: net-2.6.23 tree available

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.

Dave,

Here are a few mac80211 patches appropriate for 2.6.23.

Individual patches to follow, or you can pull at your leisure...

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.

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.
