Hi Lee

 /**
  * build_hdr_data - creates L2/L3/L4 header data buffer
- * @hdr_field - bitfield determining needed headers
- * @skb - socket buffer
- * @hdr_len - array of header lengths
- * @tot_len - total length of data
+ * @hdr_field: bitfield determining needed headers
+ * @skb: socket buffer
+ * @hdr_len: array of header lengths
+ * @tot_len: total length of data
  *
  * Reads hdr_field to determine which headers are needed by firmware.
  * Builds a buffer containing these headers.  Saves individual header

The code is:

static int build_hdr_data(u8 hdr_field, struct sk_buff *skb,
                          int *hdr_len, u8 *hdr_data)
{

What about hdr_data? 

 /**
  * create_hdr_descs - create header and header extension descriptors
- * @hdr_field - bitfield determining needed headers
- * @data - buffer containing header data
- * @len - length of data buffer
- * @hdr_len - array of individual header lengths
- * @scrq_arr - descriptor array
+ * @hdr_field: bitfield determining needed headers
+ * @data: buffer containing header data
+ * @len: length of data buffer
+ * @hdr_len: array of individual header lengths
+ * @scrq_arr: descriptor array

static int create_hdr_descs(u8 hdr_field, u8 *hdr_data, int len, int *hdr_len,
                            union sub_crq *scrq_arr)

There is no data parameter.

It looks like you just changes - to :, but did not validate the
parameters are actually correct.
