bnx2x_init_bp() allocates memory with bnx2x_alloc_mem_bp() so if we
fail later in bnx2x_init_one() we need to free this memory
with bnx2x_free_mem_bp() to avoid leakages. E.g. I'm observing memory
leaks reported by kmemleak when a failure (unrelated) happens in
bnx2x_vfpf_acquire().

Since NAPI works by shutting down event interrupts when theres
work and turning them on when theres none, the net driver must
make sure that interrupts are disabled when it reschedules polling.
By calling napi_reschedule, the driver switches to polling mode,
therefor there should be no interrupt interference.
Any received packets will be handled in nps_enet_poll by polling the HW
indication of received packet until all packets are handled.

PFs and VFs differ in their registered ethtool operations,
but they're using a common function for get_sset_count().
As a result, `ethtool -i' for a VF would indicate it supports
selftest, although that's not the case.

Since driver is using a FW-based GRO implementation, this has some
effects on its ability to cope with GRO enablement/disablement.
As a result, driver must perform an inner-reload as a result of a state
change in the offload configuration of said feature.
[Failure to do so means network stack would continue to receive
aggregated packets even though user requested the feature to be disabled].

mlx4 uses a private struct net_device_stats in a vain attempt
to avoid races.
This is buggy because multiple cpus could call mlx4_en_get_stats()
at the same time, so ret_stats can not guarantee stable results.
To fix this, we need to switch to ndo_get_stats64() as this
method provides per-thread storage.
This allows to reduce mlx4_en_priv bloat.

1) mlx4_en_xmit() can increment priv->stats.tx_dropped, but this variable
is overwritten in mlx4_en_DUMP_ETH_STATS().
2) This increment was not SMP safe, as a port might have many TX queues.
Add a per TX ring tx_dropped to fix these issues.
This is u32 as mlx4_en_DUMP_ETH_STATS() will add a 32bit field.
So lets avoid bugs with SNMP agents having to cope with partial
overwraps. (One of these agents being bond_fold_stats())

The memcpy() currently copies mdio_bus_data into new_bus->irq, which
makes no sense, since the mdio_bus_data structure contains more than
just irqs. The code was likely supposed to copy mdio_bus_data->irqs
into the new_bus->irq instead, so fix this.

This patch follows Eric Dumazet's commit 7b70176421 for Atheros
atl1c driver to fix one exactly same bug in alx driver, that the
network link will be lost in 1-5 minutes after the device is up.
My laptop Lenovo Y580 with Atheros AR8161 ethernet device hit the
same problem with kernel 4.4, and it will be cured by Jarod Wilson's
commit c406700c for alx driver which get merged in 4.5. But there
are still some alx devices can't function well even with Jarod's
patch, while this patch could make them work fine. More details on
https://bugzilla.kernel.org/show_bug.cgi?id=70761
The debug shows the issue is very likely to be related with the RX
DMA address, specifically 0x...f80, if RX buffer get 0x...f80 several
times, their will be RX overflow error and device will stop working.
For kernel 4.5.0 with Jarod's patch which works fine with my
AR8161/Lennov Y580, if I made some change to the
__netdev_alloc_skb
--> __alloc_page_frag()
to make the allocated buffer can get an address with 0x...f80,
then the same error happens. If I make it to 0x...f40 or 0x....fc0,
everything will be still fine. So I tend to believe that the
0x..f80 address cause the silicon to behave abnormally.

One timer, whose handler keeps reading on MMIO register for EEH
core to detect error in time, is started when the PCI device driver
is loaded. MMIO register can't be accessed during PE reset in EEH
recovery. Otherwise, the unexpected recursive error is triggered.
The timer isn't closed that time if the interface isn't brought
up. So the unexpected recursive error is seen during EEH recovery
when the interface is down.
This avoids the unexpected recursive EEH error by closing the timer
in qlge_io_error_detected() before EEH PE reset unconditionally. The
timer is started unconditionally after EEH PE reset in qlge_io_resume().
Also, the timer should be closed unconditionally when the device is
removed from the system permanently in qlge_io_error_detected().

