Subject: [PATCH net-next 05/10] net: stmmac: rename multi_msi_en to perch_irq_en
The IP supports per channel interrupt, when intel adds the per channel
interrupt support, the per channel irq is from MSI vector, but this
feature can also be supported on non-MSI platforms. Renaming
multi_msi_en to perch_irq_en to reflects this fact.
