net/igb: Fix kexec with igb (rev. 3)
Impact: Fix
Yinghai Lu found one system with 82575EB where, in the kernel that is
kexeced, probe igb failed with -2, the reason being that the adapter
could not be brought back from D3 by the kexec kernel, most probably
due to quirky hardware (it looks like the same behavior happened on
forcedeth).
Prevent igb from putting the adapter into D3 during shutdown except
when we going to power off the system. For this purpose, seperate
igb_shutdown() from igb_suspend() and use the appropriate PCI PM
callbacks in both of them.
