Those two spaces after tab have no effect, and always a nuisance when editing.

f560422fa0 Big cleanup in config help and description
Redundant help texts (one which only repeats the description)
are deleted.

Descriptions and help texts are trimmed.

Some config options are moved, even across menus.

No config option _names_ are changed.

100aea8486 Remove FEATURE_IFUPDOWN_IP_BUILTIN and FEATURE_IFUPDOWN_IFCONFIG_BUILTIN

3720a61daf ifupdown: rewrite state file atomically
By user's request.
Decided to not use fcntl(F_SETLKW) in lieu of problems with locking
on networked filesystems. The existence of /var/run/ifstate.new
is treated as a write lock. rename() provides atomicity.

92d98f0612 ifupdown: when flushing addresses with "ip", add label %label%
User report:

or our board we setup eth0:0 on a 10.10.10.x/29 netwrok.

The problem is ip addr flush dev eth0:0 removes all ip addresses from
eth0.  You can see this if you run
ip -stat -stat addr flush dev eth0:0

2: eth0    inet 172.27.105.10/22 brd 172.27.107.255 scope global eth0
       valid_lft forever preferred_lft forever
2: eth0    inet 10.10.10.9/29 scope global eth0:0
       valid_lft forever preferred_lft forever
2: eth0    inet6 fe80::a2f6:fdff:fe18:2b13/64 scope link
       valid_lft forever preferred_lft forever

*** Round 1, deleting 3 addresses ***
*** Flush is complete after 1 round ***

e5aba88712 ifupdown: allow duplicate interface definitions
This patch allow to have multiple interface definitions, much like
Debian's ifupdown.  More specifically, it removes the check for a
duplicate definition, so the impact on binary size should be fairly
minimal.

This configuration:

iface eth0 inet static
        address 192.168.0.15
        netmask 255.255.0.0
        gateway 192.168.0.1

iface eth0 inet static
        address 10.0.0.1
        netmask 255.255.255.0

Will add two addresses to eth0 if ip is used.  If ifconfig is used,
the standards methods will likely not stack, but the administrator may
still use the manual method.  The DHCP method may work depending on the
DHCP client in use.

This is a fairly advanced feature for power users who knows what they
are doing.  There are not many other network configuration systems that
allows multiple addresses on an interface.

028524317d ifupdown: pass interface device name for ipv6 route commands
IPv6 routes need the device argument for link-local routes, or they
cannot be used at all. E.g. "gateway fe80::def" seems to be used in
some places, but kernel refuses to insert the route unless device
name is explicitly specified in the route addition.

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.

fe8390e0fe ifupdown: support 'link' address family
Does not configure anything. L2 configuration hook scripts should do
their job on receiving ADDRFAM=link. Configuration will be done only
once, irrespective of L3 protocols used.

Using the 'link' family in the interfaces file conforms to the Debian
implementation:

setting the priority of the static gateway and makes it possible
to specify multiple static gateways.
