Unfortunately git isn't the greatest for saying "just give me what is on 
the remote", since each repository is an independent peer.

You need to:
* grab the latest torvalds/linux-2.6.git
* erase local netdev-2.6
* clone to create local netdev-2.6:
	URL=git//git.kernel.org/.../jgarzik/netdev-2.6
	git-clone --reference linux-2.6 $URL netdev-2.6
* that creates 'master' branch, which always equals vanilla upstream
* now create a local upstream branch:
	git checkout -b upstream master
* and finally, pull remote upstream branch into local upstream branch:
	git pull $URL upstream:upstream

Occasionally the remote 'upstream' will get "rebased", which means is 
has been completely replaced by a new linear history.  If you pull 
'upstream' after a rebase, into a local 'upstream', git will attempt to 
merge the same patches all over again, with disastrous results.

I wish there was a git option to "just make my shit look like the 
remote, dammit!"  The above is the "easiest" way I know how to do that.