Most users of IS_ERR_VALUE() in the kernel are wrong, as they
pass an 'int' into a function that takes an 'unsigned long'
argument. This happens to work because the type is sign-extended
on 64-bit architectures before it gets converted into an
unsigned type.
However, anything that passes an 'unsigned short' or 'unsigned int'
argument into IS_ERR_VALUE() is guaranteed to be broken, as are
8-bit integers and types that are wider than 'unsigned long'.
Andrzej Hajda has already fixed a lot of the worst abusers that
were causing actual bugs, but it would be nice to prevent any
users that are not passing 'unsigned long' arguments.
This patch changes all users of IS_ERR_VALUE() that I could find
on 32-bit ARM randconfig builds and x86 allmodconfig. For the
moment, this doesn't change the definition of IS_ERR_VALUE()
because there are probably still architecture specific users
elsewhere.
Almost all the warnings I got are for files that are better off
using 'if (err)' or 'if (err < 0)'.
The only legitimate user I could find that we get a warning for
is the (32-bit only) freescale fman driver, so I did not remove
the IS_ERR_VALUE() there but changed the type to 'unsigned long'.
For 9pfs, I just worked around one user whose calling conventions
are so obscure that I did not dare change the behavior.
I was using this definition for testing:
#define IS_ERR_VALUE(x) ((unsigned long*)NULL == (typeof (x)*)NULL && \
unlikely((unsigned long long)(x) >= (unsigned long long)(typeof(x))-MAX_ERRNO))
which ends up making all 16-bit or wider types work correctly with
the most plausible interpretation of what IS_ERR_VALUE() was supposed
to return according to its users, but also causes a compile-time
warning for any users that do not pass an 'unsigned long' argument.
I suggested this approach earlier this year, but back then we ended
up deciding to just fix the users that are obviously broken. After
the initial warning that caused me to get involved in the discussion
(fs/gfs2/dir.c) showed up again in the mainline kernel, Linus
asked me to send the whole thing again.

This patch defines two new GSO definitions SKB_GSO_IPXIP4 and
SKB_GSO_IPXIP6 along with corresponding NETIF_F_GSO_IPXIP4 and
NETIF_F_GSO_IPXIP6. These are used to described IP in IP
tunnel and what the outer protocol is. The inner protocol
can be deduced from other GSO types (e.g. SKB_GSO_TCPV4 and
SKB_GSO_TCPV6). The GSO types of SKB_GSO_IPIP and SKB_GSO_SIT
are removed (these are both instances of SKB_GSO_IPXIP4).
SKB_GSO_IPXIP6 will be used when support for GSO with IP
encapsulation over IPv6 is added.

Previously, we've fired all our completion callbacks straight from
our ISR.
Some of those callbacks were lightweight (for example, mlx5 Ethernet
napi callbacks), but some of them did more work (for example,
the user-space RDMA stack uverbs' completion handler). Besides that,
doing more than the minimal work in ISR is generally considered wrong,
it could even lead to a hard lockup of the system. Since when a lot
of completion events are generated by the hardware, the loop over
those events could be so long, that we'll get into a hard lockup by
the system watchdog.
In order to avoid that, add a new way of invoking completion events
callbacks. In the interrupt itself, we add the CQs which receive
completion event to a per-EQ list and schedule a tasklet. In the
tasklet context we loop over all the CQs in the list and invoke the
user callback.

The FID value in a ULP_MEMIO command needs to be set to an IQ ID of
a queue configured for our PF. The FID/IQ id is used to index into the
PCIE FID table, to find out on which function the DMA needs to be
issued. Essentially, every DMA needs to have the ingress queue. The exact
ingress queue doesn't matter, but it needs to be an ingress queue
associated with the function you want to see the DMA on.

Many developers already know that field for reference count of the
struct page is _count and atomic type. They would try to handle it
directly and this could break the purpose of page reference count
tracepoint. To prevent direct _count modification, this patch rename it
to _refcount and add warning message on the code. After that, developer
who need to handle reference count will find that field should not be
accessed directly.
