Adjusts kernel ARP/neighbor table sizes for very large subnets based
on configured IPv4/IPv6 network interface netmask values. Normally executes
once on boot by
opa.service; however,
opa-arptbl-tuneup can be invoked with user discretion
for a changed subnet configuration.
Note: Must execute as
root.
