[Bug 35690] Steam network hang ups.

http://bugs.winehq.org/show_bug.cgi?id=35690

--- Comment #11 from Mike  ---
I spend all night, trying to solve this headache.

On guest (QEMU/KVM) Steam working fine.
On host - network not working (hanging to timeout for udp, lagging for tcp)

I rebuilded entire system with -O2 instead of O3 - not helped.
I reinstalled wine from binary - not helped.
I used kernel options from guest by coping .config, ofc same kernel version
(3.10.25, amd64) - no effect.

I checked ulimits and sysctl options. They almost same.

I disabled udev and all rc-services. No effect.

I changed some hardware - swaped my inet connection from ethernet to wifi.
Steam network still not working on host and perfectly working on guest.

I even mount my host wineprefix dir to guest thru smb - it's working well on
guest and not working on host.

So, what the difference between host and guest for wine? Does it uses... I
dunno, some bios/hardware features for networking?
