The way we were setting autoneg via ethtool was inconstant with that
of our other drivers.  It will change the following:

If autoneg is off:
>ethtool -a eth0
Pause parameters for eth0:

Autonegotiate:  off
RX:             off
TX:             off

Before:
>ethtool -A eth0 autoneg on
>ethtool -a eth0
Pause parameters for eth0:

Autonegotiate:  off
RX:             off
TX:             off

Now:
>ethtool -A eth0 autoneg on
>ethtool -a eth0
Pause parameters for eth0:

Autonegotiate:  on
RX:             on
TX:             on

There is a small race between when the tx queues are stopped
and when netif_carrier_off() is called in ixgbe_down.  If the
dev_watchdog() timer fires during this time it is possible for
a false tx timeout to occur.

This patch moves the netif_carrier_off() so that it is called before
the tx queues are stopped preventing the dev_watchdog timer from
detecting false tx timeouts.  The race is seen occosionally when
FCoE or DCB settings are being configured or changed.

Testing note, running ifconfig up/down will not reproduce this
issue because dev_open/dev_close call dev_deactivate() and then
dev_activate().

82598/82599 can support EITR == 0, which allows for the
absolutely lowest latency setting in the hardware.  This disables
writeback batching and anything else that relies upon a delayed
interrupt. This patch enables the feature of "override" when a
user sets rx-usecs to zero, the driver will respect that setting
over using RSC, and automatically disable RSC.  If rx-usecs is
used to set the EITR value to 0, then the driver should disable
LRO (aka RSC) internally until EITR is set to non-zero again.

Prompted by a previous patch submitted by Matthew Garret <mjg@redhat.com>,
further digging into errata documentation reveals the current enabling or
disabling of ASPM L0s and L1 states for certain parts supported by this
driver are incorrect.  82571 and 82572 should always disable L1.  For
standard frames, 82573/82574/82583 can enable L1 but L0s must be disabled,
and for jumbo frames 82573/82574 must disable L1.  This allows for some
parts to enable L1 in certain configurations leading to better power
savings.

Also according to the same errata, Early Receive (ERT) should be disabled
on 82573 when using jumbo frames.

tg3: Fix INTx fallback when MSI fails

MSI setup changes the value of irq_vec in struct tg3 *tp.
This attribute must be taken into account and restored before
we try to do a new request_irq for INTx fallback.

In powerpc, the original code was leading to an EINVAL return within
request_irq, because the driver was trying to use the disabled MSI
virtual irq number instead of tp->pdev->irq.

Old P1020RDB device trees were not specifing tbipa address for
MDIO nodes, which is now causing this kernel oops:

 ...
 eth2: TX BD ring size for Q[6]: 256
 eth2: TX BD ring size for Q[7]: 256
 Unable to handle kernel paging request for data at address 0x00000000
 Faulting instruction address: 0xc0015504
 Oops: Kernel access of bad area, sig: 11 [#1]
 ...
 NIP [c0015504] memcpy+0x3c/0x9c
 LR [c000a9f8] __of_translate_address+0xfc/0x21c
 Call Trace:
 [df839e00] [c000a94c] __of_translate_address+0x50/0x21c (unreliable)
 [df839e50] [c01a33e8] get_gfar_tbipa+0xb0/0xe0
 ...

The old device trees are buggy, though having a dead ethernet is
better than a dead kernel, so fix the issue by using of_iomap().

Also, a somewhat similar issue exist in the probe() routine, though
there the oops is only a possibility. Nonetheless, fix it too.
