Subject: QCA vendor attribute to allow P2P SCC with STA connected DFS channel
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=c513a40770e8ef64be3c5707c852c97768110211;p=thirdparty%2Fhostap.git

QCA vendor attribute to allow P2P SCC with STA connected DFS channel

Define config attributes to support STA connected DFS channel for P2P.
Add a new feature flag
@QCA_WLAN_VENDOR_FEATURE_SUPPORT_STA_DFS_CH_SCC_P2P for the driver to
indicate STA connected DFS channel SCC support.
