Bug ID: 461
Summary: i40evf link status is always down with the Intel XL710
driver
Product: DPDK
Version: 20.02
Hardware: x86
OS: Linux
Status: UNCONFIRMED
Severity: critical
Priority: Normal
Component: ethdev
Assignee: dev@dpdk.org
Reporter: li_hong...@nokia-sbell.com
Target Milestone: ---
When host uses i40e-2.10.19.82 driver for XL710 nic , in container the link
status is always down when XL710 VF nic uses dpdk i40evf pmd driver.
from code analysis, i40e-2.10.19.82 driver will convert link speed type
(I40E_LINK_SPEED_XXX) to mbs type (SPEED_XXX), but i40evf_dev_link_update()
only support I40E_LINK_SPEED_XXX and regard SPEED_XXX as invalid type.
default:
new_link.link_speed = ETH_SPEED_NUM_NONE;
break;
}
/* full duplex only */
new_link.link_duplex = ETH_LINK_FULL_DUPLEX;
new_link.link_status = vf->link_up &&
new_link.link_speed != ETH_SPEED_NUM_NONE
? ETH_LINK_UP
: ETH_LINK_DOWN;
