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

Michael Chan says:

====================
bnxt_en: Update for net-next

The first 4 patches in the series fix issues in the net-next tree
introduced in the last 4 weeks.  The first 3 patches fix ring accounting
and indexing logic.  The 4th patch fix TX timeout when the TX ring is
very small.

The next 7 patches add new features on the P7 chips, including TX
coalesced completions, VXLAN GPE and UDP GSO stateless offload, a
new rx_filter_miss counters, and more QP backing store memory for
RoCE.

The last 2 patches are PTP improvements.
