[ECOS] Ethernet Link status

[ECOS] Ethernet Link status

[Emmanuel Coullien]

Hi,

I tryed to know what was the Ethernet link status from the application
level using ioctl but I think it miss some code in the BSD_TCPIP
package to pass over this layer.
In fact, it misses the case for SIOCGSTATUS in the BSD_TCPIP layer, so
 I had to add the lines below in the if.c file and now we can get the
link status.
 	case SIOCGIFSTATUS:
	case SIOCGIFSTATS:
	case SIOCGIFSTATSUD:
		if (ifp->if_ioctl == 0)
			{
			return (EOPNOTSUPP);
			}
		return ((*ifp->if_ioctl)(ifp, cmd, data));

What do you think about these modifications. Is it possible to patch
it in eCos ?

Thanks. I've applied a similar, but equivalent, change.

In the future, if you find a change that you think needs to
be made, send a proper patch, along with a ChangeLog entry,
to ecos-patches@ecos.sourceware.org.  We'll discuss and
consider the change, and apply as required.

[ECOS] ethernet link status

[Ambrogio]

Dear all

On application using eCos it's possible to know the ethernet phisical
link status (eth0 or eth1)? It's possible to know if the link is active
(or down) whitout send packet over the link?

I so, I think it is a stupid question but afther two working day have no
solution for this problem.

Thanks in advance
