Cover letter [PATCH 0/3] IB 64 bit counter support V2
V1->V2 Add detection of the capability for 64 bit counter support and lots
of improvements as a result of suggestions by Hal Rosenstock.
Currently we only use 32 bits for the packet and byte counters. There have been extended countes available for some time but we have no support for those yet upstream. We keep having issues with 32 bit counters wrapping. Especially the byte counter can wrap frequently (as in multiple times per minute)
This patch adds 4 new counters and updates 4 32 bit counters to use the 64 bit sizes so that they no longer wrap.
Should the device not support 64 bit counters then only the original 32 bit counters will be visible.
