[B.A.T.M.A.N.] [PATCH 4/4] batman-adv: Group ethtool related code together

Sven Eckelmann
2017-04-01T12:47:06Z

The ethtool code was spread in soft-interface.c. This makes reading the
code and working on it unnecessary complicated. Having everything in a
common place next to the other code which references it, makes it slightly
easier.
