The code in vnetusba.c (and probably in its pcmcia counter part) never
sets shared key as it was supposed to do, at least from my understanding
of the man pages, when ones includes "restricted" keywork on encryption
configuration. The attached patch seems to solve it. I performed some
very quick tests after modifying the code and it worked with both open
and rescricted setups. I will forward it to the driver maintainer with
some other suggestions.
