sfxge(4): use n Tx queues instead of n + 2 on EF10 HW
On EF10 HW we can avoid sending packets without checksum offload or with IP-only checksum offload to dedicated queues. Instead, we can use option descriptors to change offload policy on any queue during runtime. Thus, we don't need to create two dedicated queues.

Revert r330897:
This was intended to be a non-functional change. It wasn't. The commit message was thus wrong. In addition it broke arm, and merged crypto related code.
Revert with prejudice.
This revert skips files touched in r316370 since that commit was since MFCed. This revert also skips files that require $FreeBSD$ property changes.
Thank you to those who helped me get out of this mess including but not limited to gonzo, kevans, rgrimes.

MFC r311877
sfxge(4): avoid unnecessary mbuf data prefetch
Unnecessary prefetch just loads HW prefetcher and displaces other cache entries (which could be really useful).
If we parse mbuf for TSO early and use firmware-assisted TSO, we do not expect mbuf data access when we compose firmware-assisted TSO (v1 or v2) option descriptors. If packet header needs to be linearized or finally FATSO cannot be used because of, for example, too big header, we do not care about a bit more performance degradation because of prefetch absence (it is better to optimize more common case).

sfxge: relax assertion to allow RST flag in TSO packets
Kernel under stress load, mixed MC reboot and sfupdate really generates TSO packet with RST flag. It will generate many TCP packets with RST flag set. May be RST flag should be set in the last segment only, but it could be dropped. So, it is safer to keep the flag in all packets to be sure that connection is reset.

sfxge: fix overflow queue freeze
If TxQ lock is obtained, deferred packet list shold be serviced even if the packet addition fails because of overflow.
Without the patch freeze happens if: - queue is not blocked (i.e. completion does not trigger unblock and service) - put-list overflow (1024 entries) - sfxge_tx_packet_add() acquires TxQ lock just as it is released it in sfxge_tx_qdpl_service() on the second CPU but before pending check - sfxge_tx_packet_add() swizzles put-list to get-list, fails because of non-tcp get-list overflow and returns without packet list service - sfxge_tx_qdpl_service() on the second CPU checks that there are no pending packets in the put-list and returns
Other possible solution is to guaranee that maximum length of the put-list is less than maximum length of any get-list.

sfxge: assert either kernel or internal copy of interface flags
ioctl to put interface down sets ifp->if_flags which holds the intended administratively defined state and calls driver callback to apply it. When everything is done, driver updates internal copy of interface flags sc->if_flags which holds the operational state. So, transmit from Rx path is possible when interface is intended to be administratively down in accordance with ifp->if_flags, but not applied yet and the operational state is up in accordance with sc->if_flags.

Start process of removing the use of the deprecated "M_FLOWID" flag from the FreeBSD network code. The flag is still kept around in the "sys/mbuf.h" header file, but does no longer have any users. Instead the "m_pkthdr.rsstype" field in the mbuf structure is now used to decide the meaning of the "m_pkthdr.flowid" field. To modify the "m_pkthdr.rsstype" field please use the existing "M_HASHTYPE_XXX" macros as defined in the "sys/mbuf.h" header file.
This patch introduces new behaviour in the transmit direction. Previously network drivers checked if "M_FLOWID" was set in "m_flags" before using the "m_pkthdr.flowid" field. This check has now now been replaced by checking if "M_HASHTYPE_GET(m)" is different from "M_HASHTYPE_NONE". In the future more hashtypes will be added, for example hashtypes for hardware dedicated flows.
"M_HASHTYPE_OPAQUE" indicates that the "m_pkthdr.flowid" value is valid and has no particular type. This change removes the need for an "if" statement in TCP transmit code checking for the presence of a valid flowid value. The "if" statement mentioned above is now a direct variable assignment which is then later checked by the respective network drivers like before.
Additional notes: - The SCTP code changes will be committed as a separate patch. - Removal of the "M_FLOWID" flag will also be done separately. - The FreeBSD version has been bumped.

The driver supports jumbo frames, transmit/receive checksum offload, TCP Segmentation Offload (TSO), Large Receive Offload (LRO), VLAN checksum offload, VLAN TSO, and Receive Side Scaling (RSS) using MSI-X interrupts.
