Subject: realtek: mdio: create new bus structure
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=c6ccca619c87f610d40e93b70fcd259eb3744618;p=thirdparty%2Fopenwrt.git

realtek: mdio: create new bus structure

The port specific attributes of the central control structure
have been moved over to a separate port structure. Do the same
for the (up to 4) busses. Establish a separate bus structure
that will hold data about each bus and use it in the control
structure. As a first usage type move the is_c45 attribute over.
