Calling stop and then start calls the func= tion=C2=A0twice. Which maybe shouldn't happen... Is it a bug?=C2=A0

Hi,
I am having trouble with restarting a HW port allocated t= o 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=C2= =A0I 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: Er= ror disabling MSI-X interrupts=C2=A0for fd 46.
I am not sure what this e= rror is coming from and what it causes.
I found little information onlin= e. If someone could explain,=C2=A0I would really appreciate it.
