[dpdk-dev] [PATCH v4 26/32] net/qede: skip slowpath polling for 100G VF device

From: Harish Patil <harish.patil at 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: 2af14ca79c0a ("net/qede: support 100G")
