From: Andrei Otcheretianski Date: Wed, 9 Jul 2014 15:59:14 +0000 (+0300) Subject: iwlwifi: mvm: Set RRM_ENABLED bit in scan commands X-Git-Tag: v3.18-rc1~10^2~75^2~82^2~13 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=73897bd1d949d34b7a38a2cd14302d91f68ef12d;p=platform%2Fkernel%2Flinux-exynos.git iwlwifi: mvm: Set RRM_ENABLED bit in scan commands Set RRM_ENABLED (bit 6) flag in scan commands. When this flag is set the fw will add WFA vendor-specific TPC report and DS parameter set IEs into probe requests. This bit is set for SCAN_OFFLOAD_REQUEST_CMD(0x51).
