Intel 1G Network Drivers (e1000, igb, igc)
==========================================

Overview
--------

DPDK provides several poll mode drivers (PMDs) supporting Intel 1 Gigabit
Ethernet controller families. These include:

*   e1000 – Intel 8254x family devices, including QEMU e1000 emulation.
*   e1000e – Intel PRO/1000 PCI‑Express family (82563/6/7, 82571/2/3/4/7/8/9,
             82583 and I217/I218/I219-based adapters).

These drivers follow similar design principles and capabilities and are grouped
here for clarity.

Supported Hardware
------------------

E1000 Devices
~~~~~~~~~~~~~

The e1000 Linux base driver supports the Intel® PRO/1000 PCI and PCI‑X
family of Gigabit Ethernet controllers. Supported devices include:

*   Intel 82540, 82541, 82545, 82546
*   QEMU ``e1000`` emulated NIC

E1000e Devices
~~~~~~~~~~~~~~

The e1000e Linux base driver supports the Intel PRO/1000 PCI‑Express family
including:

*   82563/82566/82567 series
*   82571/82572/82573/82574/82577/82578/82579 series
*   82583-based adapters
*   I217, I218 and I219 Gigabit Network Connections

Driver Notes
~~~~~~~~~~~~

*   e1000 – supports PCI/PCI‑X Gigabit adapters.
*   e1000e – supports PCI‑Express Gigabit adapters.

Both drivers are widely used across physical and virtualized environments.
