X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=933e8c91b9f5a2f504f6da1f069c410449b9f4b9;p=openwrt%2Fstaging%2Fblogic.git qed: Fix MPA unalign flow in case header is split across two packets. 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") Signed-off-by: Michal Kalderon Signed-off-by: Ariel Elior Signed-off-by: David S.
