You can do 24x10G - that's the default config.  It requires PIC-level
speed configuration instead of port-level.

One odd thing though, it isn't just about bandwidth; you can do (at
least according to the configurator tool):

PIC0: 100G 100G 4x10G 4x10G
PIC1: 10G x 8

However, you can't change both of the 100G ports to 40G, you get an
error "Not enough MACs left on asic EA-0".

I wish there was better documentation on exactly what is going on with
that.
