Subject: [PATCH 0/2] enable inband link state negotiation only when explicitly requested
Date: Thu, 09 Jul 2015 20:34:28 +0300 [thread overview]
Message-ID: <559EB0A4.5080101@list.ru> (raw)
Hello.
Currently the link status auto-negotiation is enabled
for any SGMII link with fixed-link DT binding.
The regression was reported:
https://lkml.org/lkml/2015/7/8/865
Apparently not all HW that implements SGMII protocol, generates the
inband status for the auto-negotiation to work.
The following patches reverts to the old behavior by default,
which is to not enable the auto-negotiation for fixed-link.
The new DT property is added that allows to explicitly request
the auto-negotiation.
Those who were affected by the change, please send your Tested-by,
Thanks!
