But, from TRex v2.43, TRex showed ierror from 50mbps traffic.\r\nIssue #2. And from TRex v2.44, TRex cannot send any packet to XL710 SRIOV-VF port.\r\nSee attached log file.\r\n\r\nI tested it on Suse and Ubuntu server, both server showed same issue.\r\nI tested various versions of i40e drivers, all drivers showed same issue.\r\n\r\nI assume that\r\nIssue #1. The XL710 changes in v2.43( TREX-531 and TREX-528 ) may related with the issue.\r\nIssue #2. i40e PMD change in DPDK 18.05 may related with the issue.\r\n\r\nThanks\r\n\r\nBest Regards\r\nGwangmoon\r\n\r\n[xl710-sriov-issue.log](https://github.com/cisco-system-traffic-generator/trex-core/files/2422562/xl710-sriov-issue.log)\r\n"},"comment":{"url":"https://api.github.com/repos/cisco-system-traffic-generator/trex-core/issues/comments/442039075","html_url":"https://github.com/cisco-system-traffic-generator/trex-core/issues/148#issuecomment-442039075","issue_url":"https://api.github.com/repos/cisco-system-traffic-generator/trex-core/issues/148","id":442039075,"node_id":"MDEyOklzc3VlQ29tbWVudDQ0MjAzOTA3NQ==","user":{"login":"hhaim","id":13034429,"node_id":"MDQ6VXNlcjEzMDM0NDI5","avatar_url":"https://avatars0.githubusercontent.com/u/13034429?v=4","gravatar_id":"","url":"https://api.github.com/users/hhaim","html_url":"https://github.com/hhaim","followers_url":"https://api.github.com/users/hhaim/followers","following_url":"https://api.github.com/users/hhaim/following{/other_user}","gists_url":"https://api.github.com/users/hhaim/gists{/gist_id}","starred_url":"https://api.github.com/users/hhaim/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/hhaim/subscriptions","organizations_url":"https://api.github.com/users/hhaim/orgs","repos_url":"https://api.github.com/users/hhaim/repos","events_url":"https://api.github.com/users/hhaim/events{/privacy}","received_events_url":"https://api.github.com/users/hhaim/received_events","type":"User","site_admin":false},"created_at":"2018-11-27T12:20:55Z","updated_at":"2018-11-27T12:20:55Z","author_association":"CONTRIBUTOR","body":"`--software` with 2 cores pay more tax than  one `--software -c 1` actually it almost factor 2. as in case of c=2 rx core does not work at all. \r\n\r\nJust wanted you to verify that you have this line in trex_cfg.yaml `rx_desc : 4096`  with latest branch.\r\nCould you verify it?\r\n"}}
