Aurora 64b66b connecting with 10G ethernet

We've been trying to connect a 10G ethernet source directly to an Aurora 64b66b via an SFP+ port.  The Aurora 64b66b is set up as TX/RX simplex and loopback internally.  The rate of the 10G source is 10.3125Gbps.  We are trying to read received packets from the Aurora 64b66b at the 10G source (using wireshark) but do not get any packets.

  Logically the 10G ethernet uses 64b66b protocol which is the same as Aurora, so packets should be able to flow in the link.  But the 10G ethernet source has a MAC but the Aurora does not.  Is it possible to connect the 10G ethernet source to the Aurora 64b66b and loopback in this manner?

Hope folks who have experience in this can throw some light on the issue.  Thank you for your help.

Hi,
I forgot to mention that we are using Avnet Ultrazed board and Vivado 2019.2.

Aurora is not Ethernet, so I'm pretty sure this won't work.  Just because it's also 64b/66b doesn't mean that the control characters are used the same way.  And even if they were, most 10G NICs automatically drop packets with invalid FCS fields, and I don't think Aurora is computing the same FCS as Ethernet.
