Re: No link between X520-DA2 and Netgear GS752TXS using Direct Attach
I agree that this doesn't seem like a simple driver problem, but I know there were some changes related to some features implemented in the SFP+ modules of some cables that can affect the timing. So a...

I didn't see anything about SR-IOV in lspci output, but I believe the I350 is "SR-IOV Capable" (whatever that means).

View ArticleRe: How to disable Linux igb driver anti-spoofing
Thanks Michael, Then I assume it only showed 4 Intel I350 ports. This means that SR-IOV is not active and it also means that there is no possible way that any of our anti-spoofing technology is...

We were able to reproduce your issue. Both with SR-IOV and with plain ports. My expert came back with this:This behavior has to do with subnet mask, Linux network stack and Linux routing. Basically,...

That makes it a bit tougher, but not impossible. The tracking # of the EEPROM is stored in words 0x2D and 0x2E. You can use ethtool to dump these words: ethtool –e vmnic4 offset 2d length 1...

I absolutely agree with you that an option ROM is needed. Does Intel offer such a thinking for their devices?? According to libvirt documentation, there is a way to load a option ROM for the device...

Intel does have option ROMS to allow the devices to boot via PXE, iSCSI Boot or FCoE Boot. However as noted before, this is not avaialble via a SR-IOV VF. While libvirt has a mechansim by which you...
