Hi! Sorry about the delay from v2.
This set adds support for pause frame statistics. First pause frame info is extended to support --json. Pause stats are first of this kind of statistics so add support for a new flag (--include-statistics). Next add support for dumping policy to check if the statistics flag is supported for a given subcommand. Last but not least - display statistics. v3: - rename the ctx variable to policy_ctx - instead of returning the flags policy save it to a member of struct nl_context, for potential reuse. Also we don't have to worry about returning flags and negative errors from the read helper this way :) Jakub Kicinski (7): update UAPI header copies pause: add --json support separate FLAGS out in -h add support for stats in subcommands netlink: prepare for more per-op info netlink: use policy dumping to check if stats flag is supported pause: add support for dumping statistics ethtool.8.in | 7 ++ ethtool.c | 17 +++- internal.h | 1 + netlink/coalesce.c | 6 +- netlink/msgbuff.h | 6 ++ netlink/netlink.c | 179 ++++++++++++++++++++++++++++++++++++++--- netlink/netlink.h | 31 +++++-- netlink/pause.c | 111 ++++++++++++++++++++++--- uapi/linux/genetlink.h | 11 +++ uapi/linux/netlink.h | 4 + 10 files changed, 336 insertions(+), 37 deletions(-) -- 2.26.2
