It is very likely an error that these have usage counts of 0.
(the interfaces are very much up, and a GRE tunnel is configured)
Seeing as the same thing happens with bcm5700 modules from HP it's likely
this is not actually a module problem but a more basic networking
logic fault.
I can't test whether removing tg3/3c59x will result in a panic, but
removing the ip_gre module broke the system (praise ilo...) - Not posting
a trace since it's obvious why it broke...
Comments?
