igb: Enable reading of wake up packet
Currently, in igb_resume(), igb driver ignores the Wake Up Status (WUS) and Wake Up Packet Memory (WUPM) registers. This patch enables the igb driver to read the WUPM if the controller was woken by a wake up packet that is not more than 128 bytes long (maximum WUPM size), then pass it up the kernel network stack.
