Subject: realtek: l3: add private structure
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=8c2ef13ec60979a8e15cf4016d4f9ace31cabdd7;p=thirdparty%2Fopenwrt.git

realtek: l3: add private structure

The DSA private structure provides an overwhelming mix of
information. L3 data is part of this. Provide a new separated
structure that is linked bidirectionally to the old data.
For the start it only contains a reference pointer and no L3
specific data.
