Something that might be worthwhile for upstream? I have seen lots of out-of-tree drivers having something like this but I doubt that something like this would be acceptable in upstream. Anyway this is something which should be discussed in linux-wireless with a wider audience, maybe even in lkml. -- Kalle Valo _______________________________________________ ath10k mailing list [email protected] http://lists.infradead.org/mailman/listinfo/ath10k
