c4fdf75d3d ip link: fix display of interface groups
This change adds the interface group to the output of "ip link show".

It also makes "ip link" print _all_ devices if no group filter is specified;
previously, only interfaces of the default group (0) were shown.

9eff0e5cc4 bridge: Add vlan configuration support
Recent kernel patches added support for VLAN filtering on the bridge.
This functionality allows one to turn a basic bridge into a VLAN bridge,
where VLANs dicatate packet forwarding and header transformation.

To configure the VLANs on the bridge and its ports a new command is
added to the 'bridge' utility.

   # bridge vlan add dev eth0 vid 10 pvid untagged brdev
   # bridge vlan add
   # bridge vlan delete dev eth0 vid 10
   # bridge vlan show

This command supports the following flags:
   master - peform the operation on the software bridge device.  This is
	    the default behavior.
   self  -  perform the operation on the hardware associated with the port.
            This flag is required when the device is the bridge device and
	    the configuration is desired on the bridge device itself (not
	    one of the ports).
   pvid  -  Set the PVID (port vlan id) for a given port.  Any untagged
            frames arriving on the port will be assigned to this vlan.
   untagged - Sets the egress policy of for a given vlan.  Default port
            egress policy is tagged.  Set this flag if you wish traffic
            associated with this VLAN to exit the port untagged.

Platforms have different alignment requirements which need to be
fulfilled by the compiler. If the structure elements are already
4 byte (NLMGS_ALIGNTO) aligned by the compiler adding an explicit
padding element (align_rta) is not allowed.
Use __attribute__ ((aligned (NLMSG_ALIGNTO))) in order to achieve
the required alignment.

2c389b0f31 iproute2: drop libresolv
Hello!

While building the iproute package in Debian I get warnings from
package helpers like this:

dpkg-shlibdeps: warning: package could avoid a useless dependency if debian/iproute/sbin/tc debian/iproute/usr/bin/lnstat debian/iproute/bin/ip debian/iproute/bin/ss debian/iproute/sbin/bridge debian/iproute/sbin/rtmon were not linked against libresolv.so.2 (they use none of the library's symbols)

The -lresolv in ./Makefile seems to come from pre-historic times (before
iproute2 git history, possibly from libc5/pre-glibc days).
I couldn't find out if/why there was any reason for linking to libresolv.
Does anyone know if there are any valid reasons for keeping it still?

If not, I'd be happy to see it go.... while at it I also removed includes
of <resolv.h> which I also couldn't find any reason for, but this is
just an added bonus of the patch (and there are probably more unneeded
includes that could be dropped in the same sources).

9b2cdc00da iproute: fix unit conversion of rtt/rttvar/rto_min
Since July 2008 (2.6.27, c1e20f7c8b9), the kernel stores the values for
RTAX_{RTT{,VAR},RTO_MIN} in milliseconds. When using a kernel > 2.6.27 with
the current iproute2, conversion of these values is broken in either way.

This patch
 * updates the code to pass and retrieve milliseconds;
 * since values < 1msec would be rounded up, also drops the usec/nsec variants;
 * since there is no way to query kernel HZ, also drops the jiffies variant.

Arguments such as
	rtt		3.23sec
	rto_min		0xff
	rto_min		0.200s
	rttvar		25ms
now all work as expected when reading back previously set values.

3bc1c4f297 iproute2: Fix filtering related to flushing IP addresses.
The old 'ip addr flush' logic had several flaws:

* It reversed logic for primary v/s secondary flags
  (though, it sort of worked right anyway)

* The code tried to remove secondaries and then primaries,
  but in practice, it always removed one primary per loop,
  which not at all efficient.

* The filter logic in the core would run only the first
  filter in most cases.

* If you used '-s -s', the ifa_flags member would be
  modified, which could make future filters fail
  to function fine.

This patch attempts to fix all of these issues.

b49240ec7e flush secondary addresses before primary ones
Unless promote_secondaries has been active deleting the primary address of
an interface will automatically delete all the secondary addresses.

In the case where ip flush requests the primary then secondary addresses to
be removed - which is the order the addresses are returned by the kernel -
this will cause an error as by the time the request to remove a secondary
address is made it will be missing as it will have been deleted in the
course of deleting the primary address.

This approach to solving this problem orders requests for the
deletion of secondary addresses before primary ones providing
rtnl_dump_filter_l(), a version of rtnl_dump_filter() that
iterates over a list of filters. And by providing two specialised
filters print_addrinfo_secondary() and print_addrinfo_primary().

rtnl_dump_filter_l() first iterates over all addresses using
print_addrinfo_secondary(), which appends secondary addresses to the
request buffer.  Then again using print_addrinfo_primary() which appends
primary addresses.

This approach should work regardless of it promote_secondaries is
active or not. And regardless of if any primary of secondary addresses
are present or not.
