Subject: net: mtk_eth_soc: use resolved link config in mac_link_up()
X-Git-Tag: microblaze-v5.10~134^2~453
X-Git-Url: http://git.monstr.eu/?a=commitdiff_plain;h=75674e31593ba3b18459816d9b52b3d87dbfadc0;p=linux-2.6-microblaze.git

net: mtk_eth_soc: use resolved link config in mac_link_up()

Convert the mtk_eth_soc driver to use the finalised link parameters in
mac_link_up() rather than the parameters in mac_config().
