These patches have partial acceptance upstream and are still a WIP, now there is merge window for kernel v6.10 so these will not be reposted until that is over. In the meantime, let's add the current state to OpenWrt so the ethernet on Gemini is up and working (tested on several devices). Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

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.
