you could try grepping for "struct if_head" instead. spelling helps.

$ grep if_head *.h
channel.h:	struct if_head	ifhead_;
node.h:	inline const struct if_head& ifhead() const { return
ifhead_; }
node.h:	struct if_head ifhead_; // list of phys for this node
phy.h:LIST_HEAD(if_head, Phy);
phy.h:	inline void insertchnl(struct if_head *head) {
phy.h:	inline void insertnode(struct if_head* head) {

that's all just horribly ugly. So, if_head is really a faked-up 
pointer to a LIST_HEAD structure, as defined in ~/ns/lib/bsd-list.h.
