[dpdk-dev] [PATCH v2 06/20] net/sfc: introduce ethdev Tx queue ID

[Andrew Rybchenko <andrew.rybchenko@oktetlabs.ru>]

From: Igor Romanov <igor.romanov@oktetlabs.ru>

Make software index of a Tx queue and ethdev index separate.
When an ethdev TxQ is accessed in ethdev callbacks, an explicit ethdev
queue index is used.

This is a preparation to introducing non-ethdev Tx queues.
