[Hardy] r8169: intermediate connection problems on server

[Stefan Bader]

SRU justification:

Impact: There is a register which is only valid for r8169 chipsets but currently gets used unconditionally. Also only the lower 3bits of that register are valid.

Fix: Backport of upstream fix: http://git.kernel.org/?p=linux/kernel/git/jgarzik/netdev-2.6.git;a=commitdiff;h=523a609496dbc3897e530db2a2f27650d125ea00;hp=e93dcb11dd6468000f2f018bd887e94b074ce931

Testcase: Manual network setup with r8169 based network card sometimes gets connection problems as described below.

Reported by emgent:

The problem is that r8169 driver don't work fine in Hardy heron, some times dhclient go to sleep and do not assign real IP Address. After reboot sometimes work and sometimes not.

This issue has only be seen on ubuntu-server. This might be due to NetworkManager does some tweaks to get around this.

Stefan,

Is this fix present in the jaunty kernel?

[Steve Langasek (vorlon)]

Accepted into hardy-proposed; please test and give feedback here. Please see https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!

[Stefan Bader (smb)]

Yes, it is already included with Jaunty. The changes requested are also present in Intrepid.
