bgmac: add ndo_set_rx_mode netdev ops
When changing the device from or to promisc mode this only affects the device after the device is bought up the next time. For bridging it is needed to change the device to promisc mode while it is up, which is possible with this patch. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> Signed-off-by: David S.
