-stable review patch. If anyone has any objections, please let us know. ------------------ From: Auke Kok e1000: Fix suspend/resume powerup and irq allocation From: Auke Kok After 7.0.33/2.6.16, e1000 suspend/resume left the user with an enabled device showing garbled statistics and undetermined irq allocation state, where `ifconfig eth0 down` would display `trying to free already freed irq`. Explicitly free and allocate irq as well as powerup the PHY during resume fixes when needed.
