solicits the reply on fwq. t4_tom (including the DDP code) now uses the port's ctrlq to send L2T_WRITEs and SET_TCB_FIELDs and solicits the reply on an ofld_rxq. fwq and ofld_rxq have different handlers that know what kind of tid to expect in the reply. Update t4_write_l2e and callers to to support any wrq/iq combination.

Note that this merge includes two different firmware updates, but the effective change is to update to the last version (1.15.37.0). As such, I've trimmed the log message of the first update (1.15.28.0).
In addition, the M_WAIT macro added in t4_regs.h had to be renamed to CXGBE_M_WAIT to avoid a collision on 10.x that is not present on 11.
295778: cxgbe: catch up with the latest hardware-related definitions.
296249: cxgbe(4): Update T5 and T4 firmwares to 1.15.28.0.
296333: cxgbe(4): First of many changes to reduce diffs with internal shared code:
- Rename some CamelCase variables. - s/t4_link_start/t4_link_l1cfg/g - Pull in t4_get_port_type_description. - Move t4_wait_op_done to t4_hw.c. - Flip the order of the RDMA stats. - Remove unsused function t4_iq_start_stop. - Move t4_wait_op_done and t4_wait_op_done_val to t4_hw.c
296383: cxgbe(4): Very basic T6 awareness. This is part of ongoing work to update to the latest internal shared code.
- Add a chip_params structure to keep track of hardware constants for all generations of Terminators handled by cxgbe. - Update t4_hw_pci_read_cfg4 to work with T6. - Update the hardware debug sysctls (hidden within dev.<tNnex>.<n>.misc.*) to work with T6. Most of the changes are in the decoders for the CIM logic analyzer and the MPS TCAM. - Acquire the regwin lock around indirect register accesses.
296471: cxgbe(4): Updated register dumps.
- Get the list of registers to read during a regdump from the shared code instead of the OS specific code. This follows a similar move internally. The shared code includes the list for T6.
- Update cxgbetool to be able to decode T5 VF, T6, and T6 VF register dumps (and catch up with some updates to T4 and T5 register decode).
296478: cxgbe(4): Add a struct sge_params to store per-adapter SGE parameters. Move the code that reads all the parameters to t4_init_sge_params in the shared code. Use these per-adapter values instead of globals.
296481: cxgbe(4): Overhaul the shared code that deals with the chip's TP block, which is responsible for filtering and RSS.
Add the ability to use filters that match on PF/VF (aka "VNIC id") while here. This is mutually exclusive with filtering on outer VLAN tag with Q-in-Q.
296485: cxgbe(4): Update the interrupt handlers for hardware errors.
296488: cxgbe(4): Updates to mailbox routines in the shared code.
296489: cxgbe(4): Updates to the shared routines that deal with the serial EEPROM, flash, and VPD.
296490: cxgbe(4): Remove __devinit and SPEED_<foo> as part of catch up with internal shared code.
296491: cxgbe(4): Updates to shared routines that get/set various parameters via the firmware.
296493: cxgbe(4): Use t4_link_down_rc_str in shared code to decode the reason the link is down, instead of doing it in OS specific code.
296494: cxgbe(4): Many new functions in the shared code, unused at this time.
296495: cxgbe(4): Fix t4_tp_get_rdma_stats.
296496: cxgbe(4): Minor updates to the shared routines that deal with firmware images.
296544: cxgbe(4): Reshuffle and rototill t4_hw.c, solely to reduce diffs with the internal shared code.
296710: cxgbe(4): Catch up with the latest list of card capabilities as reported by the firmware.
296711: cxgbe(4): Fix typo in previous commit.
297863: Rename the 'M_B' macro in t4_regs.h to 'CXGBE_M_B'.
This fixes a conflict with the M_B macro in powerpc's <machine/db_machdep.h> exposed by the recent addition of DDB commands to the cxgbe driver.
299685: cxgbe(4): Update T5 and T4 firmwares to 1.15.37.0.
These firmwares were obtained from the "Chelsio T5/T4 Unified Wire v2.12.0.3 for Linux" release. Changes since 1.14.4.0 (which is the firmware in -STABLE branches) are in the "Release Notes" accompanying the Unified Wire release and are copy-pasted here as well.

