Those 3 entries can be gathered under a single item about the dlb2 driver.
Like:
* **Updated dlb2 eventdev driver.**
* Added API ``rte_pmd_dlb2_set_port_params`` to support delayed token...
...
* Introduced dynamic HL (History List) feature for DLB device...
...
etc...
Besides, those doc updates should be split and go with the patches
that introduce the features.
This comment applies to the previous doc patch too.
