[U-Boot-Users] Ping issue

[Vidya S]

Hi,

   I am using smc91111.c driver of u-boot. all my network functionalities are working well.
i am able to ping an other ip address and i get a message that the host is alive or not. 

Only problem is, when someone pings the target ip (my network card ip), it says destination not reachable. 
Is this really a problem? if so, pls help me solving it.

regards
vidya

There is no ICMP reply support in current u-boot.

I have some custom patches that can do that
but I haven't yet submitted, and even when I will
there is no guarantee that they'll make it, since
they require pretty big changes to the networking code.

vidya,
    Ping is working properly in u-boot-1.0.0 and further versions.
I didnt faced any such problem in the smc91111.

I can imagine the magnitude of the required changes, and I agree that
it's very unlikely that I would accept such a big reorganization  for
such a little gain.

Well, obviously that the ping works is only a small
side-effect.

Anyway, since u-boot is GPL, I have to at least offer
my changes to the community.
If they are rejected is no big deal...

I see. So I better keep my mouth shut and have a  look  at  the  code
before whining. Sorry.

So far your contributions were well accepted, I think.

Hello Wolfgang,

There hasn't been much more discussion on this possible contribution to 
the U-Boot mainline. And I haven't had a chance to look at the latest 
CVS source - was a patch ever submitted for ICMP reply support?

In your previous message, it looked like the patch would not be accepted 
if it required a massive code overhaul.

Thank you and best regards, Andy

I haven't seen any.

No, this is not exactly what I said:

This is not a problem, but how it's implemented.
