Introduce the userspace entry point for PHY MSE diagnostics via
ethtool netlink. This exposes the core API added previously and
returns both capability information and one or more snapshots.
Userspace sends ETHTOOL_MSG_MSE_GET. The reply carries:
- ETHTOOL_A_MSE_CAPABILITIES: scale limits and timing information
- ETHTOOL_A_MSE_CHANNEL_* nests: one or more snapshots (per-channel
if available, otherwise WORST, otherwise LINK)
Link down returns -ENETDOWN.
Changes:
- YAML: add attribute sets (mse, mse-capabilities, mse-snapshot)
and the mse-get operation
- UAPI (generated): add ETHTOOL_A_MSE_* enums and message IDs,
ETHTOOL_MSG_MSE_GET/REPLY
- ethtool core: add net/ethtool/mse.c implementing the request,
register genl op, and hook into ethnl dispatch
- docs: document MSE_GET in ethtool-netlink.rst
The include/uapi/linux/ethtool_netlink_generated.h is generated
from Documentation/netlink/specs/ethtool.yaml.
