[PATCH ethtool-next 0/5] stats: add support for per-channel and XDP standard stats

[Alexander Lobakin]

This series adds bits to support per-channel standard statistics,
mentions the new "xdp" group of standard stats landed in Linux with
commit 44eee6116fda ("ethtool, stats: introduce standard XDP statistics")
and fixes one typo in the man page while at it.

The original series for the kernel part is here: [0]

[PATCH ethtool-next 2/5] stats: factor out one stat field printing

[Alexander Lobakin]

Move the code that takes one stat field nlattr, validates and prints
it in either stdout or JSON, into a separate function.
It will later be reused by per-channel statistics printing.

[PATCH ethtool-next 3/5] stats: add support for per-channel statistics [blocks]

[Alexander Lobakin]

Treat ETHTOOL_A_STATS_GRP_STAT_BLOCK as a block of the standard
stats for one channel and print them prefixed with "channel%u-".
The index will be started from 0 and incremented automatically
for each new attr of that type.
This means that stats blocks should follow each other one by one
according to their channel number, otherwise the output can mess
up with the indices.
