Subject: [PATCH 5/5] net: ethernet: cortina: Implement .set_pauseparam()
|
|
|
|
The Cortina Gemini ethernet can very well set up TX or RX
|
|
pausing, so add this functionality to the driver in a
|
|
.set_pauseparam() callback. Essentially just call down to
|
|
phylib and let phylib deal with this, .adjust_link()
|
|
will respect the setting from phylib.
|
