RE: [d80211] connecting to B-mode AP
The extended rates element is only needed if there are more than 8 rates to report - which is normal for G operation, but not necessary. It only exists because a particularly popular old 11b MAC codebase crashed when the normal rate element had more than 8 elements, and this hurt interoperability with early G AP implementations - so the spec was changed.

Re: e1000 Detected Tx Unit Hang
Jesse, today the server froze and was not able to see anything in the logs. Nothing at all about any error, just plain froze. Just in case, this is a different unit altogether, still the same model as the units having the Tx Unit Hang, but different memory, motherboard and CPU. The only 1 thing that is the same is the hard drive a regular IDE... The only one thing I noticed that is very weird to me at least is that in powering off the unit from the crash and rebooting it I saw some lines like this in the logs..

[ATM]: [he] he_init_one() is declared __devinit, but calls __init functions
he_init_one() is declared __devinit, but calls lots of init functions
that are marked __init. However, if CONFIG_HOTPLUG is enabled,
__devinit functions go into normal .text, which leads to
WARNING: drivers/atm/he.o - Section mismatch: reference to .init.text:
from .text between 'he_start' (at offset 0x2130) and 'he_service_tbrq'
Fix this by changing the __init functions to __devinit.

TCP LP is probably the worst one to use, because it is designed for bulk low priority applications. It also is one of the newest least tested. Right now, I would rate the choices as: Stable: reno, bic, htcp, westwood, cubic Testing: hybla, highspeed, scaleable, vegas Unstable: veno, lp The stable ones seem to be reliable and have no known issues. The testing group are only interesting for comparison, and need more tuning. The unstable group, are new and need even more testing for fairness and robustness. Without a back trace, it will be hard to find the bug in TCP LP - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html

Re: [PATCH]:[XFRM] BEET mode
The patch which introduces the BEET mode and which previously was sent to this
mailing list is valid also for
http://www.kernel.org/git/?p=linux/kernel/git/davem/net-2.6.19.git;a=summary
branch.
However there are probably some errors in attaching inline the patch to the
mail.
I retry to reattach it. In any case, if there would be some errors, the same
patch can be found at the following URL and it works just fine:
http://infrahip.hiit.fi/beet/tmp/simple-beet-ph-patch-2.6.18
For those who haven't been following this discussion, the patch introduces the
