The current approach for finding a device's capability flags is to use
ib_query_device().  If you want to use that and cache the result in
IPoIB that's fine.  Or if you want to move device_cap_flags into
struct ib_device that's OK too I guess, although I think in that case
you need some justification that there's never a need to query things
at runtime (it seems OK to me but I haven't thought it through in detail)
