Hi Vadym

This is a core feature which needs to be in the first version merged
into the kernel. Basically, the driver first needs to offer 24
individual interfaces which can send and receive packets. The Linux
stack does everything else. You then add offloads, like bridges,
vlans, etc, allowing the hardware to accelerate what Linux is doing.
