Thanks. I was doing the same experiment on few switches, i could get hold of and this is the result:

Cisco Switch catalyst 2950 : Completely ignoring the packet, so validations are proper.

Netgear FSM726V3 : Hello timer is validated and is propagated as 10 instead of 255 ( which i sent) other max age and forward delay still it accepts as 255. 

DLINK-DES-3026 : No validation done and accepts all as 255 ( max age, forward delay and hello timer)

In both Netgear and Dlink the message age is changed to 16, which i am not sure why it has happened ? 

my setup is simple
