net: ethernet: remove unnecessary pci_set_drvdata() part 1

Since commit 0998d063
(device-core: Ensure drvdata = NULL when no driver is bound),
the driver core clears the driver data to NULL after device_release

This is a batch of updates intended for the 3.13 stream...

The biggest item of interest in here is wcn36xx, the new mac80211
driver for Qualcomm WCN3660/WCN3680 hardware.

Regarding the mac80211 bits, Johannes says:

"We have an assortment of cleanups and new features, of which the
biggest one is probably the channel-switch support in IBSS. Nothing
else really stands out much."

On top of that, the ath9k and rt2x00 get a lot of update action from
Felix Fietkau and Gabor Juhos, respectively.  There are a handful of
updates to other drivers here and there as well.

xen-netback: IPv6 offload support

====================
This patch series adds support for checksum and large packet offloads
into xen-netback.  Testing has mainly been done using the Microsoft
network hardware certification suite running in Server 2008R2 VMs with
Citrix PV frontends.

v2:
- Fixed Wei's email address in Cc lines

v3:
- Responded to Wei's comments:
 - netif.h now updated with comments and a definition of
   XEN_NETIF_GSO_TYPE_NONE.
 - limited number of pullups
- Responded to Annie's comments:
 - New GSO_BIT macro

v4:
- Responded to more of Wei's comments
- Remove parsing of IPv6 fragment header and added warning

v5:
- Added comment concerning the value chosen for PKT_PROT_LEN
- Dropped deprecation of feature-no-csum-offload
====================

This patch adds code to handle SKB_GSO_TCPV6 skbs and construct appropriate
extra or prefix segments to pass the large packet to the frontend. New

to determine if the frontend is capable of handling such packets.

For performance of VM to VM traffic on a single host it is better to avoid
calculation of TCP/UDP checksum in the sending frontend. To allow this this

and xenstore flag feature-ipv6-csum-offload to advertise that fact to

netfilter updates: nf_tables pull request

The following patchset contains the current original nf_tables tree
condensed in 17 patches. I have organized them by chronogical order
since the original nf_tables code was released in 2009 and by
dependencies between the different patches.

The patches are:

1) Adapt all existing hooks in the tree to pass hook ops to the
   hook callback function, required by nf_tables, from Patrick McHardy.

2) Move alloc_null_binding to nf_nat_core, as it is now also needed by
   nf_tables and ip_tables, original patch from Patrick McHardy but
   required major changes to adapt it to the current tree that I made.

3) Add nf_tables core, including the netlink API, the packet filtering
   engine, expressions and built-in tables, from Patrick McHardy. This
   patch includes accumulated fixes since 2009 and minor enhancements.
   The patch description contains a list of references to the original
   patches for the record. For those that are not familiar to the
   original work, see [1], [2] and [3].

4) Add netlink set API, this replaces the original set infrastructure
   to introduce a netlink API to add/delete sets and to add/delete
   set elements. This includes two set types: the hash and the rb-tree
   sets (used for interval based matching). The main difference with
   ipset is that this infrastructure is data type agnostic. Patch from
   Patrick McHardy.

5) Allow expression operation overload, this API change allows us to
   provide define expression subtypes depending on the configuration
   that is received from user-space via Netlink. It is used by follow
   up patches to provide optimized versions of the payload and cmp
   expressions and the x_tables compatibility layer, from Patrick
   McHardy.

6) Add optimized data comparison operation, it requires the previous
   patch, from Patrick McHardy.

7) Add optimized payload implementation, it requires patch 5, from
   Patrick McHardy.

8) Convert built-in tables to chain types. Each chain type have special
   semantics (filter, route and nat) that are used by userspace to
   configure the chain behaviour. The main chain regarding iptables
   is that tables become containers of chain, with no specific semantics.
   However, you may still configure your tables and chains to retain
   iptables like semantics, patch from me.

9) Add compatibility layer for x_tables. This patch adds support to
   use all existing x_tables extensions from nf_tables, this is used
   to provide a userspace utility that accepts iptables syntax but
   used internally the nf_tables kernel core. This patch includes
   missing features in the nf_tables core such as the per-chain
   stats, default chain policy and number of chain references, which
   are required by the iptables compatibility userspace tool. Patch
   from me.

10) Fix transport protocol matching, this fix is a side effect of the
    x_tables compatibility layer, which now provides a pointer to the
    transport header, from me.

11) Add support for dormant tables, this feature allows you to disable
    all chains and rules that are contained in one table, from me.

12) Add IPv6 NAT support. At the time nf_tables was made, there was no
    NAT IPv6 support yet, from Tomasz Bursztyka.

13) Complete net namespace support. This patch register the protocol
    family per net namespace, so tables (thus, other objects contained
    in tables such as sets, chains and rules) are only visible from the
    corresponding net namespace, from me.

14) Add the insert operation to the nf_tables netlink API, this requires
    adding a new position attribute that allow us to locate where in the
    ruleset a rule needs to be inserted, from Eric Leblond.

15) Add rule batching support, including atomic rule-set updates by
    using rule-set generations. This patch includes a change to nfnetlink
    to include two new control messages to indicate the beginning and
    the end of a batch. The end message is interpreted as the commit
    message, if it's missing, then the rule-set updates contained in the
    batch are aborted, from me.

16) Add trace support to the nf_tables packet filtering core, from me.

17) Add ARP filtering support, original patch from Patrick McHardy, but
    adapted to fit into the chain type infrastructure. This was recovered
    to be used by nft userspace tool and our compatibility arptables
    userspace tool.

There is still work to do to fully replace x_tables [4] [5] but that can
be done incrementally by extending our netlink API. Moreover, looking at
netfilter-devel and the amount of contributions to nf_tables we've been
getting, I think it would be good to have it mainstream to avoid accumulating
large patchsets skip continuous rebases.

I tried to provide a reasonable patchset, we have more than 100 accumulated
patches in the original nf_tables tree, so I collapsed many of the small
fixes to the main patch we had since 2009 and provide a small batch for
review to netdev, while trying to retain part of the history.

For those who didn't give a try to nf_tables yet, there's a quick howto
available from Eric Leblond that describes how to get things working [6].

Comments/reviews welcome.

Thanks!
