I am not so sure about this change either.

->sc_max_sge is used to limit the number of segments used during sends,
currently in this code. Grep for where it is used.
Therefore, if anything, the correct thing to do would be to retain the
first line rather than the second line.
Someone who actually works on this code and understands it should
really take a close look at this before anyone even thinks about
applying this patch.
