Don't test for having link and let hardware deal with this situation.

Without this patch I see a machine running an -rt patched Linux 
being stuck in sch_direct_xmit when it looses link while there is 
still a packet to be sent. In this case the fec_enet_start_xmit 
routine returned NETDEV_TX_BUSY which makes the network stack 
reschedule the packet and so sch_direct_xmit calls fec_enet_start_xmit again.
I failed to reproduce a complete hang without -rt, but I think the 
problem exists there, too.

Applied, thanks.

Thanks, I see it as a264b981f2c76e281ef27e7232774bf6c54ec865 in 
net.git (i.e.
https://git.kernel.org/cgit/linux/kernel/git/davem/net.git/commit/?id=
a264b981f2c76e281ef27e7232774bf6c54ec865)

You missed to take the

	Acked-and-tested-by: Fugang Duan [off-list ref]

This is not an official tag recognized by patchwork, he should say:

Acked-by: Fugang Duan <redacted>
Tested-by: Fugang Duan <redacted>

I see Linux kernel trees have many non-official tag such as: Acked-and-tested-by.
Anyway, we must follow the official rules. Thanks, David.
