bf069c9726 ixgbe: fix failing to log fan failures
We weren't logging the 82598AT fan failure if it occurred before (ixgbe_open)
as we hadn't sent up to catch the interrupt that event caused.

This patch checks for this failure in:
ixgbe_probe - So we can log the failure asap. We check right after we
set up the adapter->flags, which is when we know that we have a fan.
ixgbe_up_complete - To catch failures that may have happened between probe
and when we set up the interrupt that would normally detect the fan failure.

To enable all of this we need to initialize the adapter flag with
IXGBE_FLAG_FAN_FAIL_CAPABLE when the NIC contained a fan.

9ce77666da ixgbe: Proposed PARCH PCIE legacy I/O port free intel 10Gb NIC driver
Traditionally Intel based NIC drivers request I/O port even though it
doesn't need that really.

Intel PCIE 10Gb driver (ixgbe) also requests I/O port but it doesn't
need it either.

This is a little inconvenient situation because sometimes we have to
handle those cards on the slots where any I/O space is not attached.

So we made pach which makes ixgbe driver legacy I/O port free.

3044b8d1ff ixgbe: Return PCI_ERS_RESULT_DISCONNECT when bus is disabled
According to the "PCI Error Recovery" document, if after a recovery,
the bus is disabled, the error_detected function should return
PCI_ERS_RESULT_DISCONNECT. Actually ixgbe error_detected function is
always returning PCI_ERS_RESULT_NEED_RESET, even if the bus is in failure.
This patch just check if the bus is disabled and then returns
PCI_ERS_RESULT_DISCONNET.

There were still some references to napi_add/del_all left after the dynamic
vector allocation patch.  This patch removes those references since the
ixgbe_napi_add/del_all calls are no longer needed as the napi struct is

7a921c9362 ixgbe: make q_vectors dynamic to reduce netdev size
Currently the q_vectors are being allocated statically inside of the
adapter struct.  This increases the overall size of the adapter struct when
we can easily allocate the vectors dynamically.  This patch changes that
behavior so that the q_vectors are allocated dynamically and the napi
structures are automatically allocated inside of the q_vectors as needed.

e0ca84105b mv643xx_eth: only unmask RX and TX_END interrupts for available queues
It is not a good idea to blindly unmask the RX and TX_END interrupts
for all eight queues on all mv643xx_eth hardware, since some variations
of the hardware have less than eight transmit/receive queues, and the
RX/TX_END interrupts for the queues they don't have can be in use by
other interrupt sources.

On the platforms that mv643xx_eth is used on, the manual skb->data
alignment logic in mv643xx_eth can be simplified, as the only case we
need to handle is where NET_SKB_PAD is not a multiple of the cache
line size.  If this is the case, the extra padding we need can be
computed at compile time, while if NET_SKB_PAD _is_ a multiple of
the cache line size, the code can be optimised out entirely.
