/**

Callback function that is invoked when the PXE Base Code Protocol is about to transmit, has
|
|
received, or is waiting to receive a packet.
|
|
|
|
This function is invoked when the PXE Base Code Protocol is about to transmit, has received,
|
|
or is waiting to receive a packet. Parameters Function and Received specify the type of event.
|
|
Parameters PacketLen and Packet specify the packet that generated the event. If these fields
|
|
are zero and NULL respectively, then this is a status update callback. If the operation specified
|
|
by Function is to continue, then CALLBACK_STATUS_CONTINUE should be returned. If the operation
|
|
specified by Function should be aborted, then CALLBACK_STATUS_ABORT should be returned. Due to
|
|
the polling nature of UEFI device drivers, a callback function should not execute for more than 5 ms.
|
|
The SetParameters() function must be called after a Callback Protocol is installed to enable the
|
|
use of callbacks.
|
|
|
|
@param This The pointer to the EFI_PXE_BASE_CODE_CALLBACK_PROTOCOL instance.
|
|
@param Function The PXE Base Code Protocol function that is waiting for an event.
|
|
@param Received TRUE if the callback is being invoked due to a receive event. FALSE if
|
|
the callback is being invoked due to a transmit event.
|
|
@param PacketLen The length, in bytes, of Packet. This field will have a value of zero if
|
|
this is a wait for receive event.
|
|
@param Packet If Received is TRUE, a pointer to the packet that was just received;
|
|
otherwise a pointer to the packet that is about to be transmitted.
|
|
|
|
@retval EFI_PXE_BASE_CODE_CALLBACK_STATUS_CONTINUE if Function specifies a continue operation
|
|
@retval EFI_PXE_BASE_CODE_CALLBACK_STATUS_ABORT if Function specifies an abort operation
