I've got a bug report for someone using a Intel OPA devices in a bond,
and it appears these devices have a hardware address length of 20,
opposed to the typical 6 on ethernet. When they dump
/proc/net/bonding/bondX, it only prints the first 6 of the address, per
%pM and mac_address_string(), while sysfs for the interface does print
the right thing, since it uses sysfs_print_mac(), which takes a length
argument.
So the question is... What's the best route to take here? Expand %pM to
support variable length hardware addresses? Use sysfs_* in procfs?
Reinvent the wheel? Nothing I've tinkered with just yet feels very
clean, on top of not actually working yet. :)
