Yes - you're correct.  I assumed that the HH was at the start of the private
data, but the BSDH should go there.  To fix this, I think we'll want to add bsdh
in struct sdp_hh in cma.c. 

struct sdp_hh {
	u8 bsdh[16];
	u8 sdp_version;
	u8 ip_version;	/* IP version: 7:4 */
	u8 sdp_specific1[10];
	__u16 port;
	__u16 sdp_specific2;
	union cma_ip_addr src_addr;
	union cma_ip_addr dst_addr;
};
