Hi,
I am having trouble with restarting a HW port allocated to DPDK.
I am running the DPDK version: 21.08.0 and Ubuntu 20.04.3 LTS.
The driver is : net_e100igb
After I start the port with no issues I try to call rte_eth_dev_stop to
stop it.
When I am ready I call rte_eth_dev_start to start it again an I get the
following message:
EAL: Error disabling MSI-X interrupts for fd 46.
I am not sure what this error is coming from and what it causes.
I found little information online. If someone could explain, I would really
appreciate it.
This is a copy print on setup with no issues:
