Subject: [PATCH 82/82] net: sparx5/lan969x: Add support for ethtool pause
|
|
parameters
|
|
|
|
Implement get_pauseparam() and set_pauseparam() ethtool operations for
|
|
Sparx5 ports. This allows users to query and configure IEEE 802.3x
|
|
pause frame settings via:
|
|
|
|
ethtool -a ethX
|
|
ethtool -A ethX rx on|off tx on|off autoneg on|off
|
|
|
|
The driver delegates pause parameter handling to phylink through
|
|
phylink_ethtool_get_pauseparam() and phylink_ethtool_set_pauseparam().
|
|
|
|
The underlying configuration of pause frame generation and reception is
|
|
already implemented in the driver; this patch only wires it up to the
|
|
standard ethtool interface, making the feature accessible to userspace.
