[PATCH] net: remove an assert call in eth_get_gso_type


From: P J P
Subject: [PATCH] net: remove an assert call in eth_get_gso_type
Date: Tue, 20 Oct 2020 13:41:19 +0530

From: Prasad J Pandit <pjp@fedoraproject.org>

eth_get_gso_type() routine returns segmentation offload type to use
based on L3 protocol type. It calls g_assert_not_reached if L3
protocol is unknown, making the following return statement unreachable.
Remove the g_assert call, as it maybe triggered by a guest user.
