While the hardware supports 2 Tx and 2 Rx queues we do not have the full implementation in our Linux e1000e driver to support this. The performance to be gained from multiple queues is very small, and was not a requirement for our Linux software. So its not supported right now, and I doubt it will be implemented for e1000e as there is likely to be very little benefit. Although we may reconsider based on customer feedback. -- Cheers, Jeff ------------------------------------------------------------------------------ _______________________________________________ E1000-devel mailing list E1000-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/e1000-devel
