Sumit Saxena 58d84ef870 if_bnxt: Added support for mgmt interface for passthrough hwrms 
Added support for application management interface. There are two types of commands supported:

1. Firmware IOCTLs: These ioctls are meant for firmware
   consumption. Driver acts as a transport for these.
2. Driver only IOCTLs: These ioctls are meant for driver
   consumption. Driver will serve these ioctls without sending them down
   to firmware.
