+On the receive side, if the device handled decryption and authentication
 successfully, the driver will set the decrypted bit in the associated

 are handled normally. ``ktls`` is informed when data is queued to the socket

 Assuming segments are received in order, the device should be able to perform
 crypto operations and authentication regardless of segmentation. For this
