EFI_UDP6_RECEIVE_DATA Struct Reference

Data Fields
EFI_TIME	TimeStamp
EFI_EVENT	RecycleSignal
EFI_UDP6_SESSION_DATA	UdpSession
UINT32	DataLength
UINT32	FragmentCount
EFI_UDP6_FRAGMENT_DATA	FragmentTable [1]

Detailed Description

EFI_UDP6_RECEIVE_DATA is filled by the EFI UDPv6 Protocol driver when this EFI UDPv6 Protocol instance receives an incoming packet. If there is a waiting token for incoming packets, the CompletionToken.Packet.RxData field is updated to this incoming packet and the CompletionToken.Event is signaled. The EFI UDPv6 Protocol client must signal the RecycleSignal after processing the packet. FragmentTable could contain multiple buffers that are not in the continuous memory locations. The EFI UDPv6 Protocol client might need to combine two or more buffers in FragmentTable to form their own protocol header.
