The ethernet packet timestamping is not something that can be handled by the driver. I mean that of course we can extend the driver to add timestamps, but those will be SW timestamps and will not actually represent time when packets arrive/leave HW. I mean that with having all the DMA stuff in ethernet for reception the actual RX processing may be deferred, so the packet that enters HW at X, but processed at X+N staying for N in memory after DMA operation is finished, but SW didn't start processing, so N will be a small random value. -- This is an automated message from the Apache Git Service.
