From 458a4a7affc617635272e66334e6c005b9fc4fc4 Mon Sep 17 00:00:00 2001 From: Santosh Shukla Date: Wed, 18 Jan 2017 06:51:30 +0530 Subject: [PATCH] net/bnx2x: use I/O device memory read/write API Replace the raw I/O device memory read/write access with eal abstraction for I/O device memory read/write access to fix portability issues across different architectures.
