Setting IBSS mode when stopping AP may affect functionality of INFRA
mode on another interface. For instance, if user creates and stops
hostap daemon on virtual interface, then association cannot work on
primary interface because default BSS has been set to IBSS mode in
firmware side. The IBSS mode should be set when cfg80211 changes the

The title talks about setting IBSS mode but the code looks to be about
setting INFRA mode. Is this correct?

Both are correct :-p Have to admit this is confusing. The command SET_INFRA with zero value means "disable INFRA; thus enable IBSS".

I would rephrase the commit message indeed explaining what the code currently does, ie.:

Upon stopping an AP interface the driver disable INFRA mode effectively setting the interface in IBSS mode. However, this may affect other interfaces running in INFRA mode. For instance, ....
