MFC r266571, r266757, r268536, r269076, r269364, r269366, r269411, r269413, r269428, r269440, r269537, r269644, r269731, and the cxgbe portion of r270063.
r266571: cxgbe(4): Remove stray if_up from the code that creates the tracing ifnet.
r266757: cxgbe(4): netmap support for Terminator 5 (T5) based 10G/40G cards. Netmap gets its own hardware-assisted virtual interface and won't take over or disrupt the "normal" interface in any way. You can use both simultaneously.
For kernels with DEV_NETMAP, cxgbe(4) carves out an ncxl<N> interface (note the 'n' prefix) in the hardware to accompany each cxl<N> interface. These two ifnet's per port share the same wire but really are separate interfaces in the hardware and software. Each gets its own L2 MAC addresses (unicast and multicast), MTU, checksum caps, etc. You should run netmap on the 'n' interfaces only, that's what they are for.
With this, pkt-gen is able to transmit > 45Mpps out of a single 40G port of a T580 card. 2 port tx is at ~56Mpps total (28M + 28M) as of now. Single port receive is at 33Mpps but this is very much a work in progress. I expect it to be closer to 40Mpps once done. In any case the current effort can already saturate multiple 10G ports of a T5 card at the smallest legal packet size. T4 gear is totally untested.

Reorganize struct sge_iq. Make the iq entry size a compile time constant. While here, eliminate RX_FL_ESIZE and use EQ_ESIZE directly.

MFC r268640 and r268989.
r268640: Allow multi-byte reads in the private CHELSIO_T4_GET_I2C ioctl. The firmware allows up to 48B to be read this way but the driver limits itself to 8B at a time to remain compatible with old cxgbetool binaries.

These can be used for various kinds of tx traffic throttling (to force selected tx queues to drain at a fixed Kbps rate, or a % of the port's total bandwidth, or at a fixed pps rate, etc.).
r259048: Two new cxgbetool subcommands to set up scheduler classes and to bind them to NIC queues.

cxgbe(4): Add support for Chelsio's Terminator 5 (aka T5) ASIC. This includes support for the NIC and TOE features of the 40G, 10G, and 1G/100M cards based on the T5.
The ASIC is mostly backward compatible with the Terminator 4 so cxgbe(4) has been updated instead of writing a brand new driver. T5 cards will show up as cxl (short for cxlgb) ports attached to the t5nex bus driver.

cxgbe(4): Consider all the API versions of the interfaces exported by the firmware (instead of just the main firmware version) when evaluating firmware compatibility. Document the new "hw.cxgbe.fw_install" knob being introduced here.
This should fix kern/173584 too. Setting hw.cxgbe.fw_install=2 will mostly do what was requested in the PR but it's a bit more intelligent in that it won't reinstall the same firmware repeatedly if the knob is left set.

Add a driver ioctl to read a byte from any device on a port's i2c bus. This lets userspace read arbitrary information from the SFP+ modules etc. on this bus.
Reading multiple bytes in the same transaction isn't possible right now. I'll update the driver once the chip's firmware supports this.

Many updates to cxgbe(4)
- Device configuration via plain text config file. Also able to operate when not attached to the chip as the master driver.
- Generic "work request" queue that serves as the base for both ctrl and ofld tx queues.
- Generic interrupt handler routine that can process any event on any kind of ingress queue (via a dispatch table).
- A couple of new driver ioctls. cxgbetool can now install a firmware to the card ("loadfw" command) and can read the card's memory ("memdump" and "tcb" commands).
- Lots of assorted information within dev.t4nex.X.misc.* This is primarily for debugging and won't show up in sysctl -a.
- Code to manage the L2 tables on the chip.
- Updates to cxgbe(4) man page to go with the tunables that have changed.
- Updates to the shared code in common/
- Updates to the driver-firmware interface (now at fw 1.4.16.0)
