Currently, base and nb_queue in the tc_rxq and tc_txq information
of queue and TC mapping on both TX and RX paths are uint8_t.
However, these data will be truncated when queue number under a TC
is greater than 256. So it is necessary for base and nb_queue to
change from uint8_t to uint16_t.

cc'ed tech-board,
The patch breaks the ethdev ABI without a deprecation notice from previous
release(s).
It is increasing the storage size of the fields to support more than 255 queues.
Yes queues are in 16-bit range.
Since the ethdev library already heavily breaks the ABI this release, I am for
getting this patch, instead of waiting for one more year for the update.
Can you please review the patch, is there any objection to proceed with it?

I will continue with this patch (not patchset) if there is no objection.
