Also, the net/ipv4/ipconfig.c definition
seems a lot more sensible as it uses endian
specific types

struct bootp_pkt {		/* BOOTP packet format */
	struct iphdr iph;	/* IP header */
	struct udphdr udph;	/* UDP header */
	u8 op;			/* 1=request, 2=reply */
	u8 htype;		/* HW address type */
	u8 hlen;		/* HW address length */
	u8 hops;		/* Used only by gateways */
	__be32 xid;		/* Transaction ID */
	__be16 secs;		/* Seconds since we started */
	__be16 flags;		/* Just what it says */
	__be32 client_ip;		/* Client's IP address if known */
	__be32 your_ip;		/* Assigned IP address */
	__be32 server_ip;		/* (Next, e.g. NFS) Server's IP address */
	__be32 relay_ip;		/* IP address of BOOTP relay */
	u8 hw_addr[16];		/* Client's HW address */
	u8 serv_name[64];	/* Server host name */
	u8 boot_file[128];	/* Name of boot file */
	u8 exten[312];		/* DHCP options / BOOTP vendor extensions */
};

It'd probably be better to make that struct definition public
and use it instead.
