From 97bd8c79dae272829f5363e994639bca5ffd0263 Mon Sep 17 00:00:00 2001 From: Andrea Merello Date: Wed, 7 May 2014 17:51:43 +0200 Subject: [PATCH] rtl8187: report mac80211 short preamble RX flag This patch make it possible to mac80211 to know whether a frame has been received with short preamble. It simply checks for the "splcp" flag in the RX status descriptor, and eventually set RX_FLAG_SHORTPRE in mac80211 rx status structure. Signed-off-by: Andrea Merello Signed-off-by: John W.
