Merge branch 'review/pause-stats-v3' into master
Jakub Kicinski:
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 :)
