Subject: r8169: 2.6.22rc6+patches works, but 2.6.21.5 and 2.6.22rc6 without
 patches->network transfer blocking

			Hello.

The hardware involved:

Motherboard: Asus P5B
lspci:
02:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd.
RTL8111/8168B PCI Express Gigabit Ethernet
 controller (rev 01)

First the non-working scenario (2.6.21.5, 2.6.22rc6 unpatched):
During the use of network connections, we experience "network transfer
stops" during which a transfer seems to stall completely for many
seconds, after which the transfer runs as if nothing happened.

This is reproducable everytime w.
 svn co http://svnserver/svn/tree
   (hangs VERY LONG)

Now with all patches under
http://www.fr.zoreil.com/linux/kernel/2.6.x/2.6.22-rc3/r8169-20070527/

    and the single patch
http://www.fr.zoreil.com/people/francois/misc/20070619-2.6.22-rc5-r8169-test.patch

the problem is gone. Without the single patch, the problem persists.

Is there any possibility to get this fix working in 2.6.21.5? Would it
be possible to apply the single patch to 2.6.21.5 and get a working
driver? Or would it be possible to create the fixing patch for the
driver in 2.6.21.5?

		Greets,
		  Jens
