runqemu-ifup: Check if the tap interface is set up correctly
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.
