Hi all,

Does anyone know if extended tag is supported by Mellanox ConnectX-3 ? and if so, how to enable it ?

In Mellanox' DPDK QSG the max read request is set to 4k using setpci and register 68.w. I can't seem to find anything related to extended tag, however. In DPDK docs other address are reported which I assume are for i40e devices. Lastly, using the option in the config file does not seem to yield any difference - perhaps because it only applies to igb_uio ?

Regards,
Jesper
