Re: [E1000-devel] ixgbe : RSS does not work for VLAN packets

[Ko, S. S <ste...@in...>]

Hey Benzi,

As I have mentioned, without significant effort on the driver's part, I'm afraid this isn't yet possible, therefore, simply flipping a bit in the register is unlikely to work.

I have copied the mailing list in case others want chime in.

Regards,

Stephen

i just wonder that if its already implemented in the HW there is some register to enable it via the driver. maybe its not tested etc but at least we can try you know.
