0a0b7a5f7a can: add driver for Softing card
This patch adds the driver that creates a platform:softing device
from a pcmcia_device
Note: the Kconfig indicates a dependency on the softing.ko driver,
but this is purely to make configuration intuitive. This driver will
work independent, but no CAN network devices appear until softing.ko is
loaded too.

6a108a14fa kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERT
The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option
is used to configure any non-standard kernel with a much larger scope than
only small devices.

This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes
references to the option throughout the kernel.  A new CONFIG_EMBEDDED
option is added that automatically selects CONFIG_EXPERT when enabled and
can be used in the future to isolate options that should only be
considered for embedded systems (RISC architectures, SLOB, etc).

Calling the option "EXPERT" more accurately represents its intention: only
expert users who understand the impact of the configuration changes they
are making should enable it.

4dce2396b3 enic: Bug Fix: Dont reset ENIC_SET_APPLIED flag on port profile disassociate
enic_get_vf_port returns port profile operation status only if ENIC_SET_APPLIED
flag is set. A recent rework of enic_set_port_profile added code to reset this
flag on disassociate. As a result of which a client calling enic_get_vf_port
to get the status of port profile disassociate will always get a return value
of ENODATA. This patch renames ENIC_SET_APPLIED to more appropriate
ENIC_PORT_REQUEST_APPLIED and reverts back the recent change so that the
flag is set both at associate and disassociate of a port profile.

Resulted from bonding driver registering packet handlers via dev_add_pack and
then trying to call pskb_may_pull. If another packet handler (like for AF_PACKET
sockets) gets called first, the delivered skb will have a user count > 1, which
causes pskb_may_pull to BUG halt when it does its skb_shared check.  Fix this by
calling skb_share_check prior to the may_pull call sites in the bonding driver
to clone the skb when needed.  Tested by myself and the reported successfully.

6a3c869a60 cxgb4: fix reported state of interfaces without link
Currently tools like ip and ifconfig report incorrect state for cxgb4
interfaces that are up but do not have link and do so until first link
establishment.  This is because the initial netif_carrier_off call is
before register_netdev and it needs to be after to be fully effective.
Fix this by moving netif_carrier_off into .ndo_open.

1956cc52e7 ns83820: Avoid bad pointer deref in ns83820_init_one().
In drivers/net/ns83820.c::ns83820_init_one() we dynamically allocate
memory via alloc_etherdev(). We then call PRIV() on the returned storage
which is 'return netdev_priv()'. netdev_priv() takes the pointer it is
passed and adds 'ALIGN(sizeof(struct net_device), NETDEV_ALIGN)' to it and
returns it. Then we test the resulting pointer for NULL, which it is
unlikely to be at this point, and later dereference it. This will go bad
if alloc_etherdev() actually returned NULL.

This patch reworks the code slightly so that we test for a NULL pointer
(and return -ENOMEM) directly after calling alloc_etherdev().

b21a342487 bnx2x: Common init will be executed only once after POR
Common init used to be called by the driver when the first port comes up, mainly to reset and reload external PHY microcode.
However, in case management driver is active on the other port, traffic would halted. So limit the common init to be done only once after POR.

38d59392b2 iwlwifi: fix valid chain reading from EEPROM
When read valid tx/rx chains from EEPROM, there is a bug to use the
tx chain value for both tx and rx, the result of this cause low
receive throughput on 1x2 devices becuase rx will only utilize single
chain instead of two chains

599b13adc2 ath5k: fix locking in tx_complete_poll_work
ath5k_reset must be called with sc->lock.  Since the tx queue
watchdog runs in a workqueue and accesses sc, it's appropriate
to just take the lock over the whole function.

811ea256b3 ath9k_hw: do PA offset calibration only on longcal interval
The power detector adc offset calibration has to be done
on 4 minutes interval (longcal * pa_skip_count). But the commit
"ath9k_hw: fix a noise floor calibration related race condition"
makes the PA calibration executed more frequently beased on
nfcal_pending value. Running PAOffset calibration lesser than
longcal interval doesn't help anything and the worse part is that
it causes NF load timeouts and RX deaf conditions.

In a very noisy environment, where the distance b/w AP & station
is ~10 meter and running a downlink udp traffic with frequent
background scan causes "Timeout while waiting for nf to load:
AR_PHY_AGC_CONTROL=0x40d1a" and moves the chip into deaf state.
This issue was originaly reported in Android platform where
the network-manager application does bgscan more frequently
on AR9271 chips. (AR9285 family usb device).

58c5296991 ath9k_hw: ASPM interoperability fix for AR9380/AR9382
There is an interoperability with AR9382/AR9380 in L1 state with a
few root complexes which can cause a hang. This is fixed by
setting some work around bits on the PCIE PHY. We fix by using
a new ini array to modify these bits when the radio is idle.

51956cd68b vmxnet3: Disable napi in suspend, reenable in resume.
There is a small possibility of a race where the suspend routine gets
called, while a napi callback is still pending and when that comes up,
it enables interrupts which just got disabled in the suspend routine.
This change adds napi disable call in suspend and enable in resume to
avoid race.
