Thank you for your time and testing.
Did you notice a increase in throughput?  While testing stock sk(4)
I saw numerous "discard frame w/o leading ethernet header..."
messages under high packet rates. You should not see these messages
anymore in new driver.

Yes. I'd like to know it has locking bugs on dual port handling.
I'd also like to know sk(4) works on second generation chips from
Marvell.(e.g. Yukon-II XL/EC/FE)
