Hi gang.

commit 3326c784c9f492e988617d93f647ae0cfd4c8d09

Author: Jiri Pirko <jpirko@>
Date:   Wed Jul 20 04:54:38 2011 +0000

forcedeth: do vlan cleanup

- unify vlan and nonvlan rx path
- kill np->vlangrp and nv_vlan_rx_register
- allow to turn on/off rx vlan accel via ethtool (set_features)

This commit causes networking trouble for my nForce-based motherboard. (Details happily supplied if needed.)

I say 'partial' breakage because networking is not completely dead, just limping very slowly :)

The simplest test is to ping any host (in my LAN or on the internet, makes no difference). The replies to my ping come at very irregular intervals, ranging from normal to 5-10 seconds or so, seemingly at random AFAICT.

I'm happy to try any patches, tests, whatever, to help fix this.

Many thanks!

I'm seeing this too. Ping responses phase in and out every 10 seconds or so.

Jiri, any thoughts?

I am seeing similar here. Pings are often being dropped all together and the network is unusable. Mainboard is an ASUS M2N with NVIDIA nForce 430 MCP chipset.
