The process to set up a tap interface is as follows:
- tap interface is created
- An IP address is assigned to the tap interface
- The interface is bring up
- A route is added to the target using the tap
interface
Of all the previous steps, only the first one is
check if it was sucessful. The status of the others
are ignored and all of them are required to have
basic connectivity in the target.
This patch adds the checks for the rest of the stpes
needed to set up the tap interface.

If runqemu is used without actually building any qemu images (i.e. you
downloaded the images) it's likely that qemu-helper-native hasn't been built.
Instead of just saying what command can't be found, tell the user how to solve
their problem.

After switching from ifconfig to ip, networking stopped working. This
commit contains the following fixes:
* set a decent broadcast address for the tap device;
* bring up the device;
* add the route using ip tool instead of the old route tool;

ifconfig and its ilk (net-tools package) is deprecated in favour of iproute2 package
and is now removed by many distro's e.g. Archlinux. So we replace ifconfig with ip utility

This allows core-image-sato to access the WAN.
Thanks to Dexuan Cui for proposing this fix.

By default the runqemu script tries to set the group permissions on any
tap device it creates. The TUNSETGROUP ioctl is not implemented on some
popular host enterprise linux distributions.
Internally the script will exit as follows:
++ /opt/qemux86/bitbake_build/tmp/sysroots/x86_64-linux/usr/bin/tunctl -b -g 100
+ TAP='TUNSETGROUP: Invalid argument'
+ STATUS=1
+ '[' 1 -ne 0 ']'
+ echo 'tunctl failed:'
tunctl failed:
+ echo TUNSETGROUP: Invalid argument
This patch implements a fallback to using the userid as the owner of
the tap device which is supported by all 2.6 kernels, the default remains
to try and use the groupid first.

Fix the IP masquerading settings so that networked QEMU sessions can
reach external networks.
This is a partial fix for [YOCTO #2329].

Without this the command will add a route for the subnet 192.168.7.0 which
means multiple qemu instances can't operate correctly since all but the last
one will be masked out.
