From dba1e4660a87927bdc03c23e36fd2c81a16a7ab1 Mon Sep 17 00:00:00 2001 From: Xiaoliang Yang Date: Thu, 24 Sep 2020 09:57:46 +0800 Subject: [PATCH] net: dsa: felix: convert TAS link speed based on phylink speed state->speed holds a value of 10, 100, 1000 or 2500, but QSYS_TAG_CONFIG_LINK_SPEED expects a value of 0, 1, 2, 3. So convert the speed to a proper value.
