What's the point of catching this exception?
The error for ENOPNOTSUPP will be both very rare (not sure I understand
where you expect it to come from TBH), and also about as meaningful as 
the skip. Just let the exception propagate, it's fine.

Otherwise Pylint complains:
W0707: Consider explicitly re-raising using 'raise KsftSkipEx('kernel does not support AF_PACKET multicast dump') from e' (raise-missing-from)
