This:

in the Sniffer class, looks like broken encapsulation (see my review
of test/reorg for details + a proposal about a similar situation).

It's not clear to me why @vmnet and @net are added as an instance
attributes, since they are apparently not used anywhere else in the
class or by its users. Perhaps it's not worth making the class
interface & amount of maintained state larger, if all we need in
practice is a way for some methods to get the MAC address and
bridge name?

Now that this isn't a step definition anymore, but an instance method,
I don't think `puts' is the optimal way to report detailed information
before throwing an exception. How about storing the detailed text in
a local variable, in each of the `if' blocks, and then passing this
additional information to `raise'?

It seems to me 48a32dd introduces a dependency on @custom_sniffer,
while this attribute is only created by the next commit.
This breaks bisection.

That's all for today :)

Once that other one has its own ticket, #5644 can be marked as blocked
by it.

Cheers!
