The problem that IPv6 address not catched by this function.
There is ip_dev_find function in the kernel for IPv4 protocol, but no analog
for IPv6.
The solution is to use ipv6_chk_addr function for each network device found in
the system.
The small problem that the same action ( ip_dev_find ) executed in another
place ( addr_resolve_local ),
so it may be better write local, static no exported ipv6_dev_find function and
used it
from addr_resolve_local and rdma_translate_ip instead write the same code twice.
