From: Mike Marciniszyn Date: Tue, 11 Jan 2011 01:42:20 +0000 (-0800) Subject: IB/qib: UD send with immediate receive completion has wrong size X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=c7665e5a6988450a6cc19c2dc1dff4d290077614;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git IB/qib: UD send with immediate receive completion has wrong size The code to generate receive completion entries for UD send with immediate contains the wrong payload length. This is because when the code to compute the payload size was moved, the value of hdrsize didn't get moved too. The fix is to update tlen directly.
