From b0e380b1d8a8e0aca215df97702f99815f05c094 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Tue, 10 Apr 2007 21:21:55 -0700 Subject: [SK_BUFF]: unions of just one member don't get anything done, kill them Renaming skb->h to skb->transport_header, skb->nh to skb->network_header and skb->mac to skb->mac_header, to match the names of the associated helpers (skb[_[re]set]_{transport,network,mac}_header).
