DM8168双网口问题

user4546956

修改了内核里的/arch/arm/mach-omap2/devices文件的

static struct platform_device ti816x_emac2_device = {
.name = "eth_offload",
.id = 1,
.num_resources = ARRAY_SIZE(ti816x_emac2_resources),
.resource = ti816x_emac2_resources,
};

.name = "davinci_emac",开启了eth1，驱动也加载好了，ifconfig出来的信息如下：

eth0 Link encap:Ethernet HWaddr 88:C2:55:86:99:86
inet addr:192.168.1.236 Bcast:192.168.255.255 Mask:255.255.0.0

RX bytes:0 (0.0 B) TX bytes:0 (0.0 B)

eth1 Link encap:Ethernet HWaddr 88:C2:55:86:99:87
inet addr:192.168.1.237 Bcast:192.168.255.255 Mask:255.255.0.0

TX packets:0 errors:0 dropped:0 overruns:0 carrier:0

RX bytes:0 (0.0 B) TX bytes:0 (0.0 B)
Interrupt:44

现在的情况是eth0和eth1都可以和pc连接上，但是eth0可以ping通，eth1却ping不通。

两个网口的硬件可以保证是一样的

是使用eth1还需要修改其他地方吗？还是说别的什么问题？请各位大神帮忙分析一下！！

Ben，

你使用的驱动版本是不是比较旧？现在驱动默认两个EMAC都是支持的。

建议升级驱动到git上最新的，http://arago-project.org/git/projects/?p=linux-omap3.git;a=summary

DRK版本是DVRRDK_04.00.00.03

现在是连接eth1 ping的时候，eth1只接收数据，几乎没有发送数据出去，而且奇怪的是lo居然在进行收发数据，网卡信息如下：
