2024-04-08netdevsim: report stats by default, like a real deviceJakub Kicinski1-0/+11
Real devices should implement qstats. Devices which support pause or FEC configuration should also report the relevant stats. nsim was missing FEC stats completely, some of the qstats and pause stats required toggling a debugfs knob. Note that the tests which used pause always initialize the setting so they shouldn't be affected by the different starting value.

2023-08-09net: netdevsim: use mock PHC driverVladimir Oltean1-0/+11
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.

2021-12-10netdevsim: don't overwrite read only ethtool parmsFilip Pokryvka1-1/+4
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.

2020-09-26netdevsim: fix duplicated debugfs directoryJakub Kicinski1-1/+1
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!
