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. Submitted by: Andrew Rybchenko Sponsored by: Solarflare Communications, Inc.

Mechanically substitute flags from historic mbuf allocator with

malloc(9) flags in sys/dev.

M_DONTWAIT is a flag from historical mbuf(9)

allocator, not malloc(9) or uma(9) flag.

Update recently added drivers to use the if_addr_rlock() wrapper

- There's no need to overwrite the default device method with the default

one. Interestingly, these are actually the default for quite some time (bus_generic_driver_added(9) since r52045 and bus_generic_print_child(9) since r52045) but even recently added device drivers do this unnecessarily. Discussed with: jhb, marcel - While at it, use DEVMETHOD_END. Discussed with: jhb - Also while at it, use __FBSDID.

sfxge: Remove interrupt self-test code

2011-11-19T09:16:52Z

It's not currently used; it didn't build on 32-bit and the previous build fix is incorrect. If we really implement self-tests we can do this again properly. Submitted by: Ben Hutchings MFC after: 3 weeks

sfxge: Fix if_baudrate reports

2011-11-19T09:13:58Z

This field is supposed to be set to the interface bit rate, but for some reason I thought it was denominated in kilobits. Multiply the values up accordingly, taking care to saturate rather than overflow on 32-bit architectures. Submitted by: Ben Hutchings MFC after: 3 weeks
