Hi, all I have a 10G NIC card with fiber interface, this NIC is drived by a private os with l2 rxonly forwarding function, and I want to test this NIC could sent out PAUSE frame. host client +--------+ +------------+ | | fiber | 10G NIC | | NIC | <===> | l2fwd | | | | rxonly | +--------+ +------------+ If host send packet faster than client could receive, client 10G NIC should send out PAUSE frame, and use "ethtool -a eth0" on host to show any PAUSE frame received. How could I do this without any faster NIC card than 10G? thanks bill _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
