11dc1f36a6 [BRIDGE]: netlink interface for link management
Add basic netlink support to the Ethernet bridge. Including:
 * dump interfaces in bridges
 * monitor link status changes
 * change state of bridge port

For some demo programs see:
	http://developer.osdl.org/shemminger/prototypes/brnl.tar.gz

These are to allow building a daemon that does alternative
implementations of Spanning Tree Protocol.

d32439c0d4 [BRIDGE]: port timer initialization
Initialize the STP timers for a port when it is created,
rather than when it is enabled. This will prevent future race conditions
where timer gets started before port is enabled.

78872ccb68 [BRIDGE]: Fix deadlock in br_stp_disable_bridge
Looks like somebody forgot to use the _bh spin_lock variant. We ran into a 
deadlock where br->hello_timer expired while br_stp_disable_br() walked 
br->port_list.

554c9a8ec3 [BRIDGE]: Fix faulty check in br_stp_recalculate_bridge_id()
One of the conversions from memcmp to compare_ether_addr is incorrect.
We need to do relative comparison to determine min MAC address to
use in bridge id.

4505a3ef72 [BRIDGE]: allow setting hardware address of bridge pseudo-dev
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.

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!
