I am trying to make  dhcp 4.4.2b1 work on Mellanox Infiniband for IPoIB.

  1.  Seems like , bpf does not have support for IPoIB as family passed in zero so IPoIB driver returns error.
  2.  I tried using sockets for DHCP server and send is successful (returning exact number of bytes in packet) but I do not see packet in IPoIB driver.
  3.  Able to receive DHCP broadcast request to DHCP server code (user space)
  4.  Ping is working fine (statically assign IP address) and seems like issue with DHCP broadcast replies in DHCPOFFER (same code works with Linux)

Any help will be appreciated .
