dev->name is unavailable before register_netdev, so use

This reverts commit 7bf6bf4803.
The code has both a short existence and an increasing track of failures
despite some work to amend it for -rc1. It is not just a matter of
reading the eeprom: sometimes the eeprom is read correctly, then the mac
address is not written correctly back into the mac registers.
Some chipsets seem to work reliably but it is not clear at this point if
the code can simply be made to work on a per-chipset basis and post -rc1
is not the place where I want to experiment these things.

net: Enable TSO if supported by at least one device
didn't do what was intended because the netdev_compute_features
function was designed for conjunctions. So what happened was that
it would simply take the TSO status of the last constituent device.
This patch extends it to support both conjunctions and disjunctions
under the new name of netdev_increment_features.
It also adds a new function netdev_fix_features which does the
sanity checking that usually occurs upon registration. This ensures
that the computation doesn't result in an illegal combination
since this checking is absent when the change is initiated via
ethtool.
The two users of netdev_compute_features have been converted.

Commit 147e70e6 ("cxgb3: Use SKB list interfaces instead of home-grown

skb queue is never initialized, and therefore trying to add an skb to
it causes a NULL dereference. With the old code there was no need to
initialize the queues because the l2t_entry structures were zeroed,
and the code used NULL to mean empty.

The sparseirq branch is just preliminary groundwork: no sparse IRQs are
actually implemented by this tree anymore - just the new APIs are added
while keeping the old way intact as well (the new APIs map 1:1 to
irq_desc[]). The 'real' sparse IRQ support will then be a relatively
small patch ontop of this - with a v2.6.29 merge target.

As I've reported, ath9k currently fails utterly when fragmentation
is enabled. This makes ath9k "support" hardware fragmentation by
not supporting fragmentation at all to avoid the double-free issue.
The patch also changes mac80211 to report errors from the driver
operation to userspace.
That hack in ath9k should be removed once the rate control algorithm
it has is fixed, and we can at that time consider removing the hw
fragmentation support entirely since it's not used by any driver.

Broadly speaking the 8168c* share some common code which will
be factored in __rtl_hw_start_8168cp. The 8168b* share some
code too but it will be a bit different.
Any change of behavior should be confined to the currently
unidentified 8168 chipsets. They will not be applied the Tx
performance tweak and will emit a warning instead.

I can not argue strongly for (or against) a specific ordering
on a purely technical ground but the patch avoids to swallow
Realtek's changes in one big, hard-to-read gulp.
Let aside the way the RxConfig register is written (see
rtl_set_rx_tx_config_registers / RxConfig / rtl_set_rx_mode),
this change brings the registers write ordering closer with
Realtek's driver one (version 8.006.00) for the 8168 chipsets.
More 8168 specific code which touches the Configx registers will
be added in the section covered by Cfg9346_UnLock / Cfg9346_Lock.
This code should not be the cause of regression for 810x and
8110 users.

1. arch/powerpc/platforms/pasemi/gpio_mdio.c also needs to be
converted over to mdiobus_{alloc,free}().
2. drivers/net/phy/fixed.c used to embed a struct mii_bus into its
struct fixed_mdio_bus and then use container_of() to go from the
former to the latter. Since mii bus structures are no longer
embedded, we need to do something like use the mii bus private
pointer to go from mii_bus to fixed_mdio_bus instead.

The device's carrier status is controlled via the functions
netif_carrier_on() and netif_carrier_off(). These set or clear a bit
indicating the carrier (aka lower level link) is down, and if the state
changed, they fire off a routing netlink event.
Add a call to netif_carrier_off() before register_netdev() so that the
newly created device will be set to carrier down. Then when the carrier
comes up for the first time, a netlink event will be generated, as the
carrier changed from down to up. Otherwise the initial carrier up will
appear to be changing the status from up to up, and so no event is
generated since that's not a change.

The PHY's aneg is configured and restarted whenever the link is brought up,
e.g. when DHCP is started after the kernel has booted. This can take the
link down for several seconds while auto-negotiation is redone.
If the advertised features haven't changed, then it shouldn't be necessary
to bring down the link and start auto-negotiation over again.
genphy_config_advert() is enhanced to return 0 when the advertised features
haven't been changed and >0 when they have been.
genphy_config_aneg() then uses this information to not call
genphy_restart_aneg() if there has been no change.

