At the same time the 'macirq' (eth0) IRQ would stop being triggered at all and as consequence the GMAC IRQs never ACKed. After a painful investigation the problem seemed to be due to a wrong defined IRQ type for the GMAC IRQ that should be LEVEL_HIGH instead of EDGE_RISING. The change in the macirq IRQ type also solved another long standing issue affecting this SoC/PHY where EEE was causing the network connection to die after stressing it with iperf3 (even though much sooner). It's now possible to remove the 'eee-broken-1000t' quirk as well.
