The caps get API needs to be similar to rx adapter caps get i.e. it needs to
have the eth_port_id as a parameter so that the underlying event dev driver can
expose INTERNAL PORT capability as not all ethdev drivers have the capability
to interact with the eventdevs internal port.
rte_event_eth_tx_adapter_caps_get(uint8_t dev_id, uint16_t eth_port_id,
uint32_t *caps);
Hi Pavan,
Is querying the INTERNAL PORT on a per ethdev basis useful to the
application ?
For e.g., the txa_init() function in the adapter implementation can only
decide to use the internal port if it is supported for all ethdevs,
hence I left that upto the eventdev PMD to decide - i.e., it could
iterate across txa->dev_count eth devices to make that determination.
For caps in general, I agree it makes sense to pass in the ethdev, but
the INTERNAL PORT didn't seem useful on a per ethdev basis.
We could also replace caps_get with something like a
rte_event_eth_tx_adapter_internal_port_check(dev_id) and add a per
ethdev caps if needed later.
Thanks,
Nikhil
