Subject: [PATCH ethtool-next v2 0/3] Add ability to flash modules' firmware

CMIS compliant modules such as QSFP-DD might be running a firmware that
can be updated in a vendor-neutral way by exchanging messages between
the host and the module as described in section 7.2.2 of revision
4.0 of the CMIS standard.

Add ability to flash transceiver modules' firmware over netlink.

Example output:

 # ethtool --flash-module-firmware eth0 file test.img

Transceiver module firmware flashing started for device swp23
Transceiver module firmware flashing in progress for device swp23
Progress: 99%
Transceiver module firmware flashing completed for device swp23

In addition, add some firmware and CDB messaging information to
ethtool's output for observability.

Patchset overview:
Patches #1-#2: adds firmware info to ethtool's output.
Patch #3: adds ability to flash modules' firmware.

v2:
	* Remove patch #3 of updating header, since it was already done.
	* s/ETHTOOL_A_MODULE_FW_FLASH_PASS/ETHTOOL_A_MODULE_FW_FLASH_PASSWORD
