[PATCH 1/2] OvmfPkg/VirtioNetDxe: document Rx/Tx allocs and mappings on Init/Shutdown

[Laszlo Ersek]

Document the following actions on the

  EfiSimpleNetworkStarted <-> EfiSimpleNetworkInitialized

state transitions:

* from commit 46b11f00ac70 ("OvmfPkg/VirtioNetDxe: alloc RxBuf using
  AllocateSharedPages()", 2017-09-14):

  VirtioNetInitRx ->
  { VirtIo->AllocateSharedPages, VirtioMapAllBytesInSharedBuffer }

  VirtioNetShutdownRx ->
  { VirtIo->UnmapSharedBuffer, VirtIo->FreeSharedPages }

* from commit 891f016c1b99 ("OvmfPkg/VirtioNetDxe: dynamically alloc
  transmit header", 2017-09-14):

  VirtioNetInitTx ->
  { VirtIo->AllocateSharedPages, VirtioMapAllBytesInSharedBuffer }

  VirtioNetShutdownTx ->
  { VirtIo->UnmapSharedBuffer, VirtIo->FreeSharedPages }
