[E1000-devel] IOAT and ixgbe current status

2016-09-22 Thread Michał Purzyński
What's the current status ofI/O and ixgbe driver and 82599 cards? Is it even used? How's the performance? If it is used, do you know in which stage exactly? Is it used to copy data from driver buffers (those that card does DMA into from FIFO) to sk_buff or from sk_buff to socket buffers?