Doing 'WARN_ON(preempt_count())' was horribly horribly wrong, and would
cause tons of warnings at bootup if PREEMPT was enabled because the
initcalls currently run with the kernel lock, which increments the
preempt count.
At the same time, the warning was also insufficient, since it didn't
check that interrupts were enabled.
The proper debug function to use for something that can sleep and wants
a warning if it's called in the wrong context is 'might_sleep()'.

The PowerPC 405EZ SoC has some differences in the interrupt layout and
handling for the MAL. The SERR, TXDE, and RXDE interrupts are OR'd into
a single interrupt. Also, due to the possibility for interrupt coalescing,
the TXEOB and RXEOB interrupts require an interrupt bit to be cleared in
the ICINTSTAT SDR.
This sets the proper MAL feature bits for 405EZ boards, and adds a common
shared handler for SERR, TXDE, and RXDE. The defines for the ICINTSTAT DCR
are added to the proper header file as well.
This has been adapted from code originally written by Stefan Roese.

There are some PowerPC SoCs that do odd things with the MAL handling. In
order to accommodate them, we need to introduce a feature mechanism that is
similar to the existing emac_has_feature function.
This adds a feature variable to the mal_instance structure, and adds a
mal_has_feature function. Two features are defined and are guarded
by Kconfig options that are selected by the affected platforms.
MAL_FTR_CLEAR_ICINSTAT is used for platforms that need to clear the
interrupt bits in the ICINTSTAT SDR for txeob/rxeob. This is common
on MAL implementations that have interrupt coalescing.
MAL_FTR_COMMON_ERR_INT is used for platforms that have SERR, TXDE,
and RXDE OR'd into a single interrupt bit.

0000:01:00.0: eth0: (PCI Express:2.5GB/s:Width x1) 00:16:76:04:ff:09
The second seems correct, but the first has a silly repetition of the
PCI device before the actual message. The message originates from
e1000_eeprom_checks in e1000e/netdev.c.
With this patch below the first message becomes
e1000e 0000:01:00.0: Warning: detected DSPD enabled in EEPROM
which makes it similar to directly preceding messages.
Use dev_warn instead of e_warn in e1000_eeprom_checks() as the interface

Removing the module would cause a kernel oops as platform_driver_probe
failed to detect a device and unregistered the platform driver on module
init, and cleanup_module would unregister the already unregistered driver.
The suspend and resume functions weren't being called.
platform_driver support was added earlier, but without any
platform_device_register* calls I don't think it was being used. Now all
devices are registered using platform_device_register_simple and pointers
are kept to unregister the ones that the probe failed for or unregister
all devices on module shutdown. init_module no longer calls ne_init to
reduce confusion (and multiple unregister paths that caused the rmmod
oops). With the devices now registered they are added to the platform
driver and get suspend and resume events.
netif_device_detach(dev) was added before unregister_netdev(dev) when
removing the region as occationally I would see a race condition where the
device was still being used in unregister_netdev.

The loop with the timeout used "while (... && timeout--)", which means
than when the timeout occurs, "timeout" will be -1 after the loop has
exited. The code that checks if the looped exited because of a timeout
used "if (timeout <= 0)". Seems ok, except timeout is unsigned, and
(unsigned)-1 isn't less than zero!
Using "--timeout" in the loop fixes this problem, as now "timeout" will be
0 when the loop times out.
This also fixes a bug in the existing code, where it will erroneously think
a timeout occurred if the condition the loop was waiting for is satisfied
on the final iteration before a timeout.

This is a massive update that includes infrastructure for further patches
where we will add support for more phy types and eeprom types.
This code is shared as much as possible with other drivers, so the code may
seem a little obtuse at times but wherever possible we keep to the linux
style and methods.

in some configurations there can be more than one rx queue per vector
in msi-x mode. Add functionality to be able to clean this without
changing the performance path single-rx-queue cleanup.

changing ring sizes in ethtool needs to be robust. If an allocation fails the
driver must continue operation, with the previous settings.

most of the time we only need 1500 bytes for a packet which means
we don't need a whole 4k page for each packet. Share the allocation
by using a reference count to the page and giving half to two
receive descriptors. This can enable us to use packet split mode
all the time due to the performance increase of allocating half
the pages.
