There's no point to force the caller to know about the internal
genl_sock to use inside struct net, just have them pass the network
namespace. This doesn't really change code generation since it's
an inline, but makes the caller less magic - there's never any
reason to pass another socket.

Here's one more bluetooth pull request for 3.19. We've got two fixes:
- Fix for accepting connections with old user space versions of BlueZ
- Fix for Bluetooth controllers that don't have a public address
Both of these are regressions that were introduced in 3.17, so the
appropriate Cc: stable annotations are provided.
Please let me know if there are any issues pulling. Thanks.

GSO isn't the only offload feature with restrictions that
potentially can't be expressed with the current features mechanism.
Checksum is another although it's a general issue that could in
theory apply to anything. Even if it may be possible to
implement these restrictions in other ways, it can result in
duplicate code or inefficient per-packet behavior.
This generalizes ndo_gso_check so that drivers can remove any
features that don't make sense for a given packet, similar to
netif_skb_features(). It also converts existing driver
restrictions to the new format, completing the work that was
done to support tunnel protocols since the issues apply to
checksums as well.
By actually removing features from the set that are used to do
offloading, it solves another problem with the existing
interface. In these cases, GSO would run with the original set
of features and not do anything because it appears that
segmentation is not required.

Use generic config_init callback also for KSZ8021 and KSZ8031.

becomes unresponsive if the broadcast-disable flag is set before
configuring the clock mode.

When using VXLAN tunnels and a sky2 device, I have experienced
checksum failures of the following type:
[ 4297.761899] eth0: hw csum failure
[...]
[ 4297.765223] Call Trace:
[ 4297.765224] <IRQ> [<ffffffff8172f026>] dump_stack+0x46/0x58
[ 4297.765235] [<ffffffff8162ba52>] netdev_rx_csum_fault+0x42/0x50

[ 4297.765246] [<ffffffff81666ca0>] ? ip_rcv_finish+0x360/0x360
These are reliably reproduced in a network topology of:
container:eth0 == host(OVS VXLAN on VLAN) == bond0 == eth0 (sky2) -> switch
When VXLAN encapsulated traffic is received from a similarly
configured peer, the above warning is generated in the receive
processing of the encapsulated packet. Note that the warning is
associated with the container eth0.
The skbs from sky2 have ip_summed set to CHECKSUM_COMPLETE, and
because the packet is an encapsulated Ethernet frame, the checksum
generated by the hardware includes the inner protocol and Ethernet
headers.
The receive code is careful to update the skb->csum, except in
__dev_forward_skb, as called by dev_forward_skb. __dev_forward_skb
calls eth_type_trans, which in turn calls skb_pull_inline(skb, ETH_HLEN)
to skip over the Ethernet header, but does not update skb->csum when
doing so.
This patch resolves the problem by adding a call to
skb_postpull_rcsum to update the skb->csum after the call to
eth_type_trans.

The __ldcw macro has a problem when its argument needs to be reloaded from
memory. The output memory operand and the input register operand both need to
be reloaded using a register in class R1_REGS when generating 64-bit code.
This fails because there's only a single register in the class. Instead, use a

When controllers set the HCI_QUIRK_INVALID_BDADDR flag, it is required
by userspace to program a valid public Bluetooth device address into
the controller before it can be used.
After successful address configuration, the internal state changes and
the controller runs the complete initialization procedure. However one
small difference is that this is no longer the HCI_SETUP stage. The
HCI_SETUP stage is only valid during initial controller setup. In this
case the stack runs the initialization as part of the HCI_CONFIG stage.
The controller version information, default name and supported commands
are only stored during HCI_SETUP. While these information are static,
they are not read initially when HCI_QUIRK_INVALID_BDADDR is set. So
when running in HCI_CONFIG state, these information need to be updated
as well.
This especially impacts Bluetooth 4.1 and later controllers using
extended feature pages and second event mask page.
