There are a mix of function prototypes with and without extern

net: vlan: make non-hw-accel rx path similar to hw-accel
Now there are 2 paths for rx vlan frames. When rx-vlan-hw-accel is
enabled, skb is untagged by NIC, vlan_tci is set and the skb gets into
vlan code in __netif_receive_skb - vlan_hwaccel_do_receive.
For non-rx-vlan-hw-accel however, tagged skb goes thru whole
__netif_receive_skb, it's untagged in ptype_base hander and reinjected
This incosistency is fixed by this patch. Vlan untagging happens early in
__netif_receive_skb so the rest of code (ptype_all handlers, rx_handlers)
see the skb like it was untagged by hw.

net: add a core netdev->rx_dropped counter
In various situations, a device provides a packet to our stack and we
drop it before it enters protocol stack :
- softnet backlog full (accounted in /proc/net/softnet_stat)
- bad vlan tag (not accounted)
- unknown/unregistered protocol (not accounted)
We can handle a per-device counter of such dropped frames at core level,
and automatically adds it to the device provided stats (rx_dropped), so
that standard tools can be used (ifconfig, ip link, cat /proc/net/dev)
This is a generalization of commit 8990f468a (net: rx_dropped
accounting), thus reverting it.

vlan: allow null VLAN ID to be used
We currently use a 16 bit field (vlan_tci) to store VLAN ID/PRIO on a skb.
Null value is used as a special value, meaning vlan tagging not enabled.
This forbids use of null vlan ID.
As pointed by David, some drivers use the 3 high order bits (PRIO)
As VLAN ID is 12 bits, we can use the remaining bit (CFI) as a flag, and
allow null VLAN ID.
In case future code really wants to use VLAN_CFI_MASK, we'll have to use
a bit outside of vlan_tci.
#define VLAN_PRIO_MASK 0xe000 /* Priority Code Point */
#define VLAN_PRIO_SHIFT 13
#define VLAN_CFI_MASK 0x1000 /* Canonical Format Indicator */
#define VLAN_TAG_PRESENT VLAN_CFI_MASK

By default GVRP is disabled because we only support the applicant-only

determine that, the user is responsible for enabling it.
The code is pretty small and low impact, its wrapped in a config

[VLAN]: Simplify vlan unregistration
Keep track of the number of VLAN devices in a vlan group. This allows
to have the caller sense when the group is going to be destroyed and
stop using it, which in turn allows to remove the wrapper around
unregister_vlan_dev for the NETDEV_UNREGISTER notifier and avoid
iterating over all possible VLAN ids whenever a device in unregistered.
Also fix what looks like a use-after-free (but is actually safe since
we're holding the RTNL), the real_dev reference should not be dropped
while we still use it.

[VLAN]: Clean up debugging and printks
- use pr_* functions and common prefix for non-device related messages
- remove VLAN_ printk levels
- kill lots of useless debugging statements
- remove a few unnecessary printks like for double VID registration (already
returns -EEXIST) and kill of a number of unnecessary checks in
vlan_proc_{add,rem}_dev() that are already performed by the caller

[VLAN]: Fix promiscous/allmulti synchronization races
The set_multicast_list function may be called without holding the rtnl
mutex, resulting in races when changing the underlying device's promiscous
and allmulti state. Use the change_rx_mode hook, which is always invoked
under the rtnl.

Patrick McHardy <kaber@trash.net> |
[VLAN]: Fix MAC address handling
The VLAN MAC address handling is broken in multiple ways. When the address
differs when setting it, the real device is put in promiscous mode twice,
but never taken out again. Additionally it doesn't resync when the real
device's address is changed and needlessly puts it in promiscous mode when
the vlan device is still down.
Fix by moving address handling to vlan_dev_open/vlan_dev_stop and properly
deal with address changes in the device notifier. Also switch to
dev_unicast_add (which needs the exact same handling).
Since the set_mac_address handler is identical to the generic ethernet one
with these changes, kill it and use ether_setup().

[VLAN]: Convert name-based configuration functions to struct netdevice *
Move the device lookup and checks to the ioctl handler under the RTNL and
change all name-based interfaces to take a struct net_device * instead.
This allows to use them from a netlink interface, which identifies devices
based on ifindex not name. It also avoids races between the ioctl interface
and the (upcoming) netlink interface since now all changes happen under the
RTNL.
As a nice side effect this greatly simplifies error handling in the helper
functions and fixes a number of incorrect error codes like -EINVAL for
device not found.

Bonding just wants the device before the skb_bond()

Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
