Commit 2e30168b ("libertas: terminate scan when stopping interface")
adds cleanup code to lbs_eth_stop to call cfg80211_scan_done if there's
an outstanding cfg80211_scan_request. However, it assumes that the
scan request was allocated via the cfg80211 stack. Libertas has
its own internal allocation method, kept track of with
priv->internal_scan. This doesn't set scan_req->wiphy, amongst other
things, which results in hitting a BUG() when we call cfg80211_scan_done
on the request.
This provides a function to take care of the low-level scan_req cleanup
details. We simply call that to deal with finishing up scan requests.
The bug we were hitting was:

This patch resolves two sets of race conditions.
Mitsuo Hayasaka <mitsuo.hayasaka.hu@hitachi.com> reported the
first, as follows:
The bond_close() calls cancel_delayed_work() to cancel delayed works.
It, however, cannot cancel works that were already queued in workqueue.
The bond_open() initializes work->data, and proccess_one_work() refers
get_work_cwq(work)->wq->flags. The get_work_cwq() returns NULL when
work->data has been initialized. Thus, a panic occurs.
He included a patch that converted the cancel_delayed_work calls
in bond_close to flush_delayed_work_sync, which eliminated the above
problem.
His patch is incorporated, at least in principle, into this
patch. In this patch, we use cancel_delayed_work_sync in place of
flush_delayed_work_sync, and also convert bond_uninit in addition to
bond_close.
This conversion to _sync, however, opens new races between
bond_close and three periodically executing workqueue functions:
bond_mii_monitor, bond_alb_monitor and bond_activebackup_arp_mon.
The race occurs because bond_close and bond_uninit are always
called with RTNL held, and these workqueue functions may acquire RTNL to
perform failover-related activities. If bond_close or bond_uninit is
waiting in cancel_delayed_work_sync, deadlock occurs.
These deadlocks are resolved by having the workqueue functions
acquire RTNL conditionally. If the rtnl_trylock() fails, the functions
reschedule and return immediately. For the cases that are attempting to
perform link failover, a delay of 1 is used; for the other cases, the
normal interval is used (as those activities are not as time critical).
Additionally, the bond_mii_monitor function now stores the delay
in a variable (mimicing the structure of activebackup_arp_mon).
Lastly, all of the above renders the kill_timers sentinel moot,
and therefore it has been removed.

This patch updates the normal descriptor structure
to work fine on new GMAC Synopsys chips.
Normal descriptors were designed on the old MAC10/100
databook 1.91 where some bits were reserved: for example
the tx checksum insertion and rx checksum offload.
The patch maintains the back-compatibility with old
MAC devices (tested on STx7109 MAC10/100) and adds new
fields that actually new GMAC devices can use.
For example, STx7109 (MAC10/100) will pass from the platform
tx_coe = 0, enh_desc = 0, has_gmac = 0.
A platform like Loongson1B (GMAC) will pass:
tx_coe = 1, enh_desc = 0, has_gmac = 1.
Thanks to Kelvin, he enhanced the normal descriptors for
GMAC (on MIPS Loongson1B platform).

Currently the code for VF setup/teardown done by a PF (if_create,
mac_add_config, link_status_query etc) is scattered; this patch
refactors this code into be_vf_setup() and be_vf_clear(). The
if_create/if_destroy/mac_addr_query cmds are now called after the MCCQ
is created; so these cmds are now modified to use the MCCQ instead of
MBOX.

When a card is reset due to EEH error recovery or due to a suspend,
rx-mode config (promisc/mc) is not being sent to the FW. be_setup() is
called in these flows and is the best place for such config/re-config
cmds. Hence include rx-mode, vlan and flow-control config in
be_setup().

there are two platform drivers named "mdio-gpio" registered.
I renamed the of variant to "mdio-ofgpio".

If the device is down during suspend/resume, interrupts are enabled
without a registered interrupt handler, causing a storm of
unhandled interrupts until the IRQ is disabled because "nobody
cared".
Instead, check that the device is up before touching it in the
suspend/resume code.

Ari got kernel panics using tg3 NIC, and bisected to 2669069aac "tg3:
enable transmit time stamping."
This is because tigon3_dma_hwbug_workaround() might alloc a new skb and
free the original. We panic when skb_tx_timestamp() is called on freed
skb.

Due to a hardware problem, writes to the VFTA register can
theoretically fail. Although the likelihood of this is very low.
This patch adds a shadow vfta in the adapter struct for reading
and adds new write functions for these devices to work around the problem.

In 82580 and later devices, the alternate MAC address feature is
completely handled by the option ROM and software does not handle
it anymore. This patch changes the check_alt_mac_addr function to
exit immediately if device is 82580 or later.

On systems that create and delete lots of dynamic devices the
31bit linux ifindex fails to fit in the 16bit macvtap minor,
resulting in unusable macvtap devices. I have systems running
automated tests that that hit this condition in just a few days.
Use a linux idr allocator to track which mavtap minor numbers
are available and and to track the association between macvtap
minor numbers and macvtap network devices.
Remove the unnecessary unneccessary check to see if the network
device we have found is indeed a macvtap device. With macvtap
specific data structures it is impossible to find any other
kind of networking device.
Increase the macvtap minor range from 65536 to the full 20 bits
that is supported by linux device numbers. It doesn't solve the
original problem but there is no penalty for a larger minor
device range.

Place macvlan_common_newlink at the end of macvtap_newlink because
failing in newlink after registering your network device is not
supported.
Move device_create into a netdevice creation notifier. The network device
notifier is the only hook that is called after the network device has been
registered with the device layer and before register_network_device returns
success.

To see if it is appropriate to enable the macvtap zero copy feature
don't test the lowerdev network device flags. Instead test the
macvtap network device flags which are a direct copy of the lowerdev
flags. This is important because nothing holds a reference to lowerdev
and on a very bad day we lowerdev could be a pointer to stale memory.
