I doubt it really needs rebooting.  More likely running
    ifdown eth0 && ifup eth0
would restore it.

How is the network set up?  What sort of hardware?  What sort of
addressing scheme?  When you power up the switch, does the "link"
light come on (both on the switch and the NIC)?

I have a sort of similar situation with a laptop.  It has a PCMCIA NIC
and obtains its address via DHCP.  If I close the laptop's cover the
machine will suspend.  After reopening the cover I need to run the
above command to reset the interface or else I won't have networking.
In my case I'm certain the problem is related to the hardware/software
not returning from suspend as would be expected.
