[systemd-devel] [PATCH] sd-dhcp-client: support non-Ethernet hardware addresses

Fri Sep 26 13:15:37 PDT 2014
Like Infiniband. See RFC 4390 section 2.1 for details on DHCP
and Infiniband; chaddr is zeroed, hlen is set to 0, and htype
is set to ARPHRD_INFINIBAND because IB hardware addresses
are 20 bytes in length.
