From aae89831df03e5282a8f5c0ee46432cfb677fc5c Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Fri, 13 Mar 2009 12:52:10 +0100 Subject: wireless: radiotap updates Radiotap was updated to include a "bad PLCP" flag and standardise the "bad FCS" flag in the "flags" rather than "RX flags" field, this patch updates Linux to that standard.
