From: Kiran Kumar K <kirankumark@marvell.com>
Adding support for send queue flow matching item.
This item is valid only for egress rules.
An example use case would be that application can
set different vlan insert rules with different PCP values
based on tx queue number.

Hi all,
I'd like to test this feature somehow but this patch just implements the API... Will there
be some PMD support soon? I could see that mlx5 implements some internal hidden RTE Flow
item SC already that matches this behaviour... It would be great to make it available
via this TX_QUEUE feature. Any plans for this (Ori)?
