65c501a093 ifupdown: 'prio' should have been 'metric' in static_up and static_up6
When a static interface with explicit gateway and metric in /etc/network/interfaces
is enabled using 'ifup', and further, the BusyBox 'ip' applet is enabled, the
following error message appears at the console (and no default route is added):

ip: either "to" is duplicate, or "prio" is garbage

Tracing ifup reveals that it is attempting to run the following shell command:

ip route add default via <GW> dev <DEVICE> prio <METRIC>

'ip' does not understand the 'prio' argument, causing this error. With 'metric',
it works fine.

6ca03f2dd8 ifupdown: correct ifstate update during 'ifup -a'. Closes 6212
When 'if -a' runs into an failure on an interface all further
interfaces won't be correctly updated in ifstate. This patch
inserts a new variable that only tracks the current interfaces
failure so that the write to ifstate can rely on this and not
the one for the functions return value.

Fixes https://bugs.busybox.net/show_bug.cgi?id=6212

fe8390e0fe ifupdown: support 'link' address family

5e34ff29bc *: mass renaming of USE_XXXX to IF_XXXX
and SKIP_XXXX to IF_NOT_XXXX - the second one was especially
badly named. It was not skipping anything!

142c5cb2a2 ifupdown.c: allow options to udhcpc to be configurable from .config
This allows more control over options that are passed to udhcpc
that are not configurable via /etc/network/interfaces.

Example: rather than quit when an initial lease isn't found,
you could use "--background" so that udhcpc keeps running and
continually attempts to get an ip.  That way, when you plug in
the ethernet after powering on the device, you'll still get an ip.
