[PATCH 0/7] Infiniband support in DHCP client

This patch series is part of an effort to bring Infiniband network
booting to OpenPower firmware. It adds support in udhcpc for longer
hardware addresses, non-MAC hardware types, and sending DHCP requests on
Infiniband interfaces.

This series does not support PKEYs/subnets due to the additional
complexity of gathering and storing the necessary broadcast address. It
also does not automatically add the industry-standard client identifier;
this should be added as an option when executing udhcpc.

This series has not been fully tested yet; only the v4 DHCP client has
been lightly tested to verify new functionality. Due to the hardware
available at the time of writing and testing, this series is intended to
be applied to the 1_29_stable branch. Forward porting is likely
straightforward but has not been attempted.

Daniel M. Weeks (7):
  udhcpc: Add IB broadcast addr
  udhcpc: Generic hardware address support
  udhcpc: Use getifaddrs for udhcp_read_interface
  udhcpc: Store hardware address length and type
  udhcpc: Support sending DHCP requests on IB
  udhcpc: Init DHCP headers with the correct htype
  udhcpc: Support gathering Infiniband HW address
