[FS#937] Busybox ping6 fail. Ula prefix

[LEDE Bugs]

The following task has a new comment added:

FS#937 - Busybox ping6 fail. Ula prefix
User who did this - Rodrigo Sansana (ssn17x)

----------
Add fd10::1/64 to br-lan to replicate the problem

- traceroute selects the 2001::x addr as ip source
- ping not

If i use 'ping -6 -I 2001:x' it works

"
Just a divagation
Ipv6 is perfect as global address
fe80 and fd prefix has strange bugs on general
