Series wifi: mac80211: MLO handling for Dynamic VLAN | expand

Commit Message

Muna Sinada March 7, 2025, 12:37 a.m. UTC 
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.
