Felix crashes when kube-proxy is in IPVS mode

When configuring kube-proxy to use IPVS proxy mode, with the following (soon to be released) config:

juju config kubernetes-control-plane proxy-extra-config='{mode: ipvs, ipvs: {strictARP: true}}'
juju config kubernetes-worker proxy-extra-config='{mode: ipvs, ipvs: {strictARP: true}}'

In both journalctl and in /var/log/calico/felix/current, logs can be seen with Calico's Felix service crashing repeatedly:

This is a known issue in Calico:
https://github.com/projectcalico/calico/issues/5011
https://github.com/projectcalico/calico/issues/5717

Fixed for amd64 in Calico v3.22.1. Fixed for arm64 in Calico v3.23.2 and v3.22.4. We can fix this in the Calico charm by updating Calico.
