Subject: batman-adv: Move deinitialization of soft-interface to destructor
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=b3246020e27ecc7c50cc77535936987d6eb6c869;p=openwrt%2Fstaging%2Fblogic.git

batman-adv: Move deinitialization of soft-interface to destructor

The deinitialization of the soft-interface created in ndo_init/constructor
should be done in the destructor and not directly before calling
unregister_netdevice
