I'm able to successfully communicate with the chip — I can read the version register (0x04) and the PHY configuration register (0xBA). So SPI and reset seem to be working fine. However, the W5500 reports Link: DOWN, ev…

finally i find the culprits damping resistors(33R) in RXN/RXP and TXN/TXP. No need of these resistors. [w5500]
