Subject: [PATCH 0/3] IB 64 bit counter support
Date: Fri, 11 Dec 2015 12:25:32 -0600 [thread overview]
Message-ID: <20151211182532.332343651@linux.com> (raw)
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.
