(57) Abstract :
Described herein is a system having a multi-host Ethernet controller (102) configured to provide communication and control
between two or more independent host processors (104) and a network device. In one implementation, the multi host Ethernet
controller (102), having an integrated L2 switch (110) to enable a plurality of independent host systems to access same physical
gigabit network port concurrently. Each host processor (104) sees the controller as PCI based independent network controller and
accesses the controller using its own mini-port driver. The common programming parameters such as Link Speed or Inter Packet
Gap (IPG) are programmed by a virtualization engine. Packets from network (LAN) are switched based on MAC destination
address and sent to corresponding host based on MAC destination address. Packets from each host processor (104) are forwarded
to network interface or other host processor (104) based on MAC destination address.
