Docs say:
"The first interface of the correct type (IPv4 or IPv6)
is used for the outgoing connection" (the "interface" option takes a list) -
so that does not seem to be so.


SO_BINDTODEVICE in Linux socket(7) seems relevant, but implies that

might even be restrictive; that if you spec addr "A" for an interface that also
has
a "B" for a different subnet, you won't be able to connect to hosts on that "B"
net.
This feels like something that will differ across network-stack
implementations, too.
Anyone feel like testing it?
