mac80211: implement set_mcast_rate() callback (391e53e3) · Commits · 戴 / test

This new callback can be used to tune the rate to be used to send multicast frames. In the current state the multicast rate can be specified on IBSS/MESH joining only. This makes it impossible to select a custom multicast rate when then join command is sent by an external program (e.g. wpa_supplicant) Signed-off-by:
