This patch series addresses issues related to the handling of Rx group
addressed data and management frames in multi-radio devices with ath12k
driver. These frames don't have the destination station information, unlike
unicast Rx frames, and are forwarded to all the active sdata of the device.
This happens because currently there is no check to ensure if the sdata is
running on the same band as the frames are received on before start
processing those frames.
The patches ensure that packets are correctly processed and forwarded only
to the appropriate interfaces by mandating the ieee80211_rx_status::freq
for group addressed data frames and check the operating frequency against
the rx_status->freq and forward to the appropriate interface when the
frequency matches.
This series fails hwsim tests due to lockdep complaints.
This is because of this macro for_each_link_data() using
sdata_dereference instead of rcu_dereference.
Will fix this in the next version.
