Stephen Hemminger 3113e88c3c [PKT_SCHED]: vlan tag match
Provide a way to use tc filters on vlan tag even if tag is buried in
skb due to hardware acceleration.

Patrick McHardy e5dfb81518 [NET_SCHED]: Add flow classifier
Add new "flow" classifier, which is meant to extend the SFQ hashing
capabilities without hard-coding new hash functions and also allows
deterministic mappings of keys to classes, replacing some out of tree
iptables patches like IPCLASSIFY (maps IPs to classes), IPMARK (maps
IPs to marks, with fw filters to classes), ...

Some examples:

- Classic SFQ hash:

  tc filter add ... flow hash \
  	keys src,dst,proto,proto-src,proto-dst divisor 1024

- Classic SFQ hash, but using information from conntrack to work properly in
  combination with NAT:

  tc filter add ... flow hash \
  	keys nfct-src,nfct-dst,proto,nfct-proto-src,nfct-proto-dst divisor 1024

- Map destination IPs of 192.168.0.0/24 to classids 1-257:

  tc filter add ... flow map \
  	key dst addend -192.168.0.0 divisor 256

- alternatively:

  tc filter add ... flow map \
  	key dst and 0xff

- similar, but reverse ordered:

  tc filter add ... flow map \
  	key dst and 0xff xor 0xff

Perturbation is currently not supported because we can't reliable kill the
timer on destruction.

Patrick McHardy b4e9b520ca [NET_SCHED]: Add mask support to fwmark classifier
Support masking the nfmark value before the search. The mask value is
global for all filters contained in one instance. It can only be set
when a new instance is created, all filters must specify the same mask.

Linus Torvalds 1da177e4c3 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!
