mt7615E AP/VLAN

[regae]

this issue is only occur when using vlan_id in wpa_psk file or ppsk with freeradius (AP_VLAN),
no issue with standard AP

the only easy/simple way i can reproduce this is by viewing remote vnc (same local network)
so i think its UDP related, here's what i'm experiencing

• connection got dropped, wifi still connected
• no communication to/from after it got dropped

tested with snapshot - 21.02 branch
tested devices: ea7500 v2, ea8100 v1, re650 v1

after a week of fiddling around,
reverting this commit fix the issue i have, 0ed6a33
or just remove ieee80211_send_bar() inside case IEEE80211_AMPDU_TX_OPERATIONAL

i understand mt7615 is an old device so it may not be the focus anymore,
but please could you take a look at this particular commit @nbd168

thank you

Please test latest snapshot or 23.05.4

already tried with snapshot, 23.05, 22.03, 21.02
every new version of kernel or mac80211 or mt76 already tested.

the only way so far is to remove ieee80211_send_bar()
