[dpdk-dev,v3,1/6] ethdev: add an field for querying hash key size
Commit Message
To support querying hash key size per port, an new field of
'hash_key_size' was added in 'struct rte_eth_dev_info' for storing
hash key size in bytes.

v2 changes:
* Disabled the code changes by default, to avoid breaking ABI compatibility.
v3 changes:
* Moved the newly added element right after 'uint16_t reta_size', where it
was a padding. So it will not break any ABI compatibility, and no need to
disable it by default.

Neil, what is your opinion?
Do you ack that this technique covers every ABI cases?
