[Bug] Failed to use netmap, `nm_do_ioctl: No such file or directory`

[duskmoon314]

Describe the bug

I'm trying to use tcpreplay with netmap enabled on a Ubuntu 22.04 machine with Intel 82599ES. After building netmap (master with ixgbe:5.18.11) and tcpreplay 4.4.4, I failed to switch the network driver to netmap bypass mode because of the nm_do_ioctl: No such file or directory

It seems I cannot build netmap on Ubuntu 22.04 successfully with an older version (v11, v13) so I use the master branch. The version of ixgbe is the latest one in netmap/LINUX/final-patches that I can build successfully.

To ReproduceSteps to reproduce the behavior: 0. Clone netmap to~/Documents/netmap; Clone tcpreplay to ~/Documents/tcpreplay`

1. Build netmap with: ./configure --no-drivers=virtio_net.c --driver-suffix=-netmap --select-version=ixgbe:5.18.11 && make -j && sudo make install
2. Build tcpreplay with: ./configure --with-netmap=~/Documents/netmap && make -j && sudo make install
3. sudo tcpreplay -i enp1s0f1 --netmap dataset/202006101400.pcap
4. Get the error:

Switching network driver for enp1s0f1 to netmap bypass mode... failed!
 Switching network driver for enp1s0f1 to normal mode... 
Fatal Error: failed to open device enp1s0f1: nm_do_ioctl: No such file or directory

Expected behavior I want to use tcpreplay with netmap to send packets as in normal mode (without --netmap).

Screenshots

System (please complete the following information):

• OS: Ubuntu 22.04
• Tcpreplay Version 4.4.4.

Additional context ~I haven't figured out how to let tcpreplay show more information about the failure.~ Please give me some advice to find out how to provide more information and solve this problem.

I rebuild tcpreplay with debug output enabled. And the output is:
