Use napi_complete_done() instead of __napi_complete() to :
1) Get support of gro_flush_timeout if opt-in
2) Not rearm interrupts for busy-polling users.
3) use standard NAPI API and get rid of napi_gro_flush()

The ethtool api {get|set}_settings is deprecated.
We move this driver to new api {get|set}_link_ksettings.
The callback set_link_ksettings no longer update the value
of advertising, as the struct ethtool_link_ksettings is
defined as const.
As I don't have the hardware, I'd be very pleased if
someone may test this patch.

with leds namespace
Adding led support for phy causes namespace conflicts for some
phy drivers.
The marvel skge driver declared an enum for representing the states of
Link LED Register. The enum contained constant LED_OFF which conflicted
with declartation found in linux/leds.h.
LED_OFF changed to LED_REG_OFF
Also changed LED_ON to LED_REG_ON to avoid possible future conflict and
for consistency.

In my patch c194992cbe71c20bb3623a566af8d11b0bfaa721 ("skge: fix
broken driver") I didn't fix the skge bug correctly. The value of the
new mapping (not old) was passed to pci_unmap_single.
If we enable CONFIG_DMA_API_DEBUG, it results in this warning:
WARNING: CPU: 0 PID: 0 at lib/dma-debug.c:986 check_sync+0x4c4/0x580()
skge 0000:02:07.0: DMA-API: device driver tries to sync DMA memory it has
not allocated [device address=0x000000023a0096c0] [size=1536 bytes]
This patch makes the skge driver pass the correct value to
pci_unmap_single and fixes the warning. It copies the old descriptor to
on-stack variable "ee" and unmaps it if mapping of the new descriptor
succeeded.
This patch should be backported to 3.11-stable.

The patch 136d8f377e1575463b47840bc5f1b22d94bf8f63 broke the skge driver.
Note this part of the patch:
+ if (skge_rx_setup(skge, e, nskb, skge->rx_buf_size) < 0) {
+ dev_kfree_skb(nskb);
+ goto resubmit;
+ }
+
pci_unmap_single(skge->hw->pdev,
dma_unmap_addr(e, mapaddr),
dma_unmap_len(e, maplen),
PCI_DMA_FROMDEVICE);
skb = e->skb;
prefetch(skb->data);
- skge_rx_setup(skge, e, nskb, skge->rx_buf_size);
The function skge_rx_setup modifies e->skb to point to the new skb. Thus,
after this change, the new buffer, not the old, is returned to the
networking stack.
This bug is present in kernels 3.11, 3.11.1 and 3.12-rc1. The patch should
be queued for 3.11-stable.

tasklet_disable will inc tasklet->count and return. If the tasklet
is not handled yet because some softirq pressure, the tasklet will
placed on the tasklet_vec, never have a chance to excute. This might
lead to ksoftirqd heavy loaded, wakeup with pending_softirq, but
tasklet is disabled. tasklet_kill should be used in this case.

Current GRO can hold packets in gro_list for almost unlimited
time, in case napi->poll() handler consumes its budget over and over.
In this case, napi_complete()/napi_gro_flush() are not called.
Another problem is that gro_list is flushed in non friendly way :
We scan the list and complete packets in the reverse order.
(youngest packets first, oldest packets last)
This defeats priorities that sender could have cooked.
Since GRO currently only store TCP packets, we dont really notice the
bug because of retransmits, but this behavior can add unexpected
latencies, particularly on mice flows clamped by elephant flows.
This patch makes sure no packet can stay more than 1 ms in queue, and
only in stress situations.
It also complete packets in the right order to minimize latencies.

Marvell 88E8001 on an ASUS P5NSLI motherboard is unable to send/receive
packets on a system with >4gb ram unless a 32bit DMA mask is used.
This issue has been around for years and a fix was sent 3.5 years ago, but
there was some debate as to whether it should instead be fixed as a PCI quirk.
http://www.spinics.net/lists/netdev/msg88670.html
However, 18 months later a similar workaround was introduced for another
chipset exhibiting the same problem.

The function skge_probe() return 0 for success and negative value
for most of its internal tests failures. There is one exception
that is error case going to err_out_led_off:. For this error case, the
function abort its success execution path, but returns non negative
value, making it difficult for a caller function to notice the error.
This patch fixes the error case that do not return negative value.
This was found by Coccinelle, but the code change was made by hand.
This patch is not robot generated.
A simplified version of the semantic match that finds this problem is
as follows: (http://coccinelle.lip6.fr/)
// <smpl>

Most boards with SysKonnect/Marvell Ethernet have only a single port.
For the single port case, use the standard Ethernet driver convention
of allocating IRQ when device is brought up rather than at probe time.
This patch also adds some additional read after writes to avoid any
PCI posting problems when setting the IRQ mask.
The error handling of dual port cards is also changed. If second port
can not be brought up, then just fail. No point in continuing, since
the failure is most certainly because of out of memory.
It is worth noting that the dual port skge device has a single irq but two
seperate status rings and therefore has two NAPI objects, one for
each port.
