From: Lukasz Cieplicki <lukaszx.cieplicki@intel.com> stable inclusion from stable-5.10.56 commit 75ebe1d355b5b179568009ef35042d3c7be7ee00 bugzilla: 176004 https://gitee.com/openeuler/kernel/issues/I4DYZ4 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- commit dc614c46178b0b89bde86ac54fc687a28580d2b7 upstream. In case of PHY type error occurs, the message was too generic. Add additional info to PHY type error indicating that it can be wrong cable connected.
