Subject: [PATCH v2 net-next 0/6] net: dsa: mv88e6xxx: Add "eth-mac" and "rmon" counter group support
The majority of the changes (2/6) are about refactoring the existing
ethtool statistics support to make it possible to read individual
counters, rather than the whole set.
4/6 tries to collect all information about a stat in a single place
using a mapper macro, which is then used to generate the original list
of stats, along with a matching enum. checkpatch is less than amused
with this construct, but prior art exists (__BPF_FUNC_MAPPER in
include/uapi/linux/bpf.h, for example).
With that in place, adding the actual counter groups is pretty
straight forward (5-6/6).
v1 -> v2:
- Added 1/6
- Added 3/6
- Changed prototype of stats operation to reflect the fact that the
number of read stats are returned, no errors
- Moved comma into MV88E6XXX_HW_STAT_MAPPER definition
- Avoid the construction of mapping table iteration which relied on
struct layouts outside of mv88e6xxx's control
