Maybe it is a good time to make some order here.
I understand the decision to use flags instead of bit-field. It is better.
However there is a mix here of device capabilities like : RTE_ETH_DEV_INTR_LSC and RTE_ETH_DEV_INTR_RMV
And device attributes like : RTE_ETH_DEV_BONDED_SLAVE and RTE_ETH_DEV_REPRESENTOR.
I don't think they belong together under the genetic name of dev_flags.
Moreover, I am not sure the fact device is bonded slave should be exposed to the application. It should be internal to ethdev and its port iterators.
Finally I think representor port may need more info now (and in the future), for example the associated vf id.
For that, I think it is better it to be exposed as a dedicated struct on device info.

Should be set in the PMD, not in ethdev layer.
