Sorry, sent too soon.  I want to add that 2048 also
seems to work for ifplugd, but since in the ifmetric
bug 2048 was too small, I also choose 4096 for ifplugd.
I'm not sure if the netlink packet size is different for
ifmetric or if it depends on other things like kernel config
or type of interface.  So I choose 4096 to be on the safe side,
since I don't have the time to properly research netlink operation.
