[PATCH v2 00/14] Move vlan acceleration into networking core.

[Jesse Gross <jesse@nicira.com>]

Hardware vlan acceleration behaves fairly differently from other types of
offloading, which limits its usefulness.  This patch series aims to bring
it more in line with other common forms of acceleration, such as checksum
offloading and TSO.  In doing this it eliminates common driver bugs, increases
flexibility, and improves performance, while reducing the number of lines of
code.

The first eleven patches can be applied immediately, while the last three need
to wait until all drivers that support vlan acceleration are updated.  If
people agree that this patch set makes sense I will go ahead and switch over
the dozen or so drivers that would need to change.

Changes since v1:
 * Break apart patches and use temporary variables for better readibility.
 * Use rcu_dereference_rtnl() in vlan_find_dev().
 * Restructure netif_needs_gso() for better common case performance.
 * Make ebtables consistently use the outer vlan tag if two are present.
 * Drop check for vlan group on transmit in all drivers.
 * Send vlan traffic through __netif_receive_skb both tagged and untagged for
   consistent results between accelerated and non-acclerated traffic.
 * Add support for Ethtool.
 * Enable vlan accleration on bridge devices.
 * Convert bnx2x driver.
