Subject: [PATCH net-next v2 6/6] net: hns3: add hwtstamp_get/hwtstamp_set ops
And .ndo_hwtstamp_get()/.ndo_hwtstamp_set() callbacks to HNS3 framework
to support HW timestamp configuration via netlink and adopt hns3pf to
use .ndo_hwtstamp_get()/.ndo_hwtstamp_set() callbacks.
Reviewed-by: Jacob Keller <jacob.e.keller@...el.com>
Signed-off-by: Vadim Fedorenko <vadim.fedorenko@...ux.dev>
---
v1 -> v2:
- actually assign ndo_tstamp callbacks
