ethtool for Debian
------------------
Most settings that can be controlled through ethtool can be specified
in /etc/network/interfaces. They will then be applied to interfaces
that are brought up automatically at boot time or using the 'ifup'
command. The following settings are supported:
Link mode (--change):
link-speed <speed>
link-duplex half|full
Ethernet settings (--change):
ethernet-autoneg on|off|<mask>
ethernet-port <port>
ethernet-wol <mode> [<pass-key>]
Driver control (--change):
driver-message-level <level>
Ethernet flow control (--pause):
ethernet-pause-rx on|off
ethernet-pause-tx on|off
ethernet-pause-autoneg on|off
Protocol offload (--offload):
offload-rx on|off
offload-tx on|off
offload-sg on|off
offload-tso on|off
offload-ufo on|off
offload-gso on|off
offload-lro on|off
(etc.)
Hardware tuning (--coalesce, --ring):
hardware-irq-coalesce-adaptive-rx on|off
hardware-irq-coalesce-adaptive-tx on|off
hardware-irq-coalesce-rx-usecs <n>
hardware-irq-coalesce-rx-frames <n>
(etc.)
hardware-dma-ring-rx <size>
hardware-dma-ring-rx-mini <size>
hardware-dma-ring-rx-jumbo <size>
hardware-dma-ring-tx <size>
Example:
iface eth0 inet dhcp
link-speed 100
link-duplex full
ethernet-autoneg off
ethernet-wol s 46:65:62:69:61:6e
