It can't change the route table when you've given it no address:
IE. ifconfig em0 HOSTNAME mtu 9000 will update it just fine.

Hello,
As the subject says, I'm trying to enable jumbo frames on running
machine by setting
ifconfig em0 mtu 9000 by hand, but nothing changed, and I've fount
that when I list
the routing table with the MTU column it shows the connected routes
still with MTU 1500.
Is this supposed to work this way? I understand that making ifconfig
touch the routing table is ugly hack, but maybe the routing code can
be notified for interface changes by some other mechanism?
btw, this is on 7-STABLE with if_em(4) interfaces.

Hi Jack,
Yes, I understand that, It just looked logical to me to update the
existing entries (directly attached) if no address is given, so one
can use the mtu knob alone.
Anyways, one rarely touches the mtu alone and this not a real problem,
I've just tried to enable jumbo frames on two running machines with
just the ifconfig em0 mtu 9000 line and wondered why it does not work
for a minute.
Thanks!
