I have the xensource 3.1.0 x86_64 tarball installed over a RHEL5 clone distribution. The "ethtool" utility only returns the following information: [root@fermigrid5 etc]# ethtool eth0 Settings for eth0: Link detected: yes [root@fermigrid5 etc]# Since I have no vanilla-installed rhel5 machines with which to compare, I am not sure if I am dealing with a bug in the ethtool (whose ou...

Thanks for the feedback. I thought it's handy to be able to check stats like this in ethtool as well. Some drivers like ixgbe and mlx5 do similar thing. I can remove these duplicate stats (unless anyone has objection). -- Toshiaki Makita

From: Nikolay Aleksandrov <nikolay at cumulusnetworks.com> This patch allows the user to set and retrieve speed and duplex of the virtio_net device via ethtool. Having this functionality is very helpful for simulating different environments and also enables the virtio_net device to participate in operations where proper speed and duplex are required (e.g. currently bonding lacp mode requires full duplex). Custom speed and duplex are not allowed, the user-...

in dom0, how does one get and set the link information for a NIC? In a non-xen kernel, we could get this info by simply running: # ethtool eth0 Settings for eth0: Supported ports: [ TP MII ] Supported link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full Supports auto-negotiation: Yes Advertised link modes: 10baseT/Half 10baseT/Full...

I want to check the speed like features of my Ethernet in dom0 and domUs. But in virtualized environment it gives strange output why is that so? how to check it otherwise? Non-virtualized FC11 [root@fasiha home]# ethtool eth0 Settings for eth0:     Supported ports: [ TP ]     Supported link modes:   10baseT/Half 10baseT/Full                             100baseT/Half 100baseT/Full                             1000baseT/Half 1000baseT/Full     Supports auto-negotiation: Yes     Advertised link modes:  10baseT/Half...

...llo, Just did a fresh install of xen-4.0 and using the 2.6.31.13 dom0 kernel. I have 6 linux debian guests running, and on my host console i am getting these errors rolling pretty constantly. "Attempting to checksum a non-TCP/UDP packet, dropping a protocol 1 packet" I tried doing the ethtool -K eth0 tx off and same thing on peth0, using bridged mode for network config. Any tips? Google is failing me, im not sure what to even search for other than "xen Attempting to checksum a non-TCP/UDP packet". Im wondering if this has something to do with why my guests were seeming to ha...

We've just moved one a new server from our sever room, where I built it, to the datacenter. We want to force autoneg off, and tell it gigabit and full duplex. Using ethtool, I get no errors setting the speed or duplex. HOWEVER, autoneg on works... and autoneg off utterly refuses to work, and gives: ethtool -s eth0 autoneg off Cannot set new settings: Invalid argument not setting autoneg We're on the most current update of CentOS (ok, last kernel, that will come...

My system is: Intel CC820 motherboard (which supports PME# wake up for wake on LAN) 3com 3C905C which also supports wake on LAN via PME# Linux 5.5 The motherboard BIOS is later than one that reports an issue with WOL and this particular network card was fixed. But when I turn off the PC (shutdown or poweroff commands or front panel button), it cannot be restarted via WOL. The network light on
