dpdk qede pmd driver does not work in Debian Bookworm. dpdk-testpmd cannot
receive any packet due to nombuf. This happens to both kernel driver vfio-pci
and uio_pci_generic. 

However
(1) Linux kernel's qede driver works fine.
(2) The Qlogic qede card and dpdk-testpmd works in Debian Bullseye.

Here are some logs:
