[PATCH 4.15 03/47] qed: Fix MPA unalign flow in case header is split across two packets.

[Greg Kroah-Hartman]

4.15-stable review patch.  If anyone has any objections, please let me know.

[ Upstream commit 933e8c91b9f5a2f504f6da1f069c410449b9f4b9 ]

There is a corner case in the MPA unalign flow where a FPDU header is
split over two tcp segments. The length of the first fragment in this
case was not initialized properly and should be '1'

Fixes: c7d1d839 ("qed: Add support for MPA header being split over two tcp 
packets")
