4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Eugenia Emantayev <euge...@mellanox.com>


[ Upstream commit d439c84509a510e864fdc6166c760482cd03fc57 ]

The overflow_period is calculated in seconds. In order to use it
for delayed work scheduling translation to jiffies is needed.

Fixes: ef9814deafd0 ('net/mlx5e: Add HW timestamping (TS) support')
