just the PHY.

once the target geometry and Foundry is known, SymbioticEDA can do a layout
for around EUR 600,000 (last time i checked).
that is as a *libre* designed PHY where unlike normal PHY licensing from
proprietary companies you pay once per geometry per foundry chip per 32 bit
interface, for SymbioticEDA we would pay once per geometry per foundry.
it'll take around 12 man months.
