Hello folks,
Timestamps should be usually requested explicitly by setting the
SOL_SOCKET/SO_TIMESTAMP option to 1. But if you setup a reception ring
with the SOL_PACKET/PACKET_RX_RING option, timestamps are automatically
enabled at the next packet recepcion.
I think that is a bug so I have written a patch that corrects it.
Thanks.
