Ok, I found more sources of mis-isolation in tests, which could also be a real
bug (ie, not only affect tests).

1. SeedManager::SetSeed(..) does not do anything if the RNG has been
initialized already. This means, in some situations SetSeed could be ignored,
which I guess is not good for experiments either.

2. Mac48Address has global state that cannot be controlled (ie: a static
variable controlling the MAC sequence), so MACs assigned in PCAP-checking tests
make tests fail when ran in succession. If I change the static by a
GlobalValue, it gets fixed (thanks to the patch that resets GlobalValue s).
Thing is, PCAPs need re-generation (MACs are still different than expected in
current PCAPs, but consistent and reproducible).

Anybody knows how to generate new PCAPs?
