I agree it is a good move to clean up ethdev API.

"ixgbe bypass" should be in the title and the description.
I'll reword to:

doc: announce move of ethdev bypass function to ixgbe API

In 17.05, nine rte_eth_dev_* functions for bypass control,
and implemented only in ixgbe, will be removed from ethdev,
renamed and moved to the ixgbe PMD-specific API.

[dpdk-dev] [PATCH] doc: announce API and ABI change for ethdev

[Zhiyong Yang]

  This is an API/ABI change notice for DPDK 17.11 on redefinition of
port_id. port_id is defined as uint8_t by now, which is just ranged
from 0 to 255. For more and more scenerioes, more than 256 devices are
needed to support for vdev scalability.

  It is necessary for redefinition of port_id to extend from 1 bytes
to 2 bytes. All ethdev APIs and use cases related to port_id will be
changed at the same time.

I think this reads a little better:

This is an API/ABI change notice for DPDK 17.11 announcing the 
redefinition of port_id. port_id is currently defined as uint8_t, which 
is limited to the range 0 to 255. A larger range is required for vdev 
scalability.

It is necessary for a redefinition of port_id to extend it from 1 bytes 
to 2 bytes. All ethdev APIs and usages related to port_id will be 
changed at the same time.

Thanks Remy, of course. Your statement is better. I have a lot of things  to learn
when speaking in English. I hope I can describe things like you, a native speaker. :)
