Subject: [PATCH net-next v2 0/2] mlxsw: Add support for QSFP-DD transceiver type

From: Ido Schimmel <idosch@...lanox.com>

This patch set from Vadim adds support for Quad Small Form Factor
Pluggable Double Density (QSFP-DD) modules in mlxsw.

Patch #1 enables dumping of QSFP-DD module information through ethtool.

Patch #2 enables reading of temperature thresholds from QSFP-DD modules
for hwmon and thermal zone purposes.

Changes since v1 [1]:

Only rebase on top of net-next. After discussing with Andrew and Adrian
we agreed that current approach is OK and that in the future we can
follow Andrew's suggestion to "make a new API where user space can
request any pages it want, and specify the size of the page". This
should allow us "to work around known issues when manufactures get their
EEPROM wrong".

  mlxsw: core: Add ethtool support for QSFP-DD transceivers
  mlxsw: core: Add support for temperature thresholds reading for
    QSFP-DD transceivers
