[dpdk-dev] [PATCH v2 29/29] net/vmxnet3: use eal I/O device memory read/write API

[Jerin Jacob]

From: Santosh Shukla <santosh.shukla at caviumnetworks.com>

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.
