Subject: net: stmmac: move default_an_inband to plat_stmmacenet_data
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=9a475dc71c38d6abc42ba722ace4a72372876d91;p=thirdparty%2Flinux.git

net: stmmac: move default_an_inband to plat_stmmacenet_data

Move the default_an_inband flag from struct mdio_bus_data to struct
plat_stmmacenet_data. This is to allow platforms that do not use the
integrated MDIO bus to enable inband mode.
