Commit f4a46d1f introduced a bug where
the ifconfig stats would remain 0 for phylib devices. This is due to
tp->link_up flag never becoming true causing tg3_periodic_fetch_stats()
to return.

The link_up flag was being updated in tg3_test_and_report_link_chg()
after setting up the phy. This function however, is not called for
phylib devices since the driver does not do the phy setup.

This patch moves the link_up flag update into the common
tg3_link_report() function that gets called for phylib devices as well
for non phylib devices when the link state changes.

To avoid updating link_up twice, we replace tg3_carrier_...() calls that
are followed by tg3_link_report(), with netif_carrier_...(). We can then
remove the unused tg3_carrier_on() function.

When a KR2 device is connected to a KR link-partner, sometimes it requires
disabling KR2 for the link to come up. To get a KR2 link up later, in case no
base pages are seen, the KR2 is restored. The problem was that some link
partners cleared their advertised BP/NP after around two seconds, causing the
driver to disable/enable KR2 link all the time.
The fix was to wait at least 5 seconds before checking KR2 recovery.

Commit 37706996 "mlx4_en: fix allocation of CPU affinity reverse-map" fixed

introduced a regression.

When the mlx4_core is activating its "legacy mode" (e.g when running in SRIOV
mode) w.r.t to EQs/IRQs usage, comp_pool becomes zero and we're crashing on
divide by zero alloc_cpu_rmap.

Fix that by enabling RFS only when running in non-legacy mode.

The set_param_l function assumes casting a u64 pointer to a u32 pointer
allows to access the lower 32bits, but it results in writing the upper
32 bits on big endian systems.

The fixed function reads the upper 32 bits of the 64 argument, and or's
them with the 32 bits of the 32-bit value passed to the function.

Since this is now a "read-modify-write" operation, we got many
"unintialized variable" warnings which needed to be fixed as well.

This patch removes redundant actions from driver and fixes its interaction
with actions in pci-bus runtime power management code.

It removes pci_save_state() from __e1000_shutdown() for normal adapters,
PCI bus callbacks pci_pm_*() will do all this for us. Now __e1000_shutdown()
switches to D3-state only quad-port adapters, because they needs quirk for
clearing false-positive error from downsteam pci-e port.

pci_save_state() now called after clearing bus-master bit, thus __e1000_resume()
and e1000_io_slot_reset() must set it back after restoring configuration space.

This patch set get_link_status before calling pm_runtime_put() in e1000_open()
to allow e1000_idle() get real link status and schedule first runtime suspend.

This patch also enables wakeup for device if management mode is enabled
(like for WoL) as result pci_prepare_to_sleep() would setup wakeup without
special actions like custom 'enable_wakeup' sign.

This time just passing along a big batch of fixes from Johannes...

For the mac80211 bits:

"Here I have fixes from Ben Greear for stray work items when deleting
interfaces, another idle handling fix from Felix, a fix from Marco ro a
mesh PS buffering crash and I have a fix for the VHT MCS calculation in
association request frames and more nl80211 feature advertising removal
as well as a workaround to increase the dump size if the SKB overhead is
too large. For 3.10 I already have a complete fix queued, but that also
requires (simple) userspace changes."

And for the iwlwifi bits:

"The patches from Dor fix a bunch of calibration issues in the new MVM
driver, and Emmanuel has a number of fixes there as well. Also, we
decided to disable 8k A-MSDU by default, so that's in there. My own
patches are addressing an issue we found with the new devices but that
seems to also exist on older ones, the DMA writeback the devices do can
be delayed and cause issues. The fix is unfortunately relatively large
and depends on two other changes (to not be hugely conflicting), but I
think it's still worth it at this point."

As Johannes says, it is a bit large.  But I hope it is still early
enough in the cycle to make that worthwhile.

====================
Fix regressions introduced by the last set of fixes (sorry):

1. Potential deadlock when disabling TX queues.
2. RX was broken on architectures other than x86 and powerpc.

I still expect to send one more bug fix for 3.9, but as it sometimes
takes days to reproduce the bug it's going to take a couple of weeks of
testing to be confident that it's really fixed.

RX DMA buffers start at an offset of EFX_PAGE_IP_ALIGN bytes from the
start of a cache line.  This offset obviously needs to be included in
the virtual address, but this was missed in commit b590ace0
('sfc: Fix efx_rx_buf_offset() in the presence of swiotlb') since
EFX_PAGE_IP_ALIGN is equal to 0 on both x86 and powerpc.

efx_device_detach_sync() locks all TX queues before marking the device
detached and thus disabling further TX scheduling.  But it can still
be interrupted by TX completions which then result in TX scheduling in
soft interrupt context.  This will deadlock when it tries to acquire
a TX queue lock that efx_device_detach_sync() already acquired.

To avoid deadlock, we must use netif_tx_{,un}lock_bh().

Merge branch 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless into for-davem

While PCI card faces EEH errors, reset (usually hot reset) is
expected to recover from the EEH errors. After EEH core finishes
the reset, the driver callback (be_eeh_reset) is called and wait
the firmware to complete POST successfully. The original code would
return with error once detecting failure during POST stage. That
seems not enough.

The patch forces the driver (be_eeh_reset) to wait the firmware
completes POST until timeout, instead of returning error upon
detection POST failure immediately. Also, it would improve the
reliability of the EEH funtionality of the driver.
