Michael Chan says:

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

Two main changes in this seris plus some miscellaneous changes.

1. Improvements and fixes for resource accounting which are required
for enabling SR-IOV and RDMA on the new 57500 chips.  Only SR-IOV
for 57500 chips is enabled in this series.

2. New statistics counters and improvements to keep the basic
counters and port counters during IFDOWN.

3. Msic. small changes for ETS, returning proper error codes
when flashing NVRAM, and a link speed related fix for ethtool
loopback selftest.
