Subject: [PATCH] iwlwifi: sta: defer ADDBA transmit in case reclaimed SN != next SN
Git-commit: 7e0ca7230b980b451c8265fbe75e5bd47fd832a9
Patch-mainline: v5.10-rc1
References: bsc#1187495
This avoids cases that we have a lot of packets in the queue and until we
are able to transmit SSN packet the other side sends DELBA due to timeout.
