Get it while it's hot:

	kernel.org:/pub/scm/linux/kernel/git/davem/net-2.6.23.git

We have the qdisc_restart cleanup from Jama, some TIPC work
from Allan Stephens and co., and Patrick's rtnl_link work.

Also we have the removal of that multipath cached crap, and
eth_copy_and_sum() which hasn't summed anything in nearly
a decade.

So go fetch a double double, sit back, and enjoy.

Linux Networking.  Always Fresh!

I hope this still gives me the chance to submit updated patches
since I've changed a few things since the last submission and
a single incremental update would mix things that don't really
belong together.

BTW, I'm back from my trip, I'll work through all the comments
regarding these patches now.

No problem, I can yank out the current set and put your new
stuff in.

Thanks. I'll send you an update once we've worked out the
IFLA_PARTNER thing.

[PATCH] mac80211: Add support for SIOCGIWRATE ioctl to provide rate information

[John W. Linville]

From: Larry Finger <Larry.Finger@lwfinger.net>

At present, transmission rate information for mac80211 is available only
if verbose debugging is turned on, and then only in the logs. This patch
implements the SIOCGIWRATE ioctl, which adds the current transmission rate to
the output of iwconfig.

[PATCH] mac80211: Set low initial rate in rc80211_simple

[John W. Linville]

From: Larry Finger <Larry.Finger@lwfinger.net>

The initial rate for STA's using rc80211_simple is set to the last
rate in the rate table. For situations for which the signal is weak,
the rate may be too high for authentication and association. Although
the rc80211_simple module will adjust the speed, the response may not
be fast enough for a successful connection. This modification sets the
initial rate to the lowest supported value.
