This patch checks kmem_cache_create() error and aborts loading module
on failure.Signed-off-by: Akinobu Mita

This patchset based on work by Aji_Srinivas@emc.com provides allows
spanning tree to be controled from userspace. Like hotplug, it
uses call_usermodehelper when spanning tree is enabled so there
is no visible API change. If call to start usermode STP fails
it falls back to existing kernel STP.Signed-off-by: Stephen Hemminger

The RSTP daemon needs to be able to flush all dynamic forwarding
entries in the case of topology change.This is a temporary interface. It will change to a netlink interface
before RSTP daemon is officially released.Signed-off-by: Stephen Hemminger

Change the bridging hook to be simple function with return value
rather than modifying the skb argument. This could generate better
code and is cleaner.Signed-off-by: Stephen Hemminger

Having a work queue for checking carrier leads to lots of race issues.
Simpler to just get the cost when data structure is created and
update on change.Signed-off-by: Stephen Hemminger

Flush the forwarding table when carrier is lost. This helps for
availability because we don't want to forward to a downed device and
new packets may come in on other links.Signed-off-by: Stephen Hemminger

Add basic netlink support to the Ethernet bridge. Including:
* dump interfaces in bridges
* monitor link status changes
* change state of bridge portFor some demo programs see:
http://developer.osdl.org/shemminger/prototypes/brnl.tar.gzThese are to allow building a daemon that does alternative
implementations of Spanning Tree Protocol.Signed-off-by: Stephen Hemminger

Bridge's communicate with each other using Spanning Tree Protocol
over a standard multicast address. There are times when testing or
layering bridges over existing topologies or tunnels, when it is
useful to use alternative multicast addresses for STP packets.The 802.1d standard has some unused addresses, that can be used for this.
This patch is restrictive in that it only allows one of the possible
addresses in the standard.Signed-off-by: Stephen Hemminger

Use LLC for the receive path of Spanning Tree Protocol packets.
This allows link local multicast packets to be received by
other protocols (if they care), and uses the existing LLC
code to get STP packets back into bridge code.The bridge multicast address is also checked, so bridges using
other link local multicast addresses are ignored. This allows
for use of different multicast addresses to define separate STP
domains.Signed-off-by: Stephen Hemminger

Refactor how the bridge code interacts with kobject system.
It should still use kobjects even if not using sysfs.

Change Bridge receive path to correctly handle RCU removal of device
from bridge. Also fixes deadlock between carrier_check and del_nbp.
This replaces the previous deleted flag fix.Signed-off-by: Stephen Hemminger

This is a simpler fix for the two races in bridge device removal.
The Xen race of delif and notify is managed now by a new deleted flag.
No need for barriers or other locking because of rtnl mutex.The del_timer_sync()'s are unnecessary, because br_stp_disable_port
delete's the timers, and they will finish running before RCU callback.Signed-off-by: Stephen Hemminger

Add limited ethtool support to bridge to allow disabling
features.Note: if underlying device does not support a feature (like checksum
offload), then the bridge device won't inherit it.Signed-off-by: Stephen Hemminger

Speed of a interface may not be available until carrier
is detected in the case of autonegotiation. To get the correct value
we need to recheck speed after carrier event. But the check needs to
be done in a context that is similar to normal ethtool interface (can sleep).Also, delay check for 1ms to try avoid any carrier bounce transitions.

Some people are using bridging to hide multiple machines from an ISP
that restricts by MAC address. So in that case allow the bridge mac
address to be set to any of the existing interfaces. I don't want to
allow any arbitrary value and confuse STP.Signed-off-by: Stephen Hemminger

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!
