\section NetworkAdapterManagement Network Adapter Management
Network adapters may come and go over the life if a system running
UEFI. The SocketDxe driver uses the driver binding API to manage
the connections to network adapters.
The ::DriverSupported routine selects network adapters that the
socket layer is not using. This determination by the lack of the
tag GUID associated with the network protocol in the
::cEslSocketBinding array. The selected network adapters are
passed to the ::DriverStart routine.
The ::DriverStart routine calls the ::EslServiceConnect routine
to create an ::ESL_SERVICE structure to manage the network adapter
for the socket layer. EslServiceConnect also installs the tag
GUID on the network adapter to prevent future calls from
::DriverSupported. EslService also calls the network specific
initialization routine listed in ESL_SOCKET_BINDING::pfnInitialize
field of the ::cEslSocketBinding entry.
The ::DriverStop routine calls the ::EslServiceDisconnect routine
to undo the work done by ::DriverStart. The socket layer must break
the active network connections, then remove the tag GUIDs from the
controller handle and free ::ESL_SERVICE structure.

This routine walks the cEslSocketBinding array to determines if
the controller is a network adapter by supporting any of the
network protocols required by the sockets layer. If so, the
routine verifies that the socket layer is not already using the
support by looking for the tag GUID listed in the corresponding
