| Subject: sh_eth: r8a7790: Handle the RFE (Receive FIFO overflow Error) |
| interrupt |
| |
| The RFE interrupt is enabled for the r8a7790 but isn't handled, |
| resulting in the interrupts core noticing unhandled interrupts, and |
| eventually disabling the ethernet IRQ. |
| |
| Fix it by adding RFE to the bitmask of error interrupts to be handled |
| for r8a7790. |
