Hi guys
There may have firmware dependencies, new DPDK version + old firmware version may not work. Please refer to below link to see what type of firmware has been validated with 16.11 DPDK.
http://dpdk.org/doc/guides/rel_notes/release_16_11.html#tested-nics
Then first, you need to upgrade your firmware. Then let us know if the issue is still there. Thanks!
Regards,
Helin

Hi Ivan:
I'm looking at this issue, but I can't repeat it on my environment both with X710x4 and XL710x1
Not sure if you could try below things to help narrow down this issue.
1) move i40e_dev_sync_phy_type call after i40e_set_fc call, to see if the problem still exist, since without i40e_dev_sync_phy_type, i40e_set_fc is the first place i40e_aq_get_phy_capabilities get called and we didn't see this issue before 16.11.
2) if above change works, at least we have a work around, if above still fail, please modify the parameter of i40e_aq_get_phy_capabilities in i40e_dev_sync_phy_type as below and check result.
- status = i40e_aq_get_phy_capabilities(hw, false, true, &phy_ab,
- NULL);
+ status = i40e_aq_get_phy_capabilities(hw, false, false, &phy_ab,
+ NULL);
Thank you!
Regards
Qi
