From 7ea49ed73c8d0d0bdf7c11fc18c61572d2d22176 Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Mon, 14 Aug 2006 17:08:36 -0700 Subject: [VLAN]: Make sure bonding packet drop checks get done in hwaccel RX path. Since __vlan_hwaccel_rx() is essentially bypassing the netif_receive_skb() call that would have occurred if we did the VLAN decapsulation in software, we are missing the skb_bond() call and the assosciated checks it does. Export those checks via an inline function, skb_bond_should_drop(), and use this in __vlan_hwaccel_rx(). Signed-off-by: David S.
