Subject: [3/5] netdev: HH_DATA_OFF bugfix
Date: Tue, 24 May 2005 15:12:04 +0200 [thread overview]
Message-ID: <20050524151204.554f73cb@griffin.suse.cz> (raw)
In-Reply-To: <20050524150711.01632672@griffin.suse.cz>
When the hardware header size is a multiple of HH_DATA_MOD, HH_DATA_OFF()
incorrectly returns HH_DATA_MOD (instead of 0).
