Subject: [PATCH RFC ethtool] QSFP Diagnostics Information Support
From: Vidya Sagar Ravipati <vidya@...ulusnetworks.com>
This patch provides support for diagnostics information
for QSFP Plus modules which based on SFF 8436 specification
This implementation is loosely based on current SFP DOM parser
and SFF-8436 specs (ftp://ftp.seagate.com/pub/sff/SFF-8436.PDF)
by SFF Committee.
