mac80211: Fix scan_ies_len to include DS Params
Commit 651b52254fc061f02d965524e71de4333a009a5a added DS Parameter Set information into Probe Request frames that are transmitted on 2.4 GHz band, but it failed to increment local->scan_ies_len to cover this new information. This variable needs to be updated to match the maximum IE data length so that the extra buffer need gets reduced from the driver limit. Signed-off-by: Jouni Malinen <j@w1.fi> Signed-off-by: John W.
