This patch modifies the patch submitted by Kou Ishizaki to make it
work on the
blade
(http://marc.theaimsgroup.com/?l=linux-netdevm=116593424505539w=2).
Unfortunately I dont have access to a Celleb so I cannot test it
there.
Thanks

The second use of rtl8169_set_speed is in the change_mtu handler which

Hi gurus,
I am testing tcp_vegas.c in Linux with the NS-2 TCP-Linux. It seems
that the ssthresh is not correctly reset in this file and the problem
might lead to very unfair behavior among Vegas flows, when some flows
exit slow start due to loss, not delay.
Please see the details at:

This patch adds improved version of enable_fiber for both the 5421 and

autonegotiation or not. This is needed for bladecenter switches where
some expect autonegotiation and some dont seem to like this at all.

Ishizaki-san,
This patch partially works on celleb but remains
following several problems.
1. It doesn't recover once an ethernet cable which is
connected to a spider_net card is unpluged.
My understanding is that you are using the LINK interrupt to detect this.
For the blade this is
We forget to call spider_net_free_rx_chain_contents which does the
actual dev_kfree_skb. New skbs are allocated from skbuff_head_cache
on each ifconfig up letting the cache grow infinitely.
