Hi Chris, I just remembered that we had a problem with I350 regarding VLAN connectivity between VFs. We resolved the issue lately. Did you use the latest igbvf driver on sourceforge? ver 2.0.4 is available.
Thanks, Lior. -----Original Message----- From: Levy, Lior [mailto:lior.l...@intel.com] Sent: Sunday, November 04, 2012 11:14 AM To: Chris Friesen; e1000-devel@lists.sourceforge.net; Kirsher, Jeffrey T; Brandeburg, Jesse; Allan, Bruce W; Wyborny, Carolyn; Skidmore, Donald C; Rose, Gregory V; Waskiewicz Jr, Peter P; Duyck, Alexander H; Ronciak, John Subject: Re: [E1000-devel] BUG? strange behaviour with vlans and virtual functions on i350 Hi Chris, This functionality is supported by our HW. The issue might happen due to anti-spoofing feature which blocks VLAN traffic which is not recognized by the HW. Please check the message log in the hypervisor. You might see a spoof event generated. Something like: "igb: ethX: igb_spoof_check: Spoof event(s) detected on VF 0" If so, you should turn off the anti-spoofing mechanism using 'ip' tool. Try this command before transmitting VLAN traffic: 'ip link set <ethx> vf <n> spoofchk off' Thanks, Lior. -----Original Message----- From: Chris Friesen [mailto:chris.frie...@genband.com] Sent: Friday, November 02, 2012 7:40 PM To: e1000-devel@lists.sourceforge.net; Kirsher, Jeffrey T; Brandeburg, Jesse; Allan, Bruce W; Wyborny, Carolyn; Skidmore, Donald C; Rose, Gregory V; Waskiewicz Jr, Peter P; Duyck, Alexander H; Ronciak, John Subject: [E1000-devel] BUG? strange behaviour with vlans and virtual functions on i350 Hi, We have a number of i350 devices running the 3.3.6 driver on a 2.6.34 kernel. We have multiple VMs, each of which has a pair of VFs (from different PFs) bonded together for redundancy. Normal communication works fine, but when we throw vlans into the mix things get a little haywire. We can send vlan-tagged packets from a different system and they are received in the VMs just fine. However, if we try to send vlan-tagged packets from one VM to the other the packets seem to get dropped. Looking at the datasheet it appears that the hardware should support this. Am I missing something? On both VMs the vlan config is the same: [root@ ~]# cat /proc/net/vlan/config VLAN Dev name | VLAN ID Name-Type: VLAN_NAME_TYPE_RAW_PLUS_VID_NO_PAD bond0.42 | 42 | bond0 "ifconfig -a" gives this for the device in question: bond0.42 Link encap:Ethernet HWaddr 02:A0:B0:00:0D:01 inet addr:192.168.12.213 Bcast:192.168.12.223 Mask:255.255.255.240 inet6 addr: fe80::a0:b0ff:fe00:d01/64 Scope:Link UP BROADCAST RUNNING MASTER MULTICAST MTU:1500 Metric:1 RX packets:1127 errors:0 dropped:0 overruns:0 frame:0 TX packets:993 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:85606 (83.5 KiB) TX bytes:124878 (121.9 KiB) Any help you can provide would be appreciated.
