Hello,
I'll update the code.
Thank you.

Hi Gregory,
I think so. For example, In kernel driver, you can find there’s a message
that’s used for PF to notify VF when the link state changes.

Hello,
In that case if I need reliable link state detection
the only option is PF link verification.
Is it so ?
Thank you.

Hi Gregory,
Yes, I remember i40e kernel driver has the watchdog too. I guess maybe all the
NICs’ kernel driver has the similar mechanism. Not sure as I haven’t checked ☺

Hello,
What about i40e VF PMD ?
Does it have reliable link state monitoring ?
Thank you.

Hi Gregory,
The mechanism is different. Kernel driver has a watchdog to check the link
state periodically. So, it can reset the link automatically.

Hello,
After the revert, my environment reproduced link up detection failure almost
immediately
With the patch the fault is rare.

Hello,
In this case I would expect ixgbe VF bound to kernel driver
also fail on link up detection
In my tests, VFs bound to kernel drivers operate correctly.

Hi Gregory,
After you turned the port donw/up, PF will re-init the VF's registers. So, VF
cannot work correctly. That's why you can know link down but not link up and
have to reset the process.

Hello,
In my tests DPDK-17.05.0 process queries link state with rte_eth_link_get()
each 50 msec
during 5-20 MB/sec IOs flow.
I turn Ethernet switch port down and up and check IXGBE VF PMD reaction to link
state changes.
VF PMD correctly recognize link down events but may miss link up.
