Subject: [PATCH net 1/1] qede: Disable hardware gro when xdp prog is installed
Date: Thu, 19 Dec 2019 10:35:16 -0800 [thread overview]
Message-ID: <20191219183516.7017-1-manishc@marvell.com> (raw)
commit 18c602dee472 ("qede: Use NETIF_F_GRO_HW.") introduced
a regression in driver that when xdp program is installed on
qede device, device's aggregation feature (hardware GRO) is not
getting disabled, which is unexpected with xdp.
Fixes: 18c602dee472 ("qede: Use NETIF_F_GRO_HW.")
