+Subject: [PATCH 4/4] net: sfp: re-attempt probing for phy
+
+Some 1000BASE-T PHY modules take a while for the PHY to wake up.
+Retry the probe a number of times before deciding that the module has
+no PHY.
+
+Tested with:
+ Sourcephotonics SPGBTXCNFC - PHY takes less than 50ms to respond.
+ Champion One 1000SFPT - PHY takes about 200ms to respond.
+ Mikrotik S-RJ01 - no PHY
+
