GSOC 2015 - NE2000 emulation in bhyve Status

[Alex Teaca]

Hi,

I've started the implementation of the NE2000 module. At the moment the ED
driver is able to probe the emulated device (RealTek 8029) and add it as a
network interface.

Some of the features which are implemented:
- implement some logging support
- clone the /usr/src/sys/dev/ed/if_edreg.h register interface from the ed
driver into the bhyve tree sources
- implement the NE2000 registers support and an API to access the NIC
registers (get and set by offset)
- design and implement the Remote DMA protocol so the ED driver can store
and load from the NIC's RAM memory

Thanks,
Alex
