[dpdk-dev] [PATCH] eventdev: add experimental tag back

[Nikhil Rao]

Add the experimental tag back to the Rx event adapter callback
and the Rx event callback register functions. This patch also
adds the experimental tag in the callback register
function definition and adds the function to the EXPERIMENTAL
section of the map file, these were missing previously.

[dpdk-dev] [PATCH v3] eventdev: add experimental tag back

[Nikhil Rao]

Add the experimental tag back to the Rx event adapter callback,
the Rx event callback register and the Rx event adapter statistics
retrieval functions due to API change to be proposed in a
future patch.

This patch also adds the experimental tag to these
function definition and adds the functions to the EXPERIMENTAL
section of the map file, these were missing previously.

[dpdk-dev] [PATCH v4] eventdev: add experimental tag back

[Nikhil Rao]

Add the experimental tag back to the Rx event adapter callback,
the Rx event callback register and the Rx event adapter statistics
retrieval functions due to an API change to be proposed in a
future patch.

This patch also adds the experimental tag to these
function definitions and adds the functions to the EXPERIMENTAL
section of the map file, these were missing previously.

Fixes: 80bdf91dc8ee ("eventdev: promote adapter functions as stable")
Cc: jerinj@marvell.com

Signed-off-by: Nikhil Rao <nikhil.rao@intel.com>
---

v4:
* move rte_event_eth_rx_adapter_cb_register to the experimental section of the map file
* add EXPERIMENTAL to the MAINTAINERS file

v3:
* add experimental tag to the Rx event adapter stats retrieval function

v2:
* add patch explanation to commit message
