[PATCH 5.19 050/207] wifi: mt76: fix reading current per-tid starting sequence number for aggregation

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Felix Fietkau <nbd@xxxxxxxx>

commit c3a510e2b53785df31d882a773c4c0780b4c825f upstream.

The code was accidentally shifting register values down by tid % 32 instead of
(tid * field_size) % 32.
