> The modify field action description inside "Generic flow API (rte_flow)"
> documentation, lists all operations supported for a destination field.
> In addition, it lists the values supported for a encapsulation level
> field.
> 
> Before the lists, in both cases, miss a blank line causing them to look
> regular text lines.
> 
> This patch adds the blank lines.
