From 8ce0b5892460c670b71b7a0bf96549f5e7a63d6c Mon Sep 17 00:00:00 2001 From: Zhu Yi Date: Wed, 28 Oct 2009 13:13:52 -0700 Subject: [PATCH] mac80211: make align adjustment code support paged SKB This fixed a BUG_ON in __skb_trim() when paged rx is used in iwlwifi driver. Yes, the whole mac80211 stack doesn't support paged SKB yet. But let's start the work slowly from small code snippets.
