This is wrong. IRQ for 5gbase-r and 10gbase-r is enabled differently.
Please look at how I did it in my proposal
https://www.mail-archive.com/netdev@vger.kernel.org/msg347854.html
Please look at the following functions in that patch:
mv88e6393x_serdes_irq_enable_10g()
mv88e6393x_serdes_irq_enable()
mv88e6393x_serdes_irq_status_10g()
irqreturn_t mv88e6393x_serdes_irq_status()
and also at the constants added to serdes.h in that patch
#define MV88E6393X_10G_INT_ENABLE 0x9000
#define MV88E6393X_10G_INT_LINK_CHANGE BIT(2)
#define MV88E6393X_10G_INT_STATUS 0x9001
