Introduce a bnx2_napi structure that will hold a napi_struct and
other fields to handle NAPI polling for the napi_struct. Various tx
and rx indexes and status block pointers will be moved from the main
bnx2 structure to this bnx2_napi structure.
Most NAPI path functions are modified to be passed this bnx2_napi
struct pointer.

smc91x is shared between many different platforms. Each platform needs
to specify the interrupt type, and in some cases the irq type depends
on more than just the build configuration - it depends on runtime
checks.
Rather than throwing this code into the SMC_IRQ_FLAGS definition, provide
a way for these flags to be passed via the IRQ resource itself.
Note that IRQF_TRIGGER_* constants are intentionally defined to correspond
with the IORESOURCE_IRQ_* interrupt type flags, in much the same way that
the low bits of PCI iomem resources correspond with the BAR flag bits.
Also provide a way to configure smc91x to read the IRQ flags from the
resource. Once all platforms have been converted over (signified
by all definitions of SMC_IRQ_FLAGS being -1) SMC_IRQ_FLAGS should
be removed.

When unregistering the rtnl_link_ops, all existing devices using
the ops are destroyed. With nested devices this may lead to a
use-after-free despite the use of for_each_netdev_safe() in case
the upper device is next in the device list and is destroyed
by the NETDEV_UNREGISTER notifier.
The easy fix is to restart scanning the device list after removing
a device. Alternatively we could add new devices to the front of
the list to avoid having dependant devices follow the device they
depend on. A third option would be to only restart scanning if
dev->iflink of the next device matches dev->ifindex of the current
one. For now this seems like the safest solution.
With this patch, the veth rtnl_link_ops unregistration can use
rtnl_link_unregister() directly since it now also handles destruction
of multiple devices at once.

Several of the Intel ethernet drivers keep an atomic counter used to
manage when to actually hit the hardware with a disable or an enable.
The way the net_rx_work() breakout logic works during a pending
napi_disable() is that it simply unschedules the poll even if it
still has work.
This can potentially leave interrupts disabled, but that is OK
because all of the drivers are about to disable interrupts
anyways in all such code paths that do a napi_disable().
Unfortunately, this trips up the semaphore used here in the Intel
drivers. If you hit this case, when you try to bring the interface
back up it won't enable interrupts. A reload of the driver module
fixes it of course.
So what we do is make sure all the sequences now go:
napi_disable();
atomic_set(&adapter->irq_sem, 0);
*_irq_disable();
which makes sure the counter is always in the correct state.

For cards that initially have the MAC address stored in reverse order,
the forcedeth driver uses a flag to signal whether the address was
already corrected, so that it is not reversed again on a subsequent
probe.
Unfortunately this flag, which is stored in a register of the card,
seems to get lost during suspend, resulting in the MAC address being
reversed again. To fix that, the MAC address needs to be written back
in reversed order before we suspend and the flag needs to be reset.
The flag is still required because at least kexec will never write
back the reversed address and thus needs to know what state the card
is in.

This makes the ->poll() routines of the E100, E1000, E1000E, IXGB, and
IXGBE drivers complete ->poll() consistently.
Now they will all break out when the amount of RX work done is less
than 'budget'.
At a later time, we may want put back code to include the TX work as
well (as at least one other NAPI driver does, but by in large NAPI
drivers do not do this). But if so, it should be done consistently
across the board to all of these drivers.

When we add the generic napi_disable_pending() breakout
logic to net_rx_action() it means that napi_disable()
can cause NAPI poll interrupt events to be disabled.
And this is exactly what we want. If a napi_disable()
is pending, and we are looping in the ->poll(), we want
->poll() event interrupts to stay disabled and we want
to complete the NAPI poll ASAP.
When ->poll() break out during device down was being handled on a
per-driver basis, often these drivers would turn interrupts back on
when '!netif_running()' was detected.
And this would just cause a reschedule of the NAPI ->poll() in the
interrupt handler before the napi_disable() could get in there and
grab the NAPI_STATE_SCHED bit.
The vast majority of drivers don't care if napi_disable() might have
the side effect of disabling NAPI ->poll() event interrupts. In all
such cases, when a napi_disable() is performed, the driver just
disabled interrupts or is about to.
However there were three exceptions to this in PCNET32, R8169, and
SKY2. To fix those cases, at the subsequent napi_enable() points, I
added code to ensure that the ->poll() interrupt events are enabled in
the hardware.

It is possible for the TX ring to have packets sit in it for unbounded
amounts of time.
The only way to defer TX interrupts in the chip is to periodically set
"mark" bits, when processing of a TX descriptor with the mark bit set
is complete it triggers the interrupt for the TX queue's LDG.
A consequence of this kind of scheme is that if packet flow suddenly
stops, the remaining TX packets will just sit there.
If this happens, since those packets could be charged to TCP socket
send queues, such sockets could get stuck.
The simplest solution is to divorce the socket ownership of the packet
once the device takes the SKB, by using skb_orphan() in
niu_start_xmit().
In hindsight, it would have been much nicer if the chip provided two
interrupt sources for TX (like basically every other ethernet chip
does). Namely, keep the "mark" bit, but also signal the LDG when the
TX queue becomes completely empty. That way there is no need to have
a deadlock breaker like this.

