Yes, I've been working on that one already.
What I'll be doing is to read in the sge count during 'map_sgl' and
store this value internally (in ->iov_cnt). And during unmap I'll be
using this value instead of the frame-provided one.
That way we'll be checking the sge_count field only once when we slurp
in the entire frame.
Note the flags too. Perhaps it's easier to simply copy the entire frame
header...
