Subject: [RESEND v1 net-next 3/5] net: stmmac: introduce MSI Interrupt routines for mac, safety, RX & TX
From: Ong Boon Leong <boon.leong.ong@...el.com>
Now we introduce MSI interrupt service routines and hook these routines
up if stmmac_open() sees valid irq line being requested:-
stmmac_mac_interrupt() :- MAC (dev->irq), WOL (wol_irq), LPI (lpi_irq)
stmmac_safety_interrupt() :- Safety Feat Correctible Error (sfty_ce_irq)
& Uncorrectible Error (sfty_ue_irq)
stmmac_msi_intr_rx() :- For all RX MSI irq (rx_irq)
stmmac_msi_intr_tx() :- For all TX MSI irq (tx_irq)
Each of IRQs will have its unique name so that we can differentiate
them easily under /proc/interrupts.
