Subject: [ethtool PATCH v2 2/4] ethtool:Reorganizing SFF-8024 fields for SFP/QSFP
From: Vidya Sagar Ravipati <vidya@...ulusnetworks.com>
This patch provides following support
a) Reorganized fields based out of SFF-8024 fields i.e. Identifier/
Encoding/Connector types which are common across SFP/SFP+ (SFF-8472)
and QSFP+/QSFP28 (SFF-8436/SFF-8636) modules into sff-common files.
Standards for SFF-8024
a) SFF-8024 Rev 4.0 dated May 31, 2016
Signed-off-by: Vidya Sagar Ravipati <vidya@...ulusnetworks.com>
Acked-by: Bert Kenward <bkenward@...arflare.com>
