Subject: [dpdk-dev] [PATCH] ixgbe: fix ixgbe PCI access endian issue
Date: Thu, 12 Feb 2015 09:19:50 +0800	[thread overview]
Message-ID: <1423703990-29031-1-git-send-email-xuelin.shi@freescale.com> (raw)

From: Xuelin Shi <xuelin.shi@freescale.com>

ixgbe is little endian, but cpu maybe not.
add necessary conversions.
    rte_cpu_to_le_32(...) for PCI write
    rte_le_to_cpu_32(...) for PCI read.
