+Subject: [PATCH] net: phy: broadcom: Add support code for reading PHY counters
+
+Broadcom PHYs expose a number of PHY error counters: receive errors,
+false carrier sense, SerDes BER count, local and remote receive errors.
+Add support code to allow retrieving these error counters. Since the
+Broadcom PHY library code is used by several drivers, make it possible
+for them to specify the storage for the software copy of the statistics.
