[dpdk-dev] [PATCH] net/e1000: build on Windows

[William Tu <u9012063@gmail.com>]

This patch enables building the e1000 driver for Windows.
I tested using two Windows VM on top of VMware Fusion,
creating two e1000 devices with device ID 0x10D3,
verifying rx/tx works correctly using dpdk-testpmd.exe
rxonly and txonly mode.

Warning! port-topology=paired and odd forward ports number, the last port will p
air with itself.
