ixl(4): Add FW recovery mode support and other things
Update the iflib version of ixl driver based on the OOT version ixl-1.11.29. Major changes: - Extract iflib specific functions from ixl_pf_main.c to ixl_pf_iflib.c to simplify code sharing between legacy and iflib version of driver - Add support for most recent FW API version (1.10), which extends FW LLDP Agent control by user to X722 devices - Improve handling of device global reset - Add support for the FW recovery mode - Use virtchnl function to validate virtual channel messages instead of using separate checks - Fix MAC/VLAN filters accounting Submitted by: Krzysztof Galazka <krzysztof.galazka@intel.com> Reviewed by: erj@ Tested by: Jeffrey Pieper <jeffrey.e.pieper@intel.com> MFC after: 1 week Relnotes: yes Sponsored by: Intel Corporation Differential Revision: https://reviews.freebsd.org/D24564
