[systemd-devel] RFC: support ethtool pause setting in systemd.link

[Stephen Hemminger]

Ethernet flow control (pause) is a setting which often is best disabled.
Systemd has nice way to configure other link settings like WoL, TSO, etc
but doesn't have a way to configure pause.

It would be good to have something like:

[Match]
Driver=ixgbe

[Link]
Pause=off


Possible values should subset of ethtool.
"off" = autoneg off, rx off, tx off
"autoneg" = autoneg on
"tx" = autoneg off, rx off, tx on
"rx" = autoneg off, rx on, tx off
