The PCIe max FTS limit is too aggressive on these chips. This patch
loosens the limit a little to eliminate data corruption issues.

This patch consolidates the skb cleanup code into a function named
tg3_skb_error_unmap(). The modification addresses a long-standing bug
where pci_unmap_single() was incorrectly being called instead of
pci_unmap_page() in tigon3_dma_hwbug_workaround().

It has been recently discovered that all tg3 devices have a 4Gb boundary
DMA problem, and that all 5755 and newer devices can't handle fragments
less than or equal to 8 bytes in size. This patch adjusts the flags and
removes tg3_start_xmit(). tg3_start_xmit_dma_bug() has been renamed to
tg3_start_xmit().

tg3 is supposed to enable WoL by default on adapters which support
that, but it fails to do so unless the adapter's
/sys/devices/.../power/wakeup file contains 'enabled' during the
initialization of the adapter. Fix that by making tg3 use
device_set_wakeup_enable() to enable wakeup automatically whenever
WoL should be enabled by default.

This updates the network drivers so that they don't access the
ethtool_cmd::speed field directly, but use ethtool_cmd_speed()
instead.
For most of the drivers, these changes are purely cosmetic and don't
fix any problem, such as for those 1GbE/10GbE drivers that indirectly
call their own ethtool get_settings()/mii_ethtool_gset(). The changes
are meant to enforce code consistency and provide robustness with
future larger throughputs, at the expense of a few CPU cycles for each
ethtool operation.
All drivers compiled with make allyesconfig ion x86_64 have been
updated.
Tested: make allyesconfig on x86_64 + e1000e/bnx2x work

When tg3 was new, phy accesses through ioctl were allowable at any time.
Then, the driver started shutting down the phy when the device was
closed. Phy accesses would be allowed when the driver first attached to
the device, but then would be forbidden after the device had been up'd
and down'd. After that, management firmware made it illegal to access
the phy unless the driver "owned" the device. Now that most firmware
is being moved over to the APE, it is less clear when phy accesses are
safe.
While it is possible to attempt to identify these conditions and code
the driver to navigate through the pitfalls, it could be perplexing to
the admin why phy accesses work in some cases and not others. This
patch brings some uniformity to the problem by only allowing phy
accesses while the driver has control of the device.

The oldest tg3 devices had large rx producer ring BD caches. Back then,
it made sense to make the BD cache replenish threshold only a function
of the number of rx buffers posted by the driver. Since then, the BD
cache sizes have shrunk to 25% of their original size and, in some
cases, the ring sizes have quadrupled in size. Under such conditions,
static BD cache replenish thresholds no longer match the hardware
constraints.
This patch attempts to factor in the BD cache size into the bd cache
replenish strategy, taking the existing hardware bugs into account.

When physical identification of an adapter is done by toggling the
mechanism on and off through software utilizing the set_phys_id operation,
it is done with a fixed duration for both on and off states. Some drivers
may want to set a custom duration for the on/off intervals. This patch
changes the API so the return code from the driver's entry point when it
is called with ETHTOOL_ID_ACTIVE can specify the frequency at which to
cycle the on/off states, and updates the drivers that have already been
converted to use the new set_phys_id and use the synchronous method for
identifying an adapter.
The physical identification frequency set in the updated drivers is based
on how it was done prior to the introduction of set_phys_id.
Compile tested only. Also fixes a compiler warning in sfc.
v2: drivers do not return -EINVAL for ETHOOL_ID_ACTIVE
v3: fold patchset into single patch and cleanup per Ben's feedback

The IRQF_SAMPLE_RANDOM flag is marked as deprecated and will be removed.
Every input point to the kernel's entropy pool have to better document the
type of entropy source it is.
drivers/char/random.c now implements a set of interfaces that can be used for
devices to collect enviromental noise. IRQF_SAMPLE_RANDOM will be replaced
with these add_*_randomness exported functions.
Network drivers are not a good source of entropy. They use as a source of
entropy essentially a remote host. Which means that the source of entropy can
be potentially controlled by an attacker. Also, with heavy workloads the
entropy decreases due to less hardware interrupts happening thanks to irq
mitigation and NAPI.
If a system relies in its network interface as a entropy source it has a false
sense of security. Systems that don't have devices whose drivers are good
sources of entropy, should either use a hardware random number generator or
feed the kernel's entropy pool from userspace using other sources of entropy
such as EGD, video_entropyd, timer_entropyd and audio-entropyd.