niu_slowpath_interrupt() expects values to be setup in lp->{v0,v1,v2}
but they aren't. That's only done by niu_schedule_napi() which is
done later in the interrupt path.
If niu_rx_error() returns zero, and v0 is clear, hit the
RX_DMA_CTL_STATE register with a RX_DMA_CTL_STAT_MEX.
Only emit verbose RX error logs if a fatal channel or port error is
signalled. Other cases will be recorded into statistics by

Here's proposed fix for RX checksum handling in cassini; it affects
little-endian working with half-duplex gigabit, but obviously needs
testing on big-endian too.
The problem is, we need to convert checksum to fixed-endian *before*
correcting for (unstripped) FCS. On big-endian it won't matter
(conversion is no-op), on little-endian it will, but only if FCS is
not stripped by hardware; i.e. in half-duplex gigabit mode when
->crc_size is set.
cassini.c part is that fix, cassini.h one consists of trivial
endianness annotations. With that applied the sucker is endian-clean,
according to sparse.

tg3_nvram_write_block_unbuffered() is reading data from nvram into
allocated buffer before overwriting a part of it with user-supplied
data. Then it feeds the entire page back to nvram. It should be
storing the words it had read as little-endian, not as host-endian.
Note that tg3_set_eeprom() does exactly that for padding the same
data to full words before it gets passed down to tg3_nvram_write_block()
and then to tg3_nvram_write_block_unbuffered().
Moreover, when we get to sending the entire thing back to nvram, we
go through it word-by-word, doing essentially
writel(swab32(le32_to_cpu(word)), ...)
so if we want them to reach the card in host-independent endianness,
we'd better really have all that buffer filled with fixed-endian.
For user-supplied part we obviously do have that (it's an array of
octets memcpy'd in), ditto for padding of user-supplied part to word
boundaries (taken care of in tg3_set_eeprom()). The rest of the
buffer gets filled by tg3_nvram_write_block_unbuffered() and it would
damn better be consistent with that (and with tg3_get_eeprom(), while
we are at it - there we also convert the words read from nvram to
little-endian before returning the buffer to user).
The bug should get triggered on big-endian boxen when set_eeprom is done
for less than entire page. Then the words that should've been unaffected
at all will actually get byteswapped in place in nvram.

Since addition of the rfkill callback, the LED associated with the off

(1) Essential data in the rfkill structure were missing.
(2) The rfkill structure was initialized after the LED initialization.
(3) There was a minor memory leak if the radio LED structure was inited.
Once the above problems were fixed, additional difficulties were noted:
(4) The radio LED was in the wrong state at startup.
(5) The radio switch had to be manipulated twice for each state change.
(6) A circular mutex locking situation existed.
(7) If rfkill-input is built as a module, it is not automatically loaded.

become stuck during testing with high traffic. One port of the 88E8062
would lockup, while the other port remained functional. Re-inserting
the sky2 module would not fix the problem - only a power cycle would.
I looked over Marvell's most recent sk98lin driver and it looks like
they had a "workaround" for the Yukon XL that the sky2 doesn't have yet.
The sk98lin driver disables the RX MAC FIFO flush feature for all
revisions of the Yukon XL.
According to skgeinit.c of the sk98lin driver, "Flushing must be enabled
(needed for ASF see dev. #4.29), but the flushing mask should be
disabled (see dev. #4.115)". Nice. I implemented this same change in
the sky2 driver and verified that the RX lockup I was seeing was
resolved.

Packets can be left in the RX ring if the NAPI budget is reached.
This is caused by storing the latest rx index at the beginning of
bnx2_rx_int(). We may not process all the work up to this index
if the budget is reached and so some packets in the RX ring may rot
when we later check for more work using this stored rx index.
The fix is to not store this latest hw index and only store the
processed rx index. We use a new function bnx2_get_hw_rx_cons()
to fetch the latest hw rx index.

Depending on how the 44x processors are wired, some EMAC cells
might not be useable (and not connected to a PHY). However, some
device-trees may choose to still expose them (since their registers
are present in the MMIO space) but with an "unused" property in them.

With some PHYs, when the link goes away, the EMAC reset fails due
to the loss of the RX clock I believe.
The old EMAC driver worked around that using some internal chip-specific
clock force bits that are different on various 44x implementations.
This is an attempt at doing it differently, by avoiding the reset when
there is no link, but forcing loopback mode instead. It seems to work
on my Taishan 440GX based board so far.

Add new hash for balance-xor and 802.3ad modes. Originally
submitted by "Glenn Griffin" <ggriffin.kernel@gmail.com>; modified by
Jay Vosburgh to move setting of hash policy out of line, tweak the
documentation update and add version update to 3.2.2.
Glenn's original comment follows:
Included is a patch for a new xmit_hash_policy for the bonding driver
that selects slaves based on MAC and IP information. This is a middle
ground between what currently exists in the layer2 only policy and the
layer3+4 policy. This policy strives to be fully 802.3ad compliant by
transmitting every packet of any particular flow over the same link.
As documented the layer3+4 policy is not fully compliant for extreme
cases such as ip fragmentation, so this policy is a nice compromise
for environments that require full compliance but desire more than the
layer2 only policy.
