Merge branch 'be2net-error-recovery-and-bug-fixes'
Sriharsha Basavapatna says: ==================== be2net: patch-set The following patch set contains an error recovery feature and a few bug fixes. Please consider applying this to the net-next tree. Thanks. Patch-1 Supports HW error recovery in Skyhawk/BEx adapters Patch-2 Fixes driver unload to issue function reset FW command Patch-3 Avoids issuing GET_EXT_FAT_CAPABILITIES command for VFs Patch-4 Avoids redundant addition of mac address in HW Patch-5 Fixes mac address collision in some configurations Patch-6 Updates driver version ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
