4.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Michal Kalderon <michal.kalde...@cavium.com>
[ 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")
