net: use helpers to access mc list V2
This patch introduces the similar helpers as those already done for uc list.
However multicast lists are no list_head lists but "mademanually". The three
macros added by this patch will make the transition of mc_list to list_head
smooth in two steps:
1) convert all drivers to use these macros (with the original iterator of type
"struct dev_mc_list")
2) once all drivers are converted, convert list type and iterators to "struct
netdev_hw_addr" in one patch.
>From now on, drivers can (and should) use "netdev_for_each_mc_addr" to iterate
over the addresses with iterator of type "struct netdev_hw_addr". Also macros
"netdev_mc_count" and "netdev_mc_empty" to read list's length. This is the state
which should be reached in all drivers.

This patch addresses concerns about efficiency of handling incoming

which has a smaller latency than workqueues. This change needed a rework
of the locking scheme that was much simplified. Some other (more or less
longstanding) bugs are fixed: utilization of just half of the RX
buffers, useless wait for interrupt on open, more reliable reset
sequence. The MERR interrupt is not used anymore: it overloads the CPU
in error-passive state without any additional information. One shot mode

In order to use macvlan with qemu and other tools that require

Macvtap interfaces are created in the same way as macvlan
interfaces using ip link, but the netif is just used as a
handle for configuration and accounting, while the data
goes through the chardev. Each macvtap interface has its
own character device, simplifying permission management
significantly over the generic tun/tap driver.

- Adlink PCI-7841/cPCI-7841 card (http://www.adlinktech.com/)
- Adlink PCI-7841/cPCI-7841 SE card
- Marathon CAN-bus-PCI card (http://www.marathon.ru/)
- TEWS TECHNOLOGIES TPMC810 card (http://www.tews.com/)
Changes since v1:
- Added some defines for static inline int plx_pci_check_sja1000(...)
- static struct pci_device_id plx_pci_tbl[] replaced by
static DEFINE_PCI_DEVICE_TABLE(plx_pci_tbl)
- Typo fixed

MCS7830 USB-Ether: resume _with_ working link, via .reset_resume support
ChangeLog:
Implement .reset_resume support to retain a live network connection
during suspend despite USB power loss.
- rework operation to reference cached data in mcs7830_data and
netdev->dev_addr
- update netdev->dev_addr only in case new MAC was set successfully
. Tests done:
. ethtool -d pre-/post-suspend: register values match
. running ssh session suspend, resume: works
. ifdown device, suspend, resume: works
. ifup, suspend, unplug, resume: WORKS (eth1 is removed, re-ifup of eth1

netlink: fix for too early rmmod
Netlink code does module autoload if protocol userspace is asking for is

netlink_create() in such situation _will_ create userspace socket and

af_key: fix netns ops ordering on module load/unload
1. After sock_register() returns, it's possible to create sockets,
even if module still not initialized fully (blame generic module code

2. Consequently, pfkey_create() can be called with pfkey_net_id still not
initialized which will BUG_ON in net_generic():
kernel BUG at include/net/netns/generic.h:43!
3. During netns shutdown, netns ops should be unregistered after
key manager unregistered because key manager calls can be triggered

Getting it is not used, let's drop support for notifications about
(un)registered events from connector.
Another option was to check credentials on receiving, but we can always
restore it without bugs if needed, but genetlink has a wider code base
and none complained, that userspace can not get notification when some
other clients were (un)registered.
Kudos for Sebastian Krahmer <krahmer@suse.de>, who found a bug in the
code.

mac80211: fix sta lookup with AP VLAN interfaces and injected frames
When injecting frames, mac80211 currently looks for the first AP
interface that matches the source address of the injected frame.
This breaks when such a frame is directed at a STA that has been moved
to a VLAN. This patch fixes it by using sta_info_get_bss instead of
sta_info_get, which also finds stations belonging to a VLAN interface
of the same BSS as the AP interface.

mac80211: fix monitor mode tx radiotap header handling
When an injected frame gets buffered for a powersave STA or filtered
and retransmitted, mac80211 attempts to parse the radiotap header
again, which doesn't work because it's gone at that point.
This patch adds a new flag for checking the availability of a radiotap
header, so that it only attempts to parse it once, reusing the tx info
on the next call to ieee80211_tx().
This fixes severe issues with rekeying in AP mode.

mac80211: fix sta lookup for received action frames on an AP VLAN
When looking for a matching interface, __ieee80211_rx_handle_packet
loops over all active interfaces, looking for matching stations.
Because AP VLAN interfaces are not processed as part of this loop, it
needs to use sta_info_get_bss instead of sta_info_get in order to find
a STA that has been moved to a VLAN.
This fixes issues with aggregation setup/teardown.

The maximal size of the "ht_capa" file is 430 bytes. In most cases,
it's much shorter. Use a 512 byte long buffer. 1024 bytes is too much
and causes a warning with CONFIG_FRAME_WARN=1024.

cfg80211: add regulatory hint disconnect support
This adds a new regulatory hint to be used when we know all
devices have been disconnected and idle. This can happen
when we suspend, for instance. When we disconnect we can
no longer assume the same regulatory rules learned from
a country IE or beacon hints are applicable so restore
regulatory settings to an initial state.
Since driver hints are cached on the wiphy that called
the hint, those hints are not reproduced onto cfg80211
as the wiphy will respect its own wiphy->regd regardless.

cfg80211: avoid flushing the global workqueue for core reg hints
When cfg80211 starts it will send a core regulatory hint. This is
sent to the global workqueue but we force processing of it by
flushing the global workqueue. The flushing was done since
cfg80211 needs last_request to always be populated.
Avoid flushing the global workqueue by processing the work
required immediately instead of putting it into a linked
list and processing it after the flush.
