[PATCH net-next v16 14/14] netlink: specs: Enhance tsinfo netlink attributes and add a tsconfig set command

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Add new attributed to tsinfo allowing to get the tsinfo from a phc provider
(composed by a phc index and a phc qualifier) on a netdevice's link.
Add simultaneously a tsconfig command to be able to get and set hwtstamp
configuration for a specified phc provider.

Here is few examples:
./ynl/cli.py --spec netlink/specs/ethtool.yaml --no-schema
             --dump tsinfo-get
             --json '{"header":{"dev-name":"eth0"}}'
