From 70634eec0cb0003d83a8f25419eabf2d928dfc83 Mon Sep 17 00:00:00 2001 From: Amar Singhal Date: Sat, 22 Mar 2014 21:31:15 +0200 Subject: [PATCH] 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.
