* [patch net-next-2.6 00/47] vlan cleanup
From: Jiri Pirko @ 2011-07-20 14:54 UTC (permalink / raw)
  To: netdev; +Cc: davem, shemminger, eric.dumazet, greearb, mirqus

This patchset converts several drivers to new vlan model.
Also kills several vlan helpers:
lro_vlan_hwaccel_receive_skb
lro_vlan_hwaccel_receive_frags
__vlan_hwaccel_rx
vlan_hwaccel_rx
vlan_hwaccel_receive_skb
vlan_gro_frags
vlan_gro_receive

Removes ndo_vlan_rx_register

note gianfar patch is dependent on "[PATCH] gianfar: rx parser"

* [patch net-next-2.6 03/47] vlan: introduce __vlan_find_dev_deep()
From: Jiri Pirko @ 2011-07-20 14:54 UTC (permalink / raw)
  To: netdev; +Cc: davem, shemminger, eric.dumazet, greearb, mirqus
In-Reply-To: <1311173689-17419-1-git-send-email-jpirko@redhat.com>

Since vlan_group_get_device and vlan_group is not going to be accessible
from device drivers, introduce function which substitutes it.

* [patch net-next-2.6 01/47] gianfar: rx parser
From: Jiri Pirko @ 2011-07-20 14:54 UTC (permalink / raw)
  To: netdev; +Cc: davem, shemminger, eric.dumazet, greearb, mirqus, Sebastian Poehn
In-Reply-To: <1311173689-17419-1-git-send-email-jpirko@redhat.com>

Only let the rx parser be enabled if it is necessary (if VLAN extraction,
IP or TCP checksumming or the rx queue filer are enabled). Otherwise
disable it.

The new routine gfar_check_rx_parser_mode should be run after every
change on this features and will enable/disable the parser as necessary.
