Here is an ack, in case you need it. Please feel free to add it to v4 if you
make it (i.e. dropping the leading _).

FWIW, the NIC hardware (Cisco VIC) does autonegotiate. But, the link
settings (autoneg/fixed/10/25/40) are controlled by a management
entity (e.g. UCS manager). The drivers including the netdev enic
driver cannot change them and currently do not know if the current
speed has been autonegotiated or fixed by admin. So, they simply
report the current link speed as fixed. I know, it is a little
unconventional.
