This patch adds a new mount option to specify protocol version.
With this option it is possible to use "-o version=" switch to
specify 9P protocol version to use. Valid options for version
are:

This is needed for supporting multiple mount points.
We can find out the device names to be used with mount by checking
/sys/devices/virtio-pci/virtio*/device file
if the device file have value 9 then the specific virtio device can
be used for mounting.ex:
#cat /sys/devices/virtio-pci/virtio1/device
9now we can mount using
# mount -t 9p -o trans=virtio virtio1 /mnt/Signed-off-by: Aneesh Kumar K.V

NETIF_F_NTUPLE flag setting introduced a bug: non-ntuple flags
like LRO may be successfully set, before ioctl(2) returns failure
to userspace.The set-flags operation should be all-or-none, rather than leaving
things in an inconsistent state prior to reporting failure to
userspace.Signed-off-by: Jeff Garzik

The Inode field in /proc/net/{tcp,udp,packet,raw,...} is useful to know the types of
file descriptors associated to a process. Actually lsof utility uses the field.
Unfortunately, unlike /proc/net/{tcp,udp,packet,raw,...}, /proc/net/netlink doesn't have the field.
This patch adds the field to /proc/net/netlink.Signed-off-by: Masatake YAMATO

This patch allows the user to the IGMP parameters related to the
snooping function of the bridge. This includes various time
values and retransmission limits.Signed-off-by: Herbert Xu
Signed-off-by: David S. Miller -
This patch allows the user to control the hash elasticity/max
parameters. The elasticity setting does not take effect until
the next new multicast group is added. At which point it is
checked and if after rehashing it still can't be satisfied then
snooping will be disabled.The max setting on the other hand takes effect immediately. It
must be a power of two and cannot be set to a value less than the
current number of multicast group entries. This is the only way
to shrink the multicast hash.Signed-off-by: Herbert Xu
Signed-off-by: David S. Miller -
This patch allows the user to disable IGMP snooping completely
through a sysfs toggle. It also allows the user to reenable
snooping when it has been automatically disabled due to hash
collisions. If the collisions have not been resolved however
the system will refuse to reenable snooping.Signed-off-by: Herbert Xu
Signed-off-by: David S. Miller -
This patch allows the user to forcibly enable/disable ports as
having multicast routers attached. A port with a multicast router
will receive all multicast traffic.The value 0 disables it completely. The default is 1 which lets
the system automatically detect the presence of routers (currently
this is limited to picking up queries), and 2 means that the port
will always receive all multicast traffic.Signed-off-by: Herbert Xu

This patch finally hooks up the multicast snooping module to the
data path. In particular, all multicast packets passing through
the bridge are fed into the module and switched by it.Signed-off-by: Herbert Xu

This patch hooks up the bridge start/stop and add/delete/disable

This patch adds code to perform selective multicast forwarding.
We forward multicast traffic to a set of ports plus all multicast
router ports. In order to avoid duplications among these two
sets of ports, we order all ports by the numeric value of their
pointers. The two lists are then walked in lock-step to eliminate
duplicates.Signed-off-by: Herbert Xu
Signed-off-by: David S. Miller -
This patch adds the core functionality of IGMP snooping support
without actually hooking it up. So this patch should be a no-op
as far as the bridge's external behaviour is concerned.All the new code and data is controlled by the Kconfig option
BRIDGE_IGMP_SNOOPING. A run-time toggle is also available.The multicast switching is done using an hash table that is
lockless on the read-side through RCU. On the write-side the
new multicast_lock is used for all operations. The hash table
supports dynamic growth/rehashing.The hash table will be rehashed if any chain length exceeds a
preset limit. If rehashing does not reduce the maximum chain
length then snooping will be disabled.These features may be added in future (in no particular order):
* IGMPv3 source support
* Non-querier router detection
* IPv6Signed-off-by: Herbert Xu

This patch moves the main loop body in br_flood into the function
may_deliver. The code that clones an skb and delivers it is moved

function.Signed-off-by: Herbert Xu

this patch makes BR_INPUT_SKB_CB available on the xmit path so

Signed-off-by: David S. Miller -
When the packet is delivered to the local bridge device we may
end up cloning it unnecessarily if no bridge port can receive
the packet in br_flood.This patch avoids this by moving the skb_clone into br_flood.

This patch allows tail-call on the call to br_pass_frame_up
in br_handle_frame_finish. This is now possible because of the
previous patch to call br_pass_frame_up last.Signed-off-by: Herbert Xu
Signed-off-by: David S. Miller -
At the moment we deliver to the local bridge port via the function
br_pass_frame_up before all other ports. There is no requirement
for this.For the purpose of IGMP snooping, it would be more convenient if
we did the local port last. Therefore this patch rearranges the
bridge input processing so that the local bridge port gets to see
the packet last (if at all).Signed-off-by: Herbert Xu

Author: Patrick McHardy
Date: Tue Feb 23 20:41:30 2010 +0100Support specifying the initial device flags when creating a device though
rtnl_link. Devices allocated by rtnl_create_link() are marked as INITIALIZING
in order to surpress netlink registration notifications. To complete setup,
rtnl_configure_link() must be called, which performs the device flag changes
and invokes the deferred notifiers if everything went well.Two examples:

Split dev_change_flags() into two functions: __dev_change_flags() to
perform the actual changes and __dev_notify_flags() to invoke netdevice
notifiers. This will be used by rtnl_link to defer netlink notifications
until the device has been fully configured.This changes ordering of some operations, in particular:
- netlink notifications are sent after all changes have been performed.
As a side effect this surpresses one unnecessary netlink message when
the IFF_UP and other flags are changed simultaneously.- The NETDEV_UP/NETDEV_DOWN and NETDEV_CHANGE notifiers are invoked
after all changes have been performed. Their relative is unchanged.- net_dmaengine_put() is invoked before the NETDEV_DOWN notifier instead
of afterwards. This should not make any difference since both RX and TX
are already shut down at this point.Signed-off-by: Patrick McHardy

In order to support specifying device flags during device creation,
we must be able to roll back device registration in case setting the
flags fails without sending any notifications related to the device
to userspace.This patch changes rollback_registered_many() and register_netdevice()
to manually send netlink notifications for devices not handled by
rtnl_link and allows to defer notifications for devices handled by
rtnl_link until setup is complete.Signed-off-by: Patrick McHardy
