From fe5f8e2a1c5c040209c598a28e19c55f30e1040d Mon Sep 17 00:00:00 2001 From: Zhu Yi Date: Wed, 20 Dec 2006 16:11:58 +0800 Subject: [PATCH] [PATCH] ipw2100: Fix dropping fragmented small packet problem The rx_data.header struct is ieee80211_hdr_4addr. If a wireless frame uses ieee80211_hdr_3addr header and is less than 6 bytes, it will be discarded. This is not likely going to happen for normal packets (since there is TCP, IP headers). But if fragmentation is used, there will be such small trailing packets. And they will be lost for ever. Signed-off-by: Zhu Yi Signed-off-by: John W.
