H A D | sfp.c | 1cb89a14 Mon Dec 09 08:16:11 CST 2019 Russell King <rmk+kernel@armlinux.org.uk> 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
