AF_XDP on XL710 not binding in zero-copy mode

[jvr59620]

Hello,

I have an intel XL710 ethernet card running i40e driver version 2.23.17 on kernel 5.19.0-21-generic.  The firmware version on the card is  6.01 0x800035da 1.1747.0

I am trying to bind AF_XDP sockets in zero-copy mode which should be supported from what I have read. When I try to bind the sockets with zero-copy mode specified, I get an errno 95, operation not supported. Is binding in zero-copy mode not possible with this specific card and driver combo?
