Merge branch 'bnxt_en-misc-small-fixes'

Michael Chan says:

====================
bnxt_en: Misc. small fixes.

Fixes include moving the initial function reset, notifying the RDMA driver
during tx timeout, setting dcbx_cap properly depending on whether the
firmware agent is running or not, and an autoneg related improvement.
