[openib-general] [PATCH] SDP: add <linux/if_arp.h>

[Roland Dreier]

In upstream kernels, it seems that networking headers have been
rejiggered so that <linux/if_arp.h> no longer gets included implicitly
into sdp_link.c.  Since sdp_link.c uses the ARPHRD_INFINIBAND symbol,
we need to include it explicitly.
