Hi,
I'm testing forwarding over
em0 at pci7 dev 0 function 0 "Intel 82576" rev 0x01, msix, 4 queues,
em1 at pci7 dev 0 function 1 "Intel 82576" rev 0x01, msix, 4 queues,
em2 at pci8 dev 0 function 0 "Intel I210" rev 0x03, msix, 4 queues,
em3 at pci9 dev 0 function 0 "Intel I210" rev 0x03, msix, 4 queues,
em4 at pci12 dev 0 function 0 "Intel I350" rev 0x01, msix, 4 queues,
em5 at pci12 dev 0 function 1 "Intel I350" rev 0x01, msix, 4 queues,
and it seems that plain forwarding works as expected.
I'm sending traffic from em0 to em1, from em2 to em3 and from em4 to
em5, em6 is for ssh ...
