[OE-core] [meta-oe][PATCH 0/3] runqemu improve networking

[Aws Ismail]

Adrian,

I just have to add one last note here. I had to use
runqemu-gen-tapdevs before runqemu to create the multiple tap devices
(3 in total, tap0 is the default one you've mentioned, and then tap1
and tap2). For example, I did this:

sudo runqemu-gen-tapdevs <my uid> <my guid> 3 <path to my build's
native sysroot>

My thinking was that runqemu would do that for me since I am asking
for two new extra netdev's but apparently not.
