From de027ce7cea8cbd1ef4b8b6ec536a139d6bdc3c4 Mon Sep 17 00:00:00 2001 From: Harish Patil Date: Tue, 18 Oct 2016 21:11:40 -0700 Subject: [PATCH] net/qede: skip slow path polling for 100G VF device 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.
