9fb98e3e05 lib/socket: Fix improper use of default interface speed
_get_interfaces() function from interfaces.c uses if_speed
variable to store interface speed and is initialized with a
default value at start. But if_speed populated via one
iteration for a specific IP address will be treated as the
default value for next iteration which is wrong. Therefore
change is to move the initialization cum declaration of
if_speed inside iteration of IP addresses loop.

abe5afc580 Fix bug with Samba not recognising an 6to4 IPv6 interface.
"The 6to4 interface has the flags IFF_POINTTOPOINT interface but no
ifa_dstaddr as it's not at the IPv6 level a point to point interface
(at least from my understanding), as we don't have a IFF_BROADCAST
flag set (I have the impression that this flag is only set on a
interface that has also an IPv4 address) the first test is not valid
also, which result in a skipped interface."
