Subject: [PATCH 077/179] brcmfmac: Fix authentication latency caused by OBSS
|
|
stats survey
|
|
|
|
Auto Channel Select feature of HostAP uses dump_survey to fetch
|
|
OBSS statistics. When the device is in the middle of an authentication
|
|
sequence or just at the end of authentication completion, running
|
|
dump_survey would trigger a channel change. The channel change in-turn
|
|
can cause packet loss, resulting in authentication delay. With this change,
|
|
dump_survey wont be run when authentication or association is in progress &
|
|
hence resolving the issue.
