[Qemu-devel] [RFC PATCH v2 10/10] net: Introduce e1000e device emulation |
|

From: Dmitry Fleytman <address@hidden>
This patch introduces emulation for the Intel 82574 adapter, AKA e1000e.
This implementation is based on the e1000 emulation code, and
utilizes the TX/RX packet abstractions initially developed for the
vmxnet3 device. Although some parts of the introduced code are
common with the e1000, the differences are substantial enough so
that the only shared resources for the two devices are the
definitions in hw/net/e1000_regs.h.
Similarly to vmxnet3, the new device uses virtio headers for task
offloads (for backends that support virtio extensions). Usage of
virtio headers may be forcibly disabled via a boolean device property
"vnet" (which is enabled by default). In such case task offloads
will be performed in software, in the same way it is done on
backends that do not support virtio headers.
The device code is split into two parts:
1. hw/net/e1000e.c: QEMU-specific code for a network device;
2. hw/net/e1000e_core.[hc]: Device emulation according to the spec.
The new device name is e1000e.
Intel specification for 82574 controller is available at
http://www.intel.com/content/dam/doc/datasheet/82574l-gbe-controller-datasheet.pdf
