Hi Jie Feng,
Thanks for the v2. The fix looks right to me, just one small comment
below.

As far as I can see this is the normal TX completion of the aggregate
buffer, so I think dev_consume_skb_any() fits better here.
dev_kfree_skb_any() frees it with SKB_DROP_REASON_NOT_SPECIFIED, so each
aggregated transfer would now show up as a drop in the skb:kfree_skb
tracepoint and in drop monitor.
Before this patch the buffer went through mac80211, which in the usual
case freed it with dev_kfree_skb(), and that is consume_skb().
Best regards,
Luka Gejak
