BCM54616S feature "PHY_GBIT_FEATURES" was removed by commit dcdecdcfe1fc
("net: phy: switch drivers to use dynamic feature detection"). As dynamic
feature detection doesn't work when BCM54616S is working in RGMII-Fiber
mode (different sets of MII Control/Status registers being used), let's
set "PHY_GBIT_FEATURES" for BCM54616S explicitly.

Hi Tao

What exactly does it get wrong?

     Thanks

Hi Andrew,

BCM54616S is set to RGMII-Fiber (1000Base-X) mode on my platform, and none of the features (1000BaseT/100BaseT/10BaseT) can be detected by genphy_read_abilities(), because the PHY only reports 1000BaseX_Full|Half ability in this mode.

Are you going to use the PHY in copper or fibre mode?
In case you use fibre mode, why do you need the copper modes set as supported?
Or does the PHY just start in fibre mode and you want to switch it to copper mode?

Thanks,

Tao
