+Subject: [PATCH] smsc95xx: configure LED outputs
+
+SMSC LAN9500 has dual purpose GPIO/LED pins, and by default at power-on
+these are configured as GPIOs. This means that if LEDs are fitted they
+won't ever light.
+
+This patch sets them to be LED outputs for speed, duplex and
+link/activity.

+Subject: [PATCH] smsc95xx: remove EEPROM loaded check
+
+The eeprom read & write commands currently check the E2P_CMD_LOADED_ bit is
+set before allowing any operations. This prevents any reading or writing
+unless a correctly programmed EEPROM is installed.
+
+This patch removes the check, so it is possible to program blank EEPROMS
+via ethtool.
