From 68d5cd09e8919679ce13b85950debea4b2e98e04 Mon Sep 17 00:00:00 2001 From: Daniel Golle Date: Thu, 10 Oct 2024 14:07:26 +0100 Subject: [PATCH 4/5] net: phy: realtek: change order of calls in C22 read_status() Always call rtlgen_read_status() first, so genphy_read_status() which is called by it clears bits in case auto-negotiation has not completed. Also clear 10GBT link-partner advertisement bits in case auto-negotiation is disabled or has not completed.
