[PATCH v1 net 0/2] fix shared vcap_props reference

[Colin Foster]

Felix vcap_props get statically allocated at the file scope, while the
felix / ocelot instances get dynamically allocated at initialization. If
there's more than one instance, each instance will be writing over the
same vcap_props memory region, which would lead to corruption.

I don't have any hardware to confidently test the vcap portions of
Ocelot / Felix, so any testers would be appreciated.

Also, I believe the memcpy of a structure array should be
architecture-portable, but I'm not 100% confident there, so that might
be an area of extra scrutiny.
