Hi all, I have two HP DL145 G1 machines, running centos4 (2.6.9-22.0.2.ELsmp).

If the VIRTIO_NET_F_GUEST_CSUM virtio feature is available, the guest does not have to calculate the checksums on all received packets. This is pretty much the same feature as RX checksum offloading on real network cards, so the virtio-net driver should report this by setting the NETIF_F_RXCSUM flag. When the user now runs "ethtool -k", he or she can see whether the virtio-net interface

I finally got a 10G card that is recognized by FreeBSD (9.1-stable): ... ix0: <Intel(R) PRO/10GbE PCI-Express Network Driver, Version - 2.4.8> port 0xecc0-0xecdf mem 0xd9e80000-0xd9efffff,0xd9ff8000-0xd9ffbfff irq 40 at device 0.0 on pci4 ix0: Using MSIX interrupts with 9 vectors ix0: RX Descriptors exceed system mbuf max, using default instead! ix0: Ethernet address: 90:e2:ba:29:c0:54

Hi list, since we activated 10gbe on ixgbe cards + jumbo frames(9k) on 9.0 and now on 9.1 we recognize that after a random period of time, sometimes a week, sometimes only a day, the system doesn't send any packets out. The phenomenon is that you can't login via ssh, nfs and istgt is not operative. Yet you can login on the console and execute commands. A clean shutdown isn't possible

Hi I installed the following driver. http://www.f.csce.kyushu-u.ac.jp/~shigeaki//software/freebsd-nfe.html Before I had the nve driver which was unstable on this server and on a prior server in both cases causing either spontaneous reboot or just a crash when under load. So far touchwood the nfe driver has stayed up and running at almost 3 days uptime and has had some stress. I know the driver

From: Tonghao Zhang <xiangxia.m.yue at gmail.com> Open vSwitch and Linux bridge will disable LRO of the interface when this interface added to them. Now when disable the LRO, the virtio-net csum is disable too. That drops the forwarding performance. Fixes: e59ff2c49ae1 ("virtio-net: disable guest csum during XDP set") Cc: Michael S.
