wifi: iwlwifi: mvm: include link ID when releasing frames
Browse files Browse the repository at this point in the history
When releasing frames from the reorder buffer, the link ID was not
included in the RX status information. This subsequently led mac80211 to
drop the frame. Change it so that the link information is set
immediately when possible so that it doesn't not need to be filled in
anymore when submitting the frame to mac80211.
