From 77dd550e5547846604ff6f90c4dc6bba4414e485 Mon Sep 17 00:00:00 2001 From: Andy Grover Date: Mon, 22 Mar 2010 15:22:04 -0700 Subject: RDS: Stop supporting old cong map sending method We now ask the transport to give us a rm for the congestion map, and then we handle it normally. Previously, the transport defined a function that we would call to send a congestion map. Convert TCP and loop transports to new cong map method.
