Subject[PATCH net-next 05/13] net: mvpp2: do not force the link mode
Date
The link mode (speed, duplex) was forced based on what the phylib
returns. This should not be the case, and only forced by ethtool
functions manually. This patch removes the link mode enforcement from
the phylib link_event callback.
