The device's carrier status is controlled via the functions
netif_carrier_on() and netif_carrier_off().  These set or clear a bit
indicating the carrier (aka lower level link) is down, and if the state
changed, they fire off a routing netlink event.

Add a call to netif_carrier_off() before register_netdev() so that the
newly created device will be set to carrier down.  Then when the carrier
comes up for the first time, a netlink event will be generated, as the
carrier changed from down to up.  Otherwise the initial carrier up will
appear to be changing the status from up to up, and so no event is
generated since that's not a change.

It appears to be a pretty simple issue in the driver that wasn't discovered

When NETIF_F_LLTX is set, the atlx driver will use a private lock.
But in recent kernels this implementation seems redundant and
can cause problems where AF_PACKET sees things twice. Since
NETIF_F_LLTX is marked as deprecated and shouldn't be used in
new driver, this patch removes NETIF_F_LLTX and adds a mmiowb
before sending packet. I have tested this driver on a Eee PC.

The PHY's aneg is configured and restarted whenever the link is brought up,
e.g. when DHCP is started after the kernel has booted.  This can take the
link down for several seconds while auto-negotiation is redone.

If the advertised features haven't changed, then it shouldn't be necessary
to bring down the link and start auto-negotiation over again.

genphy_config_advert() is enhanced to return 0 when the advertised features
haven't been changed and >0 when they have been.

genphy_config_aneg() then uses this information to not call
genphy_restart_aneg() if there has been no change.
