Re: [PATCH net v5 0/4] net: enable inband link state negotiation only when explicitly requested

Hi guys,

Changes in v5:

  why this is required

Initial cover letter from Stas:

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.
More details here:
https://lkml.org/lkml/2015/7/10/206

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.

FWIW, I tested this v5 series on mirabox (2 mvneta interfaces using
RGMII); both interfaces still work as expected, i.e. no regression
on my side.
