I am happy that you should say that.
I will try to create a patch for e100, e1000e, igb and ixgbe.
Before that, I should fix the following problems.

Thank you for your tests.
Oh, My patch is full of problem.
The rest is my work.

I will resend the patch after test of all ethtool's options.
At that time, I will tell you contents of my tests.

And I sad WOL works on my patch in previous mail.
But WOL doesn't work. Sorry, I wasn't myself.
I will fix it too.
