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!
