I haven't had need to try this, but I think all you need to do is modify the
command that brings up the link. See the iproute2 command documentation,
but the "ip link set" command will take "arp off" and "dynamic off" as
options, along with several other link parameters...this (maybe combined
with a kernel /proc option or two) will probably do what you want.
# ip link help
Usage: ip link set DEVICE { up | down | arp { on | off } |
dynamic { on | off } |
multicast { on | off } | txqueuelen PACKETS |
name NEWNAME |
address LLADDR | broadcast LLADDR |
mtu MTU }
ip link show [ DEVICE ]
