How can I set/query this bit (LLE(PFVMTXSW[n]), intel 82599 ) on ESX, or
any other friendlier environment like Linux?

Hi,
I'm trying to send packets from an application to it self, meaning smac

dmac.
I'm working with intel 82599 virtual function. But it seems that these
packets are lost.

Is there a software/hw limitation I'm missing here (some additional
anti-spoofing)? AFAIK modern NICs with sriov are mini switches so the hw
loopback should work, at least thats the theory.
[Liang, Cunming] You could have a check on register LLE(PFVMTXSW[n]).
Which allow an individual pool to be able to send traffic and have it
loopback to itself.

Thanks.
