net: netdevsim: use mock PHC driver

2023-08-09T22:59:21+00:00

I'd like to make netdevsim offload tc-taprio, but currently, this Qdisc
emits a ETHTOOL_GET_TS_INFO call to the driver to make sure that it has
a PTP clock, so that it is reasonably capable of offloading the schedule.

By using the mock PHC driver, that becomes possible.

Hardware timestamping is not necessary, and netdevsim does not support
packet I/O anyway.

netdevsim: don't overwrite read only ethtool parms

2021-12-11T05:23:05+00:00

Ethtool ring feature has _max_pending attributes read-only.
Set only read-write attributes in nsim_set_ringparam.

This patch is useful, if netdevsim device is set-up using NetworkManager,
because NetworkManager sends 0 as MAX values, as it is pointless to
retrieve them in extra call, because they should be read-only. Then,
the device is left in incosistent state (value > MAX).

In order to support more coalesce parameters through netlink,
add two new parameter kernel_coal and extack for .set_coalesce
and .get_coalesce, then some extra info can return to user with
the netlink API.

netdevsim: fix duplicated debugfs directory

2020-09-26T21:19:08+00:00

The "ethtool" debugfs directory holds per-netdev knobs, so move
it from the device instance directory to the port directory.

This fixes the following warning when creating multiple ports:

 debugfs: Directory 'ethtool' with parent 'netdevsim1' already present!
