Juuso Oikarinen 8bf29b0eb3 wl1271: Fix ad-hoc SSID update
If re-configuring the SSID while ad-hoc was already enabled, the beacon
template would be properly updated, but the SSID passed in the CMD_JOIN would
not - hence filtering etc would not work properly.

Juuso Oikarinen ee444cf050 wl1271: Fix WEP key handling

Juuso Oikarinen 6c71b0ea76 wl1271: Optimized RX path packet retrieval
Instead of acking RX packets read from the FW once all (of several possible)
buffered packets are retrieved, ack packets one by one as they are read. This
enables the FW to start receiving more packets from the network while the
host read operation is still ongoing.

Juuso Oikarinen d8c42c0c28 wl1271: Fix PSM entry
Currently the PSM entry function assumes successful operation, and enables
ELP, BET and beacon filtering right away. This is bad, because the PSM
entry may fail due to environmental issues, which will cause the ELP, BET and
beacon filtering to be illegally enabled (because FW remains in active state.)

Fix this by enabling ELP, BET and beacon filtering only after successful entry,
and by ensuring the firmware is in active mode after the failure.

Kalle Valo ffb9eb3d8b nl80211: add power save commands
The most needed command from nl80211, which Wireless Extensions had,
is support for power save mode. Add a simple command to make it possible
to enable and disable power save via nl80211.

I was also planning about extending the interface, for example adding the
timeout value, but after thinking more about this I decided not to do it.
Basically there were three reasons:

Firstly, the parameters for power save are very much hardware dependent.
Trying to find a unified interface which would work with all hardware, and
still make sense to users, will be very difficult.

Secondly, IEEE 802.11 power save implementation in Linux is still in state
of flux. We have a long way to still to go and there is no way to predict
what kind of implementation we will have after few years. And because we
need to support nl80211 interface a long time, practically forever, adding
now parameters to nl80211 might create maintenance problems later on.

Third issue are the users. Power save parameters are mostly used for
debugging, so debugfs is better, more flexible, interface for this.
For example, wpa_supplicant currently doesn't configure anything related
to power save mode. It's better to strive that kernel can automatically
optimise the power save parameters, like with help of pm qos network
and other traffic parameters.

Later on, when we have better understanding of power save, we can extend
this command with more features, if there's a need for that.

Pavel Roskin fbc87d67af Introduce PCMCIA_DEVICE_PROD_ID3
...and use it in hostap_cs and orinoco_cs.

Another PCMCIA device with Intersil Prism chipset has been reported:

Socket 0:
  product info: "Gigabyte", "GN-WLM01_P25L_ADAPTER", "ISL37300P", "Eval-RevA"
  manfid: 0x02e0, 0x1011
  function: 6 (network)

As it's the case with some other Prism based devices, the third ID
string contains a design name that should be sufficient to identify the
card as having Intersil Prism chipset and thus compatible with both
orinoco_cs and hostap_cs.

Introduce PCMCIA_DEVICE_PROD_ID3 that matches the third ID string only.

Use it in orinoco_cs and hostap_cs to match cards with the third ID
string indicating Prism chipset.  Remove corresponding entries that use
PCMCIA_DEVICE_PROD_ID123.

Dan Halperin 5e2f75b899 iwlwifi: set HT flags after channel in rxon
The HT extension channel settings require priv->staging_rxon.channel to be
accurate. However, iwl_set_rxon_ht was being called before iwl_set_rxon_channel
and thus HT40 could be broken unless another call to iwl_mac_config came in.

This problem was recently introduced by "iwlwifi: Fix to set correct ht
configuration"

The particular setting in which I noticed this was monitor mode:

	iwconfig wlan0 mode monitor
	ifconfig wlan0 up
	./iw wlan0 set channel 64 HT40-
	#./iw wlan0 set channel 64 HT40-
	tcpdump -i wlan0 -y IEEE802_11_RADIO

would only catch HT40 packets if I issued the IW command twice.

From visual inspection, iwl_set_rxon_channel does not depend on
iwl_set_rxon_ht, so simply swapping them should be safe and fixes this problem.

Patrick McHardy 9e2dcf7202 netfilter: nf_conntrack_reasm: properly handle packets fragmented into a single fragment
When an ICMPV6_PKT_TOOBIG message is received with a MTU below 1280,
all further packets include a fragment header.

Unlike regular defragmentation, conntrack also needs to "reassemble"
those fragments in order to obtain a packet without the fragment
header for connection tracking. Currently nf_conntrack_reasm checks
whether a fragment has either IP6_MF set or an offset != 0, which
makes it ignore those fragments.

Remove the invalid check and make reassembly handle fragment queues
containing only a single fragment.

Pablo Neira Ayuso a88e22adf5 netfilter: ctnetlink: fix creation of conntrack with helpers
This patch fixes a bug that triggers an assertion if you create
a conntrack entry with a helper and netfilter debugging is enabled.
Basically, we hit the assertion because the confirmation flag is
set before the conntrack extensions are added. To fix this, we
move the extension addition before the aforementioned flag is
set.

This patch also removes the possibility of setting a helper for
existing conntracks. This operation would also trigger the
assertion since we are not allowed to add new extensions for
existing conntracks. We know noone that could benefit from
this operation sanely.

Thanks to Eric Dumazet for initial posting a preliminary patch
to address this issue.

Arnd Bergmann b9fb9ee07e macvtap: add GSO/csum offload support
Added flags field to macvtap_queue to enable/disable processing of
virtio_net_hdr via IFF_VNET_HDR. This flag is checked to prepend virtio_net_hdr
in the receive path and process/skip virtio_net_hdr in the send path.

Original patch by Sridhar, further changes by Arnd.
