[ofa-general] [PATCH RFC] RDMA/cxgb3: Add protocol statistics to iw_cxgb3.

[Roland Dreier]

> I take this back.  These stats are a subset of the IP and TCP MIBs.

> How does that sound?

Sounds great except I'm not thrilled about the exact sysfs pathname...
I guess iWARP devices always have one port (??)  (physically multiport
NICs show up as multiple devices?  don't have good access to my system
with a two-port rnic to check)  The only point of all that being that
$device/ports/$port may not make total sense.

But still why not follow the convention we already have and just use

$device/ports/1/counters/

and use the tcp and ip mib names rather than ib pma names.
