/*
* The dn_dev_parms structure contains the set of parameters
* for each device (hence inclusion in the dn_dev structure)
* and an array is used to store the default types of supported
* device (in dn_dev.c).
*
* The type field matches the ARPHRD_ constants and is used in
* searching the list for supported devices when new devices
* come up.
*
* The mode field is used to find out if a device is broadcast,
* multipoint, or pointopoint. Please note that DECnet thinks
* different ways about devices to the rest of the kernel
* so the normal IFF_xxx flags are invalid here. For devices
* which can be any combination of the previously mentioned
* attributes, you can set this on a per device basis by
* installing an up() routine.
*
* The device state field, defines the initial state in which the
* device will come up. In the dn_dev structure, it is the actual
* state.
*
* Things have changed here. I've killed timer1 since it's a user space
* issue for a user space routing deamon to sort out. The kernel does
* not need to be bothered with it.
*
* Timers:
* t2 - Rate limit timer, min time between routing and hello messages
* t3 - Hello timer, send hello messages when it expires
*
* Callbacks:
* up() - Called to initialize device, return value can veto use of
* device with DECnet.
* down() - Called to turn device off when it goes down
* timer3() - Called once for each ifaddr when timer 3 goes off
*
* sysctl - Hook for sysctl things

The mv88e6390 Ethernet switch has internal PHYs. These PHYs don't have
an model ID in the ID2 register. So the MDIO driver in the switch
intercepts reads to this register, and returns the switch family ID.
Extend the Marvell PHY driver by including this ID, and treat the PHY
as a 88E1540.

Pull networking fixes from David Miller:
1) Fix handling of interrupt status in stmmac driver. Just because we
have masked the event from generating interrupts, doesn't mean the
bit won't still be set in the interrupt status register. From Alexey
Brodkin.
2) Fix DMA API debugging splats in gianfar driver, from Arseny Solokha.
3) Fix off-by-one error in __ip6_append_data(), from Vlad Yasevich.
4) cls_flow does not match on icmpv6 codes properly, from Simon Horman.
5) Initial MAC address can be set incorrectly in some scenerios, from
Ivan Vecera.
6) Packet header pointer arithmetic fix in ip6_tnl_parse_tlv_end_lim(),
from Dan Carpenter.
7) Fix divide by zero in __tcp_select_window(), from Eric Dumazet.
8) Fix crash in iwlwifi when unregistering thermal zone, from Jens
Axboe.
9) Check for DMA mapping errors in starfire driver, from Alexey
Khoroshilov.

Kalle Valo says:
====================
wireless-drivers-next patches for 4.11
It's nice to see rt2x00 development has becoming active, for example
adding support for a new chip version. Also wcn36xx has been converted
to use the recently merged QCOM_SMD subsystem. Otherwise new features
and fixes it lots of drivers.
Major changes:
iwlwifi
* some more work in preparation for A000 family support
* add support for radiotap timestamps
* some work on our firmware debugging capabilities
wcn36xx
* convert to a proper QCOM_SMD driver (from the platform_driver interface)
ath10k
* VHT160 support
* dump Copy Engine registers during firmware crash
* search board file extension from SMBIOS
wil6210
* add disable_ap_sme module parameter
rt2x00
* support RT3352 with external PA
* support for RT3352 with 20MHz crystal
* add support for RT5350 WiSoC
brcmfmac
* add support for BCM43455 sdio device
rtl8xxxu
* add support for D-Link DWA-131 rev E1, TP-Link TL-WN822N v4 and others

Commit cdba756f5803a2 ("net: move ndo_features_check() close to
ndo_start_xmit()") inadvertently moved the doc comment for
.ndo_fix_features instead of .ndo_features_check. Fix the comment
ordering.
