[ Upstream commit 1a4a6a22552ca9d723f28a1fe35eab1b9b3d8b33 ]
Currently for MLO, sending out multicast frames on each link is handled by mac80211 only when IEEE80211_HW_MLO_MCAST_MULTI_LINK_TX flag is not set.
Dynamic VLAN multicast traffic utilizes software encryption. Due to this, mac80211 should handle transmitting multicast frames on all links for multicast VLAN traffic.
