Subject: [PATCH ethtool v2] Add QSFP-DD support
The Common Management Interface Specification (CMIS) for QSFP-DD shares
some similarities with other form factors such as QSFP or SFP, but due to
the fact that the module memory map is different, the current ethtool
version is not able to provide relevant information about an interface.
This patch adds QSFP-DD support to ethtool. The changes are similar to
the ones already existing in qsfp.c, but customized to use the memory
addresses and logic as defined in the specifications document.
Page 0x00 (lower and higher memory) are always implemented, so the ethtool
expects at least 256 bytes if the identifier matches the one for QSFP-DD.
For optical connected cables, additional pages are usually available.
Several functions from qsfp.c could be reused, so an additional parameter
was added to each and the functions were moved to sff-common.c.
Changelog (diff from v1):
* Report cable length in meters instead of kilometers
* Fix bad value for QSFP_DD_DATE_VENDOR_LOT_OFFSET
* Fix initialization for struct qsfp_dd_diags
* Remove unrelated whitespace cleanups in qsfp.c and Makefile.am
