The intel i225 can enable services but cannot receive packets

[Snailfl]

Hi~ I have changed the code on my device, now it supports i225 electrical port, but it can only send data packets, but cannot receive data packets. My environment is self-loop. The environment is as follows: root@snail:/home/snail/v3.02# cat /etc/trex_cfg.yaml

You can see it's sent 196975266,But no package was received. I added trex_driver_igc.cpp in src/drivers/ and overwrote some virtual functions. I wonder if it's true:

continued： int CTRexExtendedDriverBase2500M::configure_rx_filter_rules(CPhyEthIF * _if) { set_rcv_all(_if, false); if ( get_is_stateless() ) { return configure_rx_filter_rules_stateless(_if); } else { return configure_rx_filter_rules_statefull(_if); } return 0; } I wonder if this acceptance rule is the cause? If yes, what should I do?

I am recently using I225 with trex, after add igc driver to trex, I also encounter the problem because the default dpdk_nic_bind.py shipped with trex does not support bind to vfio-pci.

after change the device driver to vfio-pci, I can get test passed.

Hope this may help.

@fortitudepub could you try to work in software mode?

just add --software instead of changing the dpdk filter code

@fortitudepub Hello, is it convenient to know how you get it to bind to vfio-pci on ubuntu?
