From b2d565365e02947699a8e3d594275662a8d00646 Mon Sep 17 00:00:00 2001 From: Alexander Duyck Date: Thu, 20 Nov 2008 00:47:34 -0800 Subject: [PATCH] igb: simplify swap in clean_rx_irq if using packet split This update replaces the xchg calls that were added with a pair of assignments as there is no need for the xchg calls and they were found to cause issues on some architectures.
