This will help me address bin/11079, "dhclient may require arp and sed".
Extract common code from flushroutes() and show(), creating
parse_show_opts().
While I'm here, make small cosmetic changes to flushroutes().
family is unset. Either the destination or interface address socket address
family value is used. This change prevents the following sort of output:
RTM_NEWADDR: address being added to iface: len 60, metric 0, flags:<UP>
sockaddrs: <NETMASK,IFA,BRD>
(0) 00.00.ff.00.00 127.0.0.1 127.0.0.1
With this change the last line becomes:
255.0.0.0 127.0.0.1 127.0.0.1
Also make sure that when using a generated inet netmask the address family
is set. With this change a generated netmask will print appropriately
when using the verbose (-v) option.
and check netmask (or prefix) length as well as the destination
address when determining if a route is a "default" or not. This means
that the output from 'route show' will no longer say:
Internet6:
Destination Gateway Flags
default localhost UG
default localhost UG
but instead
Internet6:
Destination Gateway Flags
::/104 localhost UGR
::/96 localhost UGR
which makes much more sense.
