[dpdk-dev] [PATCH 14/17] qede: skip slowpath polling for 100G VF device

[Rasesh Mody <rasesh.mody@qlogic.com>]

From: Harish Patil <harish.patil@qlogic.com>

There is no need to poll for slowpath events for VF
device since the ramrod responses are received over
PF-VF backchannel synchronously. So the fix is to
restrict the slowpath polling for PF device only.

Fixes 2af14ca ("net/qede: support 100G")
