From 5273c2748cbe48ad1fdc19d5f3026b3f10fa5057 Mon Sep 17 00:00:00 2001 From: Michael Brown Date: Wed, 1 Dec 2010 18:46:50 +0000 Subject: [vlan] Expose vlan_find() to network card drivers Some network cards automatically strip the VLAN header, providing the VLAN tag via a side channel such as a completion queue entry. These cards need to be able to report receive completions directly against the relevant VLAN device.
