X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=a549e4fa5e5d624e07081c7c27a52f8932f228bd;p=karo-tx-linux.git net: fec: Fix multicast list setup in fec_restart(). Setup the multicast list of the net_device instead of clearing it blindly. This restores the multicast groups in case of a link down/up event or when resuming from suspend.
