[RFC 21/21] cfg80211: remove channel_switch combination check

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Make the driver responsible for making sure it is
capable of performing the switch. It might as well
accept a request but then disconnect an interface
if some requirements are not met.

In that case userspace should be prepared for an
appropriate event (AP/IBSS/mesh being stopped/left).
