[LEDE-DEV] mwan3 not working

[Mauro Mozzarelli]

Thanks Yousong, Merci Etienne,


I updated and rebuilt with the fix r4117 and I already communicated to 
Etienne that this fixes MWAN Interface Systemlog (this now shows), but 
both my interfaces remain marked as offline and red, when they are in 
fact up and connected.

Backing to r4041 (which is the last I had built and saved previously) 
resolves the issue for the time being

I have seen in the issue log that Etienne pointed me to that he updated 
the "ip" command path.

There are other errors being logged by uhttpd due to missing /usr/bin/ip.

When I create a symbolic link:

  /usr/bin/ip -> /sbin/ip-tiny

The mwan3 problem seems to go away so there must be something else 
looking for /usr/bin/ip that Etienne might have missed.


I wonder if other packages will have the same issue as it is common 
practice to hardcode binaries' full path in scripts rather than setting 
the PATH variable.
