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 4/5] net: ethernet: cortina: Use negotiated TX/RX pause
|
|
|
|
Instead of directly poking into registers of the PHY, use
|
|
the existing function to query phylib about this directly.
