At least, being able to disable the feature at module load time
would be acceptable. Many people who often need to sniff on decent
machines would always keep it disabled.
I'm willing to accept the feature, in whatever form, as long
as the performance issue is dealt with properly.

I agree with disabling the hw acceleration feature by manually would
be a non-negative solution.
IMO implementation in the ethtool seems better than module param.
As like Auke mentioned.
If you guys confirm it, I'll try it.

I still think promiscous mode should disable all filters (which would
also provide a consistent view between accerlated and non-accerlated
devices), but an ethtool option is better than nothing :)
