[Beowulf] Any pointers to the what the fields in the sysfs for infiniband are?

[Joe Landman]

I am working on extracting meaningful data on various components for our 
monitoring tools, and realized that I don't have a good writeup anywhere 
(other than the source) of what the fields are.  Anyone have or know of 
such a writeup?

For example:

root at n01:/sys/devices/pci0000:00/0000:00:03.0/0000:02:00.0/infiniband/mlx5_0/ports/1/counters_ext# 
pwd/sys/devices/pci0000:00/0000:00:03.0/0000:02:00.0/infiniband/mlx5_0/ports/1/counters_ext
root at n01:/sys/devices/pci0000:00/0000:00:03.0/0000:02:00.0/infiniband/mlx5_0/ports/1/counters_ext# 
ls -alF
total 0
drwxr-xr-x 2 root root    0 Jun 12 21:19 ./
drwxr-xr-x 7 root root    0 Jun 12 21:19 ../
-r--r--r-- 1 root root 4096 Jun 12 21:19 port_multicast_rcv_packets
-r--r--r-- 1 root root 4096 Jun 12 21:19 port_multicast_xmit_packets
-r--r--r-- 1 root root 4096 Jun 12 21:19 port_rcv_data_64
-r--r--r-- 1 root root 4096 Jun 12 21:19 port_rcv_packets_64
-r--r--r-- 1 root root 4096 Jun 12 21:19 port_unicast_rcv_packets
-r--r--r-- 1 root root 4096 Jun 12 21:19 port_unicast_xmit_packets
-r--r--r-- 1 root root 4096 Jun 12 21:19 port_xmit_data_64
-r--r--r-- 1 root root 4096 Jun 12 21:19 port_xmit_packets_64

I can infer a number of things from the names, but I'd like to be sure 
of what I am looking at.  I'll look at the source if I can't find a 
summary ... hence my question.

Thanks in advance!
