^This is against the coding style, keep it 1 variable definition per line.

We could also save 1 comparison with
'if (net->bandwidth) {
    if (in){}
    if (out){}
}'

...alternatively, you could introduce a structure with all the attributes
packed and introduce a helper like testDomainFillInterfaceParameters and then
you'd do

if (net->bandwidth)
    testDomainFillInterfaceParameters(net->bandwidth, &params);

Otherwise looking good.
