Subject: [PATCH AUTOSEL 4.19 48/73] net/mlx4_en: Change min MTU size to ETH_MIN_MTU
Date: Wed, 12 Dec 2018 23:28:13 -0500 [thread overview]
Message-ID: <20181213042838.75160-48-sashal@kernel.org> (raw)
In-Reply-To: <20181213042838.75160-1-sashal@kernel.org>
From: Eran Ben Elisha <eranbe@mellanox.com>
[ Upstream commit 24be19e47779d604d1492c114459dca9a92acf78 ]
NIC driver minimal MTU size shall be set to ETH_MIN_MTU, as defined in
the RFC791 and in the network stack. Remove old mlx4_en only define for
it, which was set to wrong value.
Fixes: b80f71f5816f ("ethernet/mellanox: use core min/max MTU checking")
