From f2c238a0c5e155acd49752c5fb93fb8d8534232b Mon Sep 17 00:00:00 2001 From: Hoang-Nam Nguyen Date: Sun, 5 Nov 2006 21:42:20 +0100 Subject: [PATCH] IB/ehca: Activate scaling code by default Change ehca's Kconfig to activates scaling code as default. After several measurements we saw that this feature prevents dropped packets (UD) in stress situation. Thus, enabling it helps to improve ehca's bandwidth through IPoIB.