MFC 291665,291685,291856,297467,302110,302263: Add support for VIs.
291665: Add support for configuring additional virtual interfaces (VIs) on a port.
Each virtual interface has its own MAC address, queues, and statistics. The dedicated netmap interfaces (ncxgbeX / ncxlX) were already implemented as additional VIs on each port. This change allows additional non-netmap interfaces to be configured on each port. Additional virtual interfaces use the naming scheme vcxgbeX or vcxlX.
Additional VIs are enabled by setting the hw.cxgbe.num_vis tunable to a value greater than 1 before loading the cxgbe(4) or cxl(4) driver. NB: The first VI on each port is the "main" interface (cxgbeX or cxlX).
T4/T5 NICs provide a limited number of MAC addresses for each physical port. As a result, a maximum of six VIs can be configured on each port (including the "main" interface and the netmap interface when netmap is enabled).
One user-visible result is that when netmap is enabled, packets received or transmitted via the netmap interface are no longer counted in the stats for the "main" interface, but are not accounted to the netmap interface.
The netmap interfaces now also have a new-bus device and export various information sysctl nodes via dev.n(cxgbe|cxl).X.
The cxgbetool 'clearstats' command clears the stats for all VIs on the specified port along with the port's stats. There is currently no way to clear the stats of an individual VI.
291685: Fix build for !TCP_OFFLOAD case.
291856: Fix RSS build.
297467: Remove #ifdef's from various structures used in the cxgbe/cxl driver.
This provides a constant ABI and layout for these structures (especially struct adapter) avoiding some foot shooting.
302110: cxgbe(4): Merge netmap support from the ncxgbe/ncxl interfaces to the vcxgbe/vcxl interfaces and retire the 'n' interfaces. The main cxgbe/cxl interfaces and tunables related to them are not affected by any of this and will continue to operate as usual.
The driver used to create an additional 'n' interface for every cxgbe/cxl interface if "device netmap" was in the kernel. The 'n' interface shared the wire with the main interface but was otherwise autonomous (with its own MAC address, etc.). It did not have normal tx/rx but had a specialized netmap-only data path. r291665 added another set of virtual interfaces (the 'v' interfaces) to the driver. These had normal tx/rx but no netmap support.
This revision consolidates the features of both the interfaces into the 'v' interface which now has a normal data path, TOE support, and native netmap support. The 'v' interfaces need to be created explicitly with the hw.cxgbe.num_vis tunable. This means "device netmap" will not result in the automatic creation of any virtual interfaces.
The following tunables can be used to override the default number of queues allocated for each 'v' interface. nofld* = 0 will disable TOE on the virtual interface and nnm* = 0 to will disable native netmap support.
# number of normal NIC queues hw.cxgbe.ntxq_vi hw.cxgbe.nrxq_vi
# number of TOE queues hw.cxgbe.nofldtxq_vi hw.cxgbe.nofldrxq_vi
# number of netmap queues hw.cxgbe.nnmtxq_vi hw.cxgbe.nnmrxq_vi
hw.cxgbe.nnm{t,r}xq{10,1}g tunables have been removed.
--- tl;dr version --- The workflow for netmap on cxgbe starting with FreeBSD 11 is: 1) "device netmap" in the kernel config. 2) "hw.cxgbe.num_vis=2" in loader.conf. num_vis > 2 is ok too, you'll end up with multiple autonomous netmap-capable interfaces for every port. 3) "dmesg | grep vcxl | grep netmap" to verify that the interface has netmap queues. 4) Use any of the 'v' interfaces for netmap. pkt-gen -i vcxl<n>... . One major improvement is that the netmap interface has a normal data path as expected. 5) Just ignore the cxl interfaces if you want to use netmap only. No need to bring them up. The vcxl interfaces are completely independent and everything should just work. ---------------------
302263: cxgbe(4): Do not bring up an interface when IFCAP_TOE is enabled on it. The interface's queues are functional after VI_INIT_DONE (which is short of interface-up) and that's all that's needed for t4_tom to communicate with the chip.
