From 98e399f82ab3a6d863d1d4a7ea48925cc91c830e Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Mon, 19 Mar 2007 15:33:04 -0700 Subject: [SK_BUFF]: Introduce skb_mac_header() For the places where we need a pointer to the mac header, it is still legal to touch skb->mac.raw directly if just adding to, subtracting from or setting it to another layer header. This one also converts some more cases to skb_reset_mac_header() that my regex missed as it had no spaces before nor after '=', ugh. Signed-off-by: Arnaldo Carvalho de Melo Signed-off-by: David S.
