From 4a8755096466d1002236ac7293eae821b6de87ba Mon Sep 17 00:00:00 2001 From: Sunil Goutham Date: Mon, 15 Jan 2018 18:44:57 +0600 Subject: net: thunderx: add timestamping support This adds timestamping support for both receive and transmit paths. On the receive side no filters are supported i.e either all pkts will get a timestamp appended infront of the packet or none. On the transmit side HW doesn't support timestamp insertion but only generates a separate CQE with transmitted packet's timestamp. Also HW supports only one packet at a time for timestamping on the transmit side. Signed-off-by: Sunil Goutham Signed-off-by: Aleksey Makarov Acked-by: Philippe Ombredanne Signed-off-by: David S.
