X-Git-Tag: hostap_2_2~483
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=70634eec0cb0003d83a8f25419eabf2d928dfc83;p=thirdparty%2Fhostap.git

hostapd: Check driver DFS offload capability for channel disablement

If the driver supports full offloading of DFS operations, do not disable
a channel marked for radar detection. The driver will handle the needed
operations for such channels.
