+Subject: [TCP]: BIC coding bug in Linux 2.6.13
+
+From: Stephen Hemminger <shemminger@osdl.org>
+
+Please consider this change for 2.6.13-stable   Since BIC is
+the default congestion control algorithm, this fix is quite
+important.
+
+Missing parenthesis in causes BIC to be slow in increasing congestion
+window.
+
+Spotted by Injong Rhee.
