From 2a272f98619f188efe22119b0415aac6bc34a13f Mon Sep 17 00:00:00 2001 From: Gavin McCullagh Date: Wed, 25 Oct 2006 23:05:52 -0700 Subject: [PATCH] [TCP] H-TCP: fix integer overflow When using H-TCP with a single flow on a 500Mbit connection (or less actually), alpha can exceed 65000, so alpha needs to be a u32.
