Subject: [PATCH 5.1 92/98] mlxsw: spectrum: Prevent force of 56G
Date: Thu, 20 Jun 2019 19:57:59 +0200 [thread overview]
Message-ID: <20190620174354.016514010@linuxfoundation.org> (raw)
In-Reply-To: <20190620174349.443386789@linuxfoundation.org>
[ Upstream commit 275e928f19117d22f6d26dee94548baf4041b773 ]
Force of 56G is not supported by hardware in Ethernet devices. This
configuration fails with a bad parameter error from firmware.
Add check of this case. Instead of trying to set 56G with autoneg off,
return a meaningful error.
Fixes: 56ade8fe3fe1 ("mlxsw: spectrum: Add initial support for Spectrum ASIC")
