From aa230e7dc2ab01db5b630f427e57297ffc25c884 Mon Sep 17 00:00:00 2001 From: Atish Patra Date: Fri, 7 Sep 2018 10:22:27 -0700 Subject: [PATCH 09/11] RISC-V: Networking fix Hack It looks like that kernel driver now supports reseting the signal one additional time. As it had been already reset twice in FSBL, PHY gets into incorrect state causing below error. ---------------------------------------------------------------------- macb 10090000.ethernet (unnamed net_device) (uninitialized): Could not attach to PHY macb: probe of 10090000.ethernet failed with error -110 ---------------------------------------------------------------------- This patch is just a temporary fix until we have a fix a FSBL. It is just a **HACK** and **NOT TO BE MERGED** into mainline.
