These functions contribute to rolling back a partial, failed initialization

of the virtio-net SNP driver instance, or to shutting down a fully
|

|
initialized, running instance.

They are only callable by the VirtioNetInitialize() and the
|

|
|
VirtioNetShutdown() SNP methods. See the state diagram in "VirtioNet.h".
