Revision b79555d5d8d32643e9d7193341dcaff13bf9ffcd authored by Heiner Kallweit on 12 February 2019, 18:56:15 UTC, committed by David S. Miller on 14 February 2019, 04:44:12 UTC
phylib enables interrupts before phy_start() has been called, and if we receive an interrupt in a non-started state, the interrupt handler returns IRQ_NONE. This causes problems with at least one Marvell chip as reported by Andrew. Fix this by handling interrupts the same as in phy_mac_interrupt(), basically always running the phylib state machine. It knows when it has to do something and when not. This change allows to handle interrupts gracefully even if they occur in a non-started state.
