netdevsim: add pause frame stats Add minimal ethtool interface for testing ethtool pause stats. v2: add missing static on nsim_ethtool_ops Signed-off-by: Jakub Kicinski <kuba@kernel.org> Reviewed-by: Saeed Mahameed <saeedm@nvidia.com> Signed-off-by: David S. Miller <davem@davemloft.net>

net: move HDS config from ethtool state Separate the HDS config from the ethtool state struct. The HDS config contains just simple parameters, not state. Having it as a separate struct will make it easier to clone / copy and also long term potentially make it per-queue.

The logic in netdevsim is trying to report the default (ENABLED) if user has not requested any specific setting. The user setting is recorded in dev->cfg, don't depend on kernel_ringparam being pre-populated with it.

netdevsim: don't overwrite read only ethtool parms 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).

net: Add struct kernel_ethtool_ts_info In prevision to add new UAPI for hwtstamp we will be limited to the struct ethtool_ts_info that is currently passed in fixed binary format through the ETHTOOL_GET_TS_INFO ethtool ioctl. It would be good if new kernel code already started operating on an extensible kernel variant of that structure, similar in concept to struct kernel_hwtstamp_config vs struct hwtstamp_config. Since struct ethtool_ts_info is in include/uapi/linux/ethtool.h, here we introduce the kernel-only structure in include/linux/ethtool.h. The manual copy is then made in the function called by ETHTOOL_GET_TS_INFO.
