Merge branch 'bnxt_en-updates' 

Michael Chan says:

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

-Add default VLAN support for VFs.
-Add NPAR (NIC partioning) support.
-Add support for new device 5731x and 5741x. GRO logic is different.
-Support new ETHTOOL_{G|S}LINKSETTINGS.
====================
