Subject: Add vendor attribute to enable DFS No Wait support
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b5e326d24298ac52fba3c4e5ba5ae79780c78dc9;p=thirdparty%2Fhostap.git

Add vendor attribute to enable DFS No Wait support

This change adds QCA_WLAN_VENDOR_ATTR_CONFIG_DFS_NO_WAIT_SUPPORT to
enable DFS No Wait support.

If an AP starts on a channel with a bandwidth larger than 20 MHz,
which includes both DFS required and non DFS required subsets, it
should begin beaconing immediately on the non DFS required subset
while simultaneously monitoring for radar events once the DFS No Wait
feature is enabled.
