Series [1/3] batman-adv: Drop deprecated sysfs support | expand

Commit Message

Sven Eckelmann Oct. 31, 2020, 5:38 p.m. UTC
The only way to automatically drop batadv mesh interfaces when all soft
interfaces were removed was dropped with the sysfs support. It is no longer
needed to have them handled by kernel anymore.
