Subject: [PATCH v3 3/3] stmmac: pci: add MSI support for Intel Quark X1000

From: "Kweh, Hock Leong" <hock.leong.kweh@...el.com>

In Intel Quark SoC X1000, both of the Ethernet controllers support
MSI interrupt handling. This patch enables them to use MSI interrupt
servicing in stmmac_pci for Intel Quark X1000.
