[dpdk-dev] [PATCH 48/50] net/bnxt: fill cfa_action in the tx buffer descriptor properly

From: Venkat Duvvuru <venkatkumar.duvvuru at broadcom.com>

Currently, only vfrep transmit requires cfa_action to be filled
in the tx buffer descriptor. However with truflow, dpdk(non vfrep)
to port also requires cfa_action to be filled in the tx buffer
descriptor.

This patch uses the correct cfa_action pointer while transmitting
the packet. Based on whether the packet is transmitted on non-vfrep
or vfrep, tx_cfa_action or vfr_tx_cfa_action inside txq will be
filled in the tx buffer descriptor.
