> * 256x32 SRAM for eth_mac

If that's supposed to hold a full ethernet packet, it's too small for the
standard ethernet frame size:

it needs to be at least 1522 bytes if we don't want to support jumbo frames
(the ethernet fields -- not just the payload -- are needed for full packet
capture like for wireshark):

if we want to support jumbo frames we'll need 9022 bytes:
