First problem: the EEPROM is set to forced full duplex.
This is almost certainly wrong for your hub.
The speed problem is likely because you have a dual speed repeater. The
595 speed autosensing must be done by the driver. In order to not screw
up 10baseT repeaters with 100baseTx link beat the driver first sets the
speed to 10baseT and checks for link beat. If it finds 10baseT link
beat it never tries 100baseTx.
The solution is to set the speed to 100baseTx using a driver option.
The 3c595 is a very old card.
You will get better performance from any modern card.
