So it is sending packets but not getting the response.

Yes. To clarify my report: client is sending ARP requests, server is 
sending ARP responses, and then either the client is totally ignoring 
them or perhaps indeed updating its ARP table but then say immediately 
expiring the ARP entry. This only happens with lpxelinux.0. Any other 
things I should try or other data I can provide to assist?

Seems like a deaf client.  Interestingly enough, the flags value is
the same as on those other Dells.

With everything else from 6.03-pre18, try this binary (xzip-compressed):
