263302: fix mbuf leak if it does not fit in software queue
264461: Commit various fixes for the SolarFlare drivers, in particular this set of patches fixes support for systems with > 32 cores.
Details include
sfxge: RXQ index (not label) comes from FW in flush done/failed events
Change the second argument name of the efx_rxq_flush_done_ev_t and efx_rxq_flush_failed_ev_t prototypes to highlight that RXQ index (not label) comes from FW in flush done and failed events.
sfxge: TXQ index (not label) comes from FW in flush done event
Change the second argument name of the efx_txq_flush_done_ev_t prototype to highlight that TXQ index (not label) comes from FW in flush done event.
sfxge: use TXQ type as label to support more than 32 TXQs
There are 3 TXQs in event queue 0 and 1 TXQ (with TCP/UDP checksum offload) in all other event queues.
264772: Check that port is started when MAC filter is set
The MAC filter set may be called without softc_lock held in the case of SIOCADDMULTI and SIOCDELMULTI ioctls. The ioctl handler checks IFF_DRV_RUNNING flag which implies port started, but it is not guaranteed to remain. softc_lock shared lock can't be held in the case of these ioctls processing, since it results in failure where kernel complains that non-sleepable lock is held in sleeping thread.
Both problems are repeatable on LAG with LACP proto bring up.

Add the sfxge(4) device driver, providing support for 10Gb Ethernet adapters based on Solarflare SFC9000 family controllers. 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.
