NAK -- you also need to remove the standard net stats, which are
exported elsewhere
Jeff, can you please explain the reason for this NAK a little more?
Neither Auke nor I understand why you rejected the patch.
This patch just adds the display of a few more stats in Ethtool. It
doesn't affect any other counters, and is really just a convenience
feature. I added this to the driver because of a customer request.
Adding those stats is fine. You guys just need to remove the existing
mess first.
Since we have 1-to-1 mapping of some of our statistics registers to the
net_stats, we could s/net_stats/stats/. However, there are a few
net_stats (e.g. net_stats.rx_errors) that encapsulate more than one e1000
statistic register of which we don't have a private stat member defined.
For those statistics, is it really necessary to add another stat structure
just to rm "net_stats" from that list we pass to ethtool? At best, it
would look something like this...
{ "foo_count", E1000_STAT(stats.foo) }, - { "rx_errors",
E1000_STAT(net_stats.rx_errors) }, + { "rx_errors",
E1000_STAT(eth_stats.rx_errors) }, { "bar_count", E1000_STAT(stats.bar) },
If so, well, OK. I'm just scratching my head as to why it's a "mess"
as-is.
The ethtool get-stats sub ioctl has _always_ been for exporting _only_
NIC-private statistics.
So, no, there is no inherent connection between adding multicast stats and
removing ones that should have never been in the list. But if I don't put
my foot down, this will never get corrected.
okay, here's my offer - we fix it as much as we can. I realize that it may not
be enough but I doubt that removeing stats makes people happy. I suggest that
we take one step in the right direction and another one later if we must.
this is in my queue.

I've missed obvious alternatives before; care to enlighten?
