OPENVPN_PACKET *OvsParsePacket(UCHAR *data, UINT size)

if (ret->NumAck > OPENVPN_MAX_NUMACK)
{
Debug("___ERR4: OvsParsePacket. data=%p, size=%u ret->NumAck=%d\n", data, size, ret->NumAck);
goto LABEL_ERROR;
}

// Read the Packet ID Because in the case of other than ACK
if (size < sizeof(UINT))
{

goto LABEL_ERROR;
