Description of problem:
I'm, getting this error on AWS/ROSA nodes when I try to create a ingress firewall rule
2024-01-24T19:58:35Z INFO controllers.IngressNodeFirewall Comparing currently managed interfaces against list of XDP interfaces on system {"e.managedInterfaces": {}} 152024-01-24T19:58:35Z INFO controllers.IngressNodeFirewall Attaching firewall interface {"intf": "ens5"} 162024-01-24T19:58:35Z ERROR controllers.IngressNodeFirewall Fail to attach ingress firewall prog {"error": "could not attach XDP program: create link: invalid argument", "errorCauses": [{"error": "could not attach XDP program: create link: invalid argument"}]} 17github.com/openshift/ingress-node-firewall/pkg/ebpfsyncer.(*ebpfSingleton).attachNewInterfaces.func2 18/go/src/github.com/openshift/ingress-node-firewall/pkg/ebpfsyncer/ebpfsyncer.go:202 19k8s.io/client-go/util/retry.OnError.func1
apparently this is due to the wrong MTU being set:
[ 448.622275] ena 0000:00:05.0 ens5: Failed to set xdp program, the current MTU (9001) is larger than the maximum allowed MTU (3498) while xdp is on
on the ens5 interface
