Hi, XDP does not allow jumbo frames due to the requirement of frameSize < pageSize. I'm also aware of the ongoing work related to scatter-gather (multi-buffers) to support jumbo frames with XDP. I'm wondering if jumbo frames can be more simply supported by using AF_XDP with huge pages (instead of multi-buffers)? If so, are jumbo frames supported in both Rx and Tx directions? I assume this support is likely driver specific? Any info on using huge pages to support jumbo frames is appreciated. Thanks in advance, Srivats
