Wait for carrier before announcing IPs via GARP/NA
After setting up the interface, it might take a bit for kernel to detect carrier. If we then already send the GARP/NA packets, they are lost. Instead, wait for up to 200 msec for the interface to get carrier. This time is chosen somewhat arbitrarily. We don't want to block the process too long, but we also need to wait long enough, that kernel and driver has time to detect carrier. Also, while busy waiting, sleep with an exponential back-off time (growth factor 1.5). Fixes: c241dcb ('Send IPv4 GARP and IPv6 Unsolicited NA in "cmdAdd"') See-also: https://issues.redhat.com/browse/OCPBUGS-30549 Signed-off-by: Thomas Haller <[email protected]>
