commit e49cc34f introduced an unconditional IRQ_HANDLED return in be_intx()
to workaround Lancer and BE2 HW issues. This is bad as it prevents the kernel
from detecting interrupt storms due to broken HW.
The BE2/Lancer HW issues are:
1) In Lancer, there is no means for the driver to detect if the interrupt
belonged to device, other than counting and notifying events.
2) In Lancer de-asserting INTx takes a while, causing the INTx irq handler
to be called multiple times till the de-assert happens.
3) In BE2, we see an occasional interrupt even when EQs are unarmed.
Issue (1) can cause the notified events to be orphaned, if NAPI was already
running.
This patch fixes this issue by scheduling NAPI only if it is not scheduled
already. Doing this also takes care of possible events_get() race that may be
caused due to issue (2) and (3). Also, IRQ_HANDLED is returned only the first
time zero events are detected.
(Thanks Ben H. for the feedback and suggestions.)

Reference count leaking of both module and sock were found:
- When a detached file were closed, its sock refcnt from device were not
released, solving this by add the sock_put().
- The module were hold or drop unconditionally in TUNSETPERSIST, which means we
if we set the persist flag for N times, we need unset it for another N
times. Solving this by only hold or drop an reference when there's a flag

Michael points out that even after Stefan's fix the TUNSETIFF is still allowed
to create a new tap device. This because we only check tfile->tun but the
tfile->detached were introduced. Fix this by failing early in tun_set_iff() if
the file is detached. After this fix, there's no need to do the check again in
tun_set_iff(), so this patch removes it.

It is werid that qlge driver supports NETIF_F_TSO6 but
not NETIF_F_IPV6_CSUM. This also causes some kernel warning [1]
when VLAN device setups on a qlge interface.
I think the qlge hardware doesn't support NETIF_F_IPV6_CSUM,
so we have to just remove the NETIF_F_TSO6 flag.
After this patch, the TCP/IPv6 traffic becomes normal again,
no kernel warnings any more.
NOTE: I only tested it on 2.6.32 kernel, even if the upstream
kernel could fix this automatically (it is hard to track NETIF*
flags), removing it is also safe.

Microblaze doesn't define NO_IRQ and no IRQ is 0.
Arm still uses NO_IRQ as -1 and there is no option
to connect IRQ to irq 0.
That's why <= 0 is only one option how to find out

As part of the previous driver unload flow, whenever bnx2x is
loaded after the UNDI driver it closes all Rx traffic.
However, this leads to management traffic also being stopped until

Commit 70ac618c07 ("ptp: fixup Kconfig for two PHC drivers.") removed all
dependencies for the blackfin hardware time-stamping Kconfig entry. Hardware
time-stamping is only available on BF518 though. Since the Kconfig entry is
'default y', just updateing your kernel source and running `make defconfig` will
result in the the following build errors:
drivers/net/ethernet/adi/bfin_mac.c:694: error: implicit declaration of function ‘bfin_read_EMAC_PTP_CTL’

This patch adds back the dependency on BF518, and since it does not make sense
to expose this config option when the blackfin MAC driver is not enabled also
restore the dependency on BFIN_MAC.

Multiqueue tun devices support detaching a tun_file from its tun_struct
and re-attaching at a later point in time. This allows users to disable
a specific queue temporarily.
ioctl(TUNSETIFF) allows the user to specify the network interface to
attach by name. This means the user can attempt to attach to interface
"B" after detaching from interface "A".
The driver is not designed to support this so check we are re-attaching
to the right tun_struct. Failure to do so may lead to oops.

Recent versions of udev cause synchronous firmware loading from the
probe routine to fail because the request to user space would time
out. The original fix for b43 (commit 6b6fa58) moved the firmware
load from the probe routine to a work queue, but it still used synchronous
firmware loading. This method is OK when b43 is built as a module;
however, it fails when the driver is compiled into the kernel.
This version changes the code to load the initial firmware file
using request_firmware_nowait(). A completion event is used to
hold the work queue until that file is available. This driver
reads several firmware files - the remainder can be read synchronously.
On some test systems, the async read fails; however, a following synch
read works, thus the async failure falls through to the sync try.

firmware, QCA maintains the device driver.
Currently supported:
- STA: with security
- AP: limited to 1 connected STA, security disabled
- Monitor: due to a hardware/firmware limitation
either control or non-control frames are monitored
Using a STA and AP with this drive, one can assemble
a fully functional BSS. Throughput of 1.2Gbps is achieved
with iperf.
The wil6210 cards have on-board flash memory for the

Sean reported that as of 3.7, his AR9170 device no longer works
because the driver fails during initialization. He noted this
is due to:
"In carl9170/fw.c, ar->hw->wiphy is tagged with
NL80211_IFTYPE_MESH_POINT support if the firmware has Content
after Beacon Queuing. This is both in interface_modes and the
only iface_combinations entry.
If CONFIG_MAC80211_MESH is not set, ieee80211_register_hw
removes NL80211_IFTYPE_MESH_POINT from interface_modes, but
not iface_combinations.
wiphy_register then checks to see if every interface type in
every interface combination is in interface_modes.
NL80211_IFTYPE_MESH_POINT was removed, so you get a WARN_ON
warning and it returns -EINVAL, giving up."
Unfortunately, the iface_combination (types) feature bitmap
in ieee80211_iface_limit is part of a const member in the
ieee80211_iface_combination struct. Hence, the MESH_POINT
feature flag can't be masked by wiphy_register in the
same way as interface_modes in ieee80211_register_hw.
