[dpdk-dev] [INTERNAL REVIEW 2/7] net/qede: fix incorrect queue id for 100G

[Rasesh Mody]

From: Harish Patil <harish.pa...@cavium.com>

'commit 4c4bdadfa9e7 ("net/qede: refactoring multi-queue implementation")'
introduced a regression where default RSS configuration is incorrect in
the case of 100G mode. Currently we are passing absolute queue ids while
creating RX/TX queues. But in CMT mode we need to provide queue id
relative to the engine id. So this fix takes into account num_hwfns
while creating queues.

Fixes: 4c4bdadfa9e7 ("net/qede: refactoring multi-queue implementation")
