  There are 3 kind of link data in ethdev:
	- capabilities (rte_eth_dev_info)
	- configuration (rte_eth_conf)
	- status (rte_eth_link)

A bit-field is used for capabilities (rte_eth_dev_info.speed_capa) and
configuration (rte_eth_conf.link_speeds).
Bits are defined in ETH_LINK_SPEED_*.

Some numerical (ETH_SPEED_NUM_*) and boolean (ETH_LINK_*) values
are used for the link status (rte_eth_link.*).

There was a mistake in the comment of rte_eth_link.link_autoneg,
suggesting ETH_LINK_SPEED_[AUTONEG/FIXED] which are 0/1,
instead of ETH_LINK_[AUTONEG/FIXED] which are 1/0.

The drivers are fixed to use ETH_LINK_[AUTONEG/FIXED].

Fixes: 82113036e4e5 ("ethdev: redesign link speed config")

These three drivers changes from "fixed" to "autoneg", intentional?

Yes.
These are virtual ports, so fixed/autoneg does not really makes sense.
I think autoneg is more fuzzy so more appropriate :)
Anyway, the value is not changed, because
	ETH_LINK_SPEED_FIXED = ETH_LINK_AUTONEG = 1
