cdc-ether: handle promiscuous mode with a set_rx_mode callback
Promiscuous mode was not supported anymore with my Lenovo adapters (RTL8153) since commit c472ab68ad67db23c9907a27649b7dc0899b61f9 (cdc-ether: clean packet filter upon probe). It was not possible to use them in a bridge anymore. Signed-off-by: Olivier Blin <olivier.blin@softathome.com> Also-analyzed-by: Loïc Yhuel <loic.yhuel@softathome.com> Signed-off-by: David S.
