IMHO until there is no proof from a sniffer or some regs dumps the
switch and the router are more suspicious than your NIC or linux box.
Then debugging these other things isn't so much interesting from my
POV ;-)

Anyway, if you only want to get it working (instead of debugging),
it seems you might try moving the dhcp server to the router or maybe
even using two separate servers with their pools - unless I missed
something in your config.
