Compiling netmap on AlmaLinux 9.5

[steven-b89]

Hi all,

When I am trying to compile Netmap to use on Almalinux 9.5 i get the following errors with the virtio_net driver which is the one i am using.
Would be helpfull is someone could put me in the right direction but I am guessing that there is a problem with the virtio_net.c file it is using provided by the distro ?
