This causes a crash in places which assume that rx->link\_sta is valid if rx->sta is valid. One known instance is triggered by \_\_ieee80211\_rx\_h\_amsdu being called from fast-rx. It results in a crash like this one: BUG: kernel NULL pointer dereference, address: 00000000000000a8 #PF: supervisor write access in kernel mode #PF: error\_code(0x0002) - not-present page PGD 0 P4D 0 Oops: 0002 [#1] PREEMPT SMP PTI CPU: 1 PID: 506 Comm: mt76-usb-rx phy Tainted: G E 6.1.0-debian64x+1.7 #3 Hardware name: ZOTAC ZBOX-ID92/ZBOX-IQ01/ZBOX-ID92/ZBOX-IQ01, BIOS B220P007 05/21/2014 RIP: 0010:ieee80211\_deliver\_skb+0x62/0x1f0 [mac80211] Code: 00 48 89 04 24 e8 9e a7 c3 df 89 c0 48 03 1c c5 a0 ea 39 a1 4c 01 6b 08 48 ff 03 48 83 7d 28 00 74 11 48 8b 45 30 48 63 55 44 <48> 83 84 d0 a8 00 00 00 01 41 8b 86 c0 11 00 00 8d 50 fd 83 fa 01 RSP: 0018:ffff999040803b10 EFLAGS: 00010286 RAX: 0000000000000000 RBX: ffffb9903f496480 RCX: 0000000000000000 RDX: 0000000000000000 RSI: 0000000000000000 RDI: 0000000000000000 RBP: ffff999040803ce0 R08: 0000000000000000 R09: 0000000000000000 R10: 0000000000000000 R11: 0000000000000000 R12: ffff8d21828ac900 R13: 000000000000004a R14: ffff8d2198ed89c0 R15: ffff8d2198ed8000 FS: 0000000000000000(0000) GS:ffff8d24afe80000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 00000000000000a8 CR3: 0000000429810002 CR4: 00000000001706e0 Call Trace: \_\_ieee80211\_rx\_h\_amsdu+0x1b5/0x240 [mac80211] ? ieee80211\_prepare\_and\_rx\_handle+0xcdd/0x1320 [mac80211] ? \_\_local\_bh\_enable\_ip+0x3b/0xa0 ieee80211\_prepare\_and\_rx\_handle+0xcdd/0x1320 [mac80211] ? prepare\_transfer+0x109/0x1a0 [xhci\_hcd] ieee80211\_rx\_list+0xa80/0xda0 [mac80211] mt76\_rx\_complete+0x207/0x2e0 [mt76] mt76\_rx\_poll\_complete+0x357/0x5a0 [mt76] mt76u\_rx\_worker+0x4f5/0x600 [mt76\_usb] ? mt76\_get\_min\_avg\_rssi+0x140/0x140 [mt76] \_\_mt76\_worker\_fn+0x50/0x80 [mt76] kthread+0xed/0x120 ? kthread\_complete\_and\_exit+0x20/0x20 ret\_from\_fork+0x22/0x30 Since the initialization of rx->link and rx->link\_sta is rather convoluted and duplicated in many places, clean it up by using a helper function to set it.
