Changes to cpsw and davinci_emac for getting MAC address
Here are a few patches to add common code for cpsw and davinci_emac for
getting the MAC address. Looks like we can also now add code to get the
MAC address on 3517 but in a slightly different way.

Looks like on 3517 davinci_emac MAC address registers have a
different layout compared to dm816x and am33xx.
Let's add a function to get the 3517 MAC address.

At least on dm81xx, we can get the davinci_emac MAC address the same
way as on am33xx cpsw.
Let's also use ether_addr_copy() for davinci_emac while at it.

Looks like davinci_emac and cpsw can share some code although the
device registers have a different layout.
At least the code for getting the MAC address using syscon can
be shared by passing the register offset. Let's start with that
and set up a minimal shared cpsw-shared.c.

this is a pull request of 12 patches for net-next/master.
There are 3 patches by Ahmed S. Darwish, which update the kvaser_usb
driver and add support for the USBcan-II based adapters. Stéphane
Grosjean contributes 7 patches for the peak_usb driver, which add
support for the CANFD USB adapters. I contribute 2 patches which clean
up the peak_usb driver structure a bit.

When many pf_packet listeners are created on a lot of interfaces the
current implementation using global packet type lists scales poorly.
This patch adds per net_device packet type lists to fix this problem.
The patch was originally written by Eric Biederman for linux-2.6.29.
Tested on linux-3.16.

When IFLA_LINK_NETNSID is used, the netdevice should be built in this link netns
and moved at the end to another netns (pointed by the socket netns or
IFLA_NET_NS_[PID|FD]).
Existing user of the newlink handler will use the netns argument (src_net) to
find a link netdevice or to check some other information into the link netns.
For example, to find a netdevice, two information are required: an ifindex
(usually from IFLA_LINK) and a netns (this link netns).
Note: when using IFLA_LINK_NETNSID and IFLA_NET_NS_[PID|FD], a user may create a
netdevice that stands in netnsX and with its link part in netnsY, by sending a
rtnl message from netnsZ.

TIME_WAIT sockets are not owning any skb.
ip_send_unicast_reply() and tcp_v6_send_response() both use
regular sockets.
We can safely remove a test in sch_fq and save one cache line miss,
as sk_state is far away from sk_pacing_rate.
Tested at Google for about one year.

NET_ACT_CONNMARK fails to build if NF_CONNTRACK_MARK is disabled,
and d7924450e1 ("act_connmark: Add missing dependency on
NF_CONNTRACK_MARK") fixed that case, but missed the cased where
NF_CONNTRACK is a loadable module.
This adds the second dependency to ensure that NET_ACT_CONNMARK
can only be built-in if NF_CONNTRACK is also part of the kernel
rather than a loadable module.

The sock_iocb structure is allocate on stack for each read/write-like
operation on sockets, and contains various fields of which only the
embedded msghdr and sometimes a pointer to the scm_cookie is ever used.
Get rid of the sock_iocb and put a msghdr directly on the stack and pass
the scm_cookie explicitly to netlink_mmap_sendmsg.

NFC: 3.20 first pull request
This is the first NFC pull request for 3.20.
With this one we have:
- Secure element support for the ST Micro st21nfca driver. This depends
on a few HCI internal changes in order for example to support more
than one secure element per controller.
- ACPI support for NXP's pn544 HCI driver. This controller is found on
many x86 SoCs and is typically enumerated on the ACPI bus there.
- A few st21nfca and st21nfcb fixes.
