Hi,
I have a problem while trying to manage my physica= l Ethernet interface from DPDK (latest version compiled from source).
I = have a:
NIC: 0000:00:1f.6 Ethernet controller:= Intel Corporation Ethernet Connection (13) I219-LM (rev 20)

= which belongs to the list of supported NICs in DPDK.

Als= o, I have bound my NICto vfio-pci, not the kernel:

I also enabled hugepages (2G).<= br>
when I enter "sudo build/app/dpdk-test= pmd -c7 -- -i" I get:

When I enter "show port info all" in the testpmd CLI I get nothing (no ports).

When I start testpmd= with "-a 0000:00:1f.6" (the addr= ess of the ethernet NIC I want to manage from DPDK), The same happens (no p= orts).

If I try to start testpmd with "-d build/drivers/librte_net_e1000.so" (the shared libra= ry of the driver of that device), I get a crash:

I have also checked that:

and other virtualization flags enabled = (VT-x, VT-d), and the=C2=A0Secure Boot is disabled.
Also the NIC works f= ine in normal circumstances (managed by the OS kernel).

I am running Ubuntu 20.04.6 on a Dell Precision 3560 laptop (1 year o= ld).

I don't know whether this is a bug or I missed something, s= o I would appreciate any guidance. Thanks in advance

Anton
