When a function call, declaration, or definition spans multiple lines,
you must start the arguments on the second and subsequent lines exactly
at the first column after the openning parenthesis.

Please therefore reindent this properly.

Likewise.

Likewise.

> +			(skb->len & DESC_DATA_MASK) << DESC_DATA_LEN_OFF |
> +			(skb->len & DESC_DATA_MASK) << DESC_BUFF_LEN_OFF);

Likewise.

Likewise.

10,000 udelay(1)'s is a long time, consider changing to usleep() or
similar.

Indentation.

Likewise.

Likewise.
