From 093324816b91c9f4a3dd8c78930e43d0a2ef2508 Mon Sep 17 00:00:00 2001 From: Michal Kazior Date: Wed, 9 Apr 2014 15:29:25 +0200 Subject: [PATCH] mac80211: add support for radar detection for reservations Initial chanctx reservation code wasn't aware of radar detection requirements. This is necessary for chanctx reservations to be used for channel switching in the future.
