Mellanox with switches like the SN2700. I don't know how open is the
hardware documentation, but they are pushing support for their ASIC
directly into Linux (look at drivers/net/ethernet/mellanox/mlxsw). They
are also contributing to the switchdev framework which will at some
point allow transparent acceleration of the Linux box (switching,
routing, tunneling, firewalling, etc.), as we already have with

The datasheet is quite scarce. There is a 88k L2 forwarding entries but
no word for L3. Buffer sizes are not mentioned. But I suppose that
someone interested would be able to get more detailed information.
