[SUGGESTION] Interface no up and/or running

[Matteo]

Hi all,
until today I used olsrd-0.6.0 for WiFi multi-hop, but today I compiled the last stable version 0.6.5 .
I noticed an error when I ran olsrd: Interface no up and running.
So, I read the ifnet.c and I figured out a few change between this last version and 0.6.0 .

The problems were in chi_if_up and chi_if_changed function , when it checks if the wifi is up and running.
Then, for WiFi connection I suggest to modify if(((ifs.int_flags & IFF_U) == 0) || ((ifs.int_flags & IFF_RUNNING)==0)) => if((ifs.int_flags & IFF_U) == 0) in both the above functions.

This check if(((ifs.int_flags & IFF_U) == 0) || ((ifs.int_flags & IFF_RUNNING)==0)) works with ethernet because you can set ifs.int_flags with IFF_RUNNING

Best,
Matteo

Do you want to say that Olsrd-0.6.5 does not work with Ethernet interfaces?

Thats definitely not true.

No, I want say it works with ethernet, instead this if(((ifs.int_flags & IFF_U) == 0) || ((ifs.int_flags & IFF_RUNNING)==0))
is always true with WiFi interface.

I tried several WiFi drivers and Kernel and always there was Interface error.

I would guess there are thousands of people running olsrd on wifi
interfaces without any interface error.

Do NOT push this change, there must be something different going wrong.
