From: Linus Walleij Date: Wed, 29 May 2024 14:00:02 +0000 (+0200) Subject: net: ethernet: cortina: Implement .set_pauseparam() X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=dbdb0918da671bde4e9c4c3e974a5e15358dfa5c;p=users%2Fjedix%2Flinux-maple.git 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.
