That maybe be difficult, but will definitely try it out to see if the
problem persists.

I already use that, but that is not exactly what SO_BINTODEVICE does.
I have 2 default gateway (mgmt for ssh etc. and data) and I have
experienced cases where the data goes out of the wrong interface
depending on which default gw gets added first in routing table. This
is in spite of explicitly using the bind() call. It seems like the
only way to force the usage of a particular interface is to use
SO_BINDTODEVICE.
