[PATCH v4 51/57] net/bnxt/tf_ulp: add support for unicast only feature

[Manish Kurup]

From: Kishore Padmanabha <kishore.padmanabha at broadcom.com>

Added support for unicast only feature bit in the truflow application.
This enables the application to not receive broadcast, multicast or
unknown mac addresses to the ports that are participating in the
application.
