From 197803ca31017f4fe52336a2a220796d0deb647a Mon Sep 17 00:00:00 2001 From: Manish Chopra Date: Mon, 4 Nov 2019 21:51:11 -0800 Subject: [PATCH] bnx2x: Fix PF-VF communication over multi-cos queues. [ Upstream commit dc5a3d79c345871439ffe72550b604fcde9770e1 ] PF driver doesn't enable tx-switching for all cos queues/clients, which causes packets drop from PF to VF. Fix this by enabling tx-switching on all cos queues/clients. Signed-off-by: Manish Chopra Signed-off-by: David S.
