From 306fe9384f06d31219778cece2d3c646146e7bb6 Mon Sep 17 00:00:00 2001 From: Luciano Coelho Date: Mon, 9 May 2011 19:15:04 +0300 Subject: [PATCH] mac80211: don't drop frames where skb->len < 24 in ieee80211_scan_rx() This seems to be a leftover from the old days, when we didn't support any frames that didn't contain the full ieee802.11 header. This is not the case anymore. It does not cause problems now, because they are only dropped during scan. But when scheduled scans get merged, this would become a problem because we would drop all small frames while scheduled scan is running. To fix this, return RX_CONTINUE instead of RX_DROP_MONITOR.
