NET_PACKET_GSO structure (gsotypes.h)
The NET_PACKET_GSO structure contains Generic Segmentation Offload (GSO) information for a packet.
Syntax
typedef struct _NET_PACKET_GSO {
union {
struct {
UINT32 Mss : 20;
UINT32 Reserved0 : 12;
} TCP;
struct {
UINT32 Mss : 20;
UINT32 Reserved0 : 12;
} UDP;
} DUMMYUNIONNAME;
} NET_PACKET_GSO;
Members
DUMMYUNIONNAME
A union that contains the TCP and UDP member.
DUMMYUNIONNAME.TCP
A structure that holds the TCP GSO information.
DUMMYUNIONNAME.TCP.Mss
The maximum segment size (MSS) for TCP segments.
DUMMYUNIONNAME.TCP.Reserved0
Reserved for system use. Clients must not read or write this member.
DUMMYUNIONNAME.UDP
A structure that holds the UDP GSO information.
DUMMYUNIONNAME.UDP.Mss
The MSS for UDP segments.
DUMMYUNIONNAME.UDP.Reserved0
Reserved for system use. Clients must not read or write this member.
