Hi Johannes, Let me also replace SAP with SoftAP. So now commit text would be: cfg80211/nl80211: Add API to report frequency range(s) to be avoided Add support for WLAN driver to report frequency range(s) to be avoided because of interference. If SoftAP/P2P-GO is operating on interfering frequency then user space should stop and restart them avoiding interfering frequency range(s). User space may decide to continue operation on interfering frequency, but in such case, there might be impact on performance.

Purpose of this patch is to add an API for WLAN driver to report frequency ranges which should be avoided for SAP/P2P-GO because of interference. How about if I reword commit test as below? cfg80211/nl80211: Add API to report frequency range(s) to be avoided Add support for WLAN driver to report frequency range(s) to be avoided because of interference.

SAP? I don't think SAP will move - they're pretty stuck in Walldorf :P This is pretty strange patch, and very little justification. "Unsafe" is also a really bad word. johannes ��.n��������+%������w��{.n�����{���zW����ܨ}���Ơz�j:+v�����w����ޙ��&�)ߡ�a����z�ޗ���ݢj��w�f
