[libfabric-users] Scatter/Gather send operations

I would like to accelerate my software (NetIO if anybody remembers) by
using scatter/gather operations like fi_sendv.
I have two questions about that:
1) For the verbs provider it looks like scatter/gather support is very
limited. By default a vector can only contain up to 4 entries. How far
can I push that? I would like put there in the order of 100s of entries.
2) Concerning memory registrations. All iovec entries would come from an
address range which can span maybe up to 4 GB. Do I have to register
every iovec entry, or would be sufficient to do one memory registration
of the large 4 GB memory region?
Thanks for your help.
