Merge branch 'bnxt_en-Updates-for-net-next'

Michael Chan says:

====================
bnxt_en: Updates for net-next.

This patch series adds TC Flower tunnel decap and rewrite actions in
the first 4 patches.  The next 3 patches integrates the recently
added error recovery with the RDMA driver by calling the proper
hooks to stop and start.

v2: Fix pointer alignment issue in patch #1.
====================
