> Improve myri10ge parity error detection and recovery:
> 1) Don't restore PCI config space to a rebooted NIC until AFTER the
>    host is quiescent.
> 2) Let myri10ge_close() know the NIC is dead, so it won't waste time
>    waiting for a dead nic to respond to MXGEFW_CMD_ETHERNET_DOWN
> 3) When the NIC is quiet (link down, or otherwise idle link) use
>    a pci config space read to detect a rebooted NIC.  Otherwise
>    we might never notice that a NIC rebooted
