The maximum amount of unique switching domain is supposed
to be equal to RTE_MAX_ETHPORTS. The current implementation
allows to allocate only RTE_MAX_ETHPORTS-1 domains.

I would keep the indexes same but change how to set the 'domain_id' to
"*domain_id = i + 1;", that makes logic simpler.

Would it be simpler if the invalid domain id value used as UINT16_MAX instead of
'0'? This enables using 'domain_id' as index and prevent this error prone indexing.

And I think it makes sense to start the loop with "i = 0", instead of
'RTE_ETH_DEV_SWITCH_DOMAIN_ID_INVALID', you are walking through the port list,
why to involve the 'RTE_ETH_DEV_SWITCH_DOMAIN_ID_INVALID' here.

Agree.

My concern was not to change the existing RTE_ETH_DEV_SWITCH_DOMAIN_ID_INVALID
definition, which currently is zero. Currently, AFAIK, the switch feature is supported by mlx5
only, other PMDs do not bother to initialize the rte_eth_dev_info-> switch_info structure
(no one sets RTE_ETH_DEV_SWITCH_DOMAIN_ID_INVALID to domain_id field for now).
So, changing the RTE_ETH_DEV_SWITCH_DOMAIN_ID_INVALID from zero might cause
wrong switch capability reporting from PMDs.

I do not know why it was implemented in this way 😊
I just was trying to introduce the minimalistic fix. I'll think how to extend my fix a bit.

I think PMDs shouldn't have to initialize the values that they don't use/care,
otherwise it will be very error prone. Can this be handled in the API level?

Like in 'rte_eth_dev_info_get()', after "memset(dev_info, ..)" set 'switch_info'
as INVALID before dev_ops called. PMD can overwrite this if they want, otherwise
it will stay invalid and I think this is safer.

The maximum amount of unique swutching domain is supposed
to be equal RTE_MAX_ETHPORTS. Current implementation allows
to allocate only RTE_MAX_ETHPORTS-1 domains.

The definition of RTE_ETH_DEV_SWITCH_DOMAIN_ID_INVALID is
changed from 0 to UINT16_MAX, the rte_eth_dev_info_get is
updated to initialize dev_ibfo structure accordingly.
