actually it makes no difference, the relevant route entries are stored in
the T5 chip
cxgbetool tells me I have 532447 entries right now
for fib 0 anyway, I have a similar number of entries (a couple more due to
pinned ipv6 not triggered to the card), but other than management port for
ssh, snmp, webgui and netflow, only 180kpps for a trunked copper dmz
segment is actually forwarded at fib. everything else is done on the card
