Also, the switch configuration (swconfig) is not working as
expected (when
using r24328). The VLANs for LAN (eth0.1) and WAN (eth0.2) are not
configured properly by default (i.e. WAN port is on one of the LAN
ports).
Modifying the swconfig in '/etc/config/network' seems to have no
effect. Is
this a bug or has swconfig not been implemented yet for ramips?
I haven't had time to review the ramips eth/esw drivers (ramips.c,
ramips_esw.c) to identify the problem yet. I was hoping one of the
ramips
driver developers (John Crispin <blogic> and/or Gabor Juhos
<juhosg>) could
take a look at this and provide some insight. Thanks for your
contributions
to this.
There is no support for swlib in ramips_esw driver - it should be
rewritten to support it.
Thanks, that explains why swconfig doesn't work for ramips.
And this is real problem because, e.g. Belkin board I have has
external switch, and there is no other way (at least with existing
code) except modifying ramips_esw and partially braking ramips
target
to make it work correctly. See my patches from this thread:
https://forum.openwrt.org/viewtopic.php?id=21998 for example.
Hopefully me or Juhos or someone else will have time to rewrite
ramips_esw to support swlib. I see no other right way to do it. But
maybe I'm blind.. :)
Is there anyone working on this? I can take a look at it if no one
is working on it.
Thanks,
Layne
I managed to find a solution to my VLAN issue. It looks like the VLAN
configuration is hard-coded in ramips_esw.c, but the definitions are
incorrect for the HW550-3G. Using the r24328 driver (as discussed
before), I patched it for the HW550-3G:

}
This is only a temporary solution (it's a hack just for the
HW550-3g)... but at least my VLANs are configured properly now. We
should try to get swconfig support into the ramips_esw driver.
There's still the problem with the latest trunk eth/esw drivers not
working (at least for this board). I will try to find the issue when I
have time.
Thanks,
Layne
