=E2=80=8BVALE is part of the netmap kernel module, the only thing you need
to know to use it is port names:
you can have multiple switch instances with multiple ports each,

valeX:Y means port Y on switch X, X and Y are arbitrary strings
with the constraint that the whole name must fit 15 characters.

Details in the netmap manpage
