关于K2_STK_DSP里的GE例程接收数据包的MAC地址问题

你们好！我现在在K2E开发板上跑K2_STK_DSP里的GE例程，2-8口我均设置为GE_PORT_NOT_USED，1口设置为ETHERNET_AUTO_NEGOtiAT_SLAVE, GE_PORT_CABLE_CONNECT, ETHERNET_LOOPBACK_DISABLE
DSP往PC发送数据包，我修改了Fill_EMAC_header里的Source_MAC_address和Dest_MAC_address，把88:88:88:00:00:01修改成88:88:88:00:05:55，把88:88:88:00:01:01修改成88:88:88:00:03:33，在PC上用wireshark抓取能成功抓到，如下图所示：

但PC往DSP发送数据包时，我是用xcap软件建立一个数据包发送的，但是只有数据包源MAC地址为88:88:88:00:00:01，目的MAC地址为88:88:88:00:01:01时，DSP才能收到，下列几张图阐述上述情况：
首先是xcap软件建立数据包的图：

建立了两种数据包，第一种数据包（第一行）源MAC地址为88:88:88:00:00:01，目的MAC地址为88:88:88:00:01:01，第二种数据包（第二、三、四行）修改了MAC地址
当发送第一种数据包时，程序打印信息如下所示：

CPSW_port0.TxMCastFrames =14
CPSW_port0.TxOctets =7981
CPSW_port0.Frame64 =13
CPSW_port0.Frame65t127 =54
CPSW_port0.Frame128t255 =4
CPSW_port0.Frame1024tUp =1

CPSW_port1.NetOctets =16191

从加粗及下划线部分可以看出：第一种数据包到达P1口后全数传到了P0口，进而传进DSP核
但是当发送第二种数据包时，程序打印信息如下所示：

从加粗及下划线部分可以看出：第二种数据包到达P1口后就全部被丢弃了，只有系统自发的多播包和广播包到达P0口
这说明只有发送给DSP的数据包MAC地址符合P0、P1口的MAC地址时才能被传输进DSP内部，但是DSP发送数据包到PC时数据包的MAC地址并不符合P0、P1口的MAC地址也成功传输出去了，我想请问该怎么设置才能使得DSP能接收到不符合P0、P1口MAC地址的数据包呢？
