Merge branch 'bnxt_en-next' 

Michael Chan says:

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

First, we upgrade the firmware interface spec.  Due to a change in
the toolchains, the auto-generated bnxt_hsi.h does not match the
old bnxt_hsi.h and the patch is really big.  This should be just
one-time.  Going forward, changes should be incremental.

The next 10 patches implement a new scheme for the PF and VF drivers
to allocate and reserve resources.  The new scheme is more flexible
and allows dynamic and asymmetric distribution of resources, whereas
the old scheme is static and even distribution.

The last few patches add cacheline size setting, a couple of PCI IDs,
better management of VF MAC address, and a better parent switchdev ID
for dual-port devices.
====================
