Thanks Andy, for the patch.  I know you're working with Jesse on the performance issue, as our team's igb driver owner, I wanted to say that module parameters, in general, are things we're trying to avoid. They are not permissible in the upstream driver and our out-of-tree driver is provided mainly for people to use in older kernels, not to workaround upstream limitations.  The features are to be equivalent.  We have some module parameters today, due to some business constraints and some grandfathering, but we are trying very hard not to add any more.  You're certainly welcome, of course, to modify your driver in any way that suits your needs.  We'd be willing to consider any solution for this that is acceptable upstream.

Thanks,

Carolyn
