From c7665e5a6988450a6cc19c2dc1dff4d290077614 Mon Sep 17 00:00:00 2001 From: Mike Marciniszyn Date: Mon, 10 Jan 2011 17:42:20 -0800 Subject: [PATCH] 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.
