From b443307ad3c5cff2957c00338eaf3239261801f1 Mon Sep 17 00:00:00 2001 From: Pablo de Lara Date: Mon, 15 Dec 2014 13:41:46 +0000 Subject: [PATCH] ring: fix return type in enqueue and dequeue burst functions Enqueue and dequeue burst functions always return a positive value (including 0), so return type should be unsigned, instead of int. Fixed also API doc for one of the functions.
