pnetwork->network.Ssid.SsidLength is a u32 so it would be better to
not truncate the upper bits away.  It's not going to cause a
problem, but its slightly messy.

This is a common problem where people take the type of
iwe.u.data.length and cast to that instead of considering the types
for the data they are comparing.
