ethtool: Add ability to control transceiver modules' power mode
Add ability to control transceiver modules' power mode over netlink.
Example output and usage:
# ip link set dev swp11 up
$ ethtool --show-module swp11
Module parameters for swp11:
power-mode-policy: high
power-mode: high
$ ethtool --json --show-module swp11
[ {
"ifname": "swp11",
"power-mode-policy": "high",
"power-mode": "high"
} ]
# ethtool --set-module swp11 power-mode-policy auto
$ ethtool --show-module swp11
Module parameters for swp11:
power-mode-policy: auto
power-mode: high
# ethtool --set-module swp11 power-mode-policy auto
# ethtool --set-module swp11 power-mode-policy high
Despite three set commands, only two notifications were emitted, as the
kernel only emits notifications when an attribute changes:
$ ethtool --monitor
listening...
Module parameters for swp11:
power-mode-policy: auto
power-mode: high
