4a1836701f net: skfb: remove obsolete -I cflag
The skfp driver has been moved to drivers/net/fddi/skfp a long time
ago, but we still attempt to include headers from the old location,
which causes a warning when building with W=1:

cc1: error: /git/arm-soc/drivers/net/skfp: No such file or directory [-Werror=missing-include-dirs]
cc1: error: drivers/net/skfp: No such file or directory [-Werror=missing-include-dirs]

Clearly this include directive is not needed any more, so we can
just remove it now.

810e530bfa net: vrf: Switch dst dev to loopback on device delete
Attempting to delete a VRF device with a socket bound to it can stall:

  unregister_netdevice: waiting for red to become free. Usage count = 1

The unregister is waiting for the dst to be released and with it
references to the vrf device. Similar to dst_ifdown switch the dst
dev to loopback on delete for all of the dst's for the vrf device
and release the references to the vrf device.

a78c16e1b9 mdio: mux: avoid 'maybe-uninitialized' warning
The latest changes to the MDIO code introduced a false-positive
warning with gcc-6 (possibly others):

drivers/net/phy/mdio-mux.c: In function 'mdio_mux_init':
drivers/net/phy/mdio-mux.c:188:3: error: 'parent_bus_node' may be used uninitialized in this function [-Werror=maybe-uninitialized]

It's easy to avoid the warning by making sure the parent_bus_node
is initialized in both cases at the start of the function, since
the later 'of_node_put()' call is also valid for a NULL pointer
argument.

df10db98ab tun: fix csum generation for tap devices
The commit 3416609363 ("tuntap: use common code for virtio_net_hdr
and skb GSO conversion") replaced the tun code for header manipulation
with the generic helpers. While doing so, it implictly moved the
skb_partial_csum_set() invocation after eth_type_trans(), which
invalidate the current gso start/offset values.
Fix it by moving the helper invocation before the mac pulling.

9ff7438460 net: vrf: Handle ipv6 multicast and link-local addresses
IPv6 multicast and link-local addresses require special handling by the
VRF driver:
1. Rather than using the VRF device index and full FIB lookups,
   packets to/from these addresses should use direct FIB lookups based on
   the VRF device table.

2. fail sends/receives on a VRF device to/from a multicast address
   (e.g, make ping6 ff02::1%<vrf> fail)

3. move the setting of the flow oif to the first dst lookup and revert
   the change in icmpv6_echo_reply made in ca254490c8 ("net: Add VRF
   support to IPv6 stack"). Linklocal/mcast addresses require use of the
   skb->dev.

With this change connections into and out of a VRF enslaved device work
for multicast and link-local addresses work (icmp, tcp, and udp)
e.g.,

1. packets into VM with VRF config:
    ping6 -c3 fe80::e0:f9ff:fe1c:b974%br1
    ping6 -c3 ff02::1%br1

    ssh -6 fe80::e0:f9ff:fe1c:b974%br1

2. packets going out a VRF enslaved device:
    ping6 -c3 fe80::18f8:83ff:fe4b:7a2e%eth1
    ping6 -c3 ff02::1%eth1
    ssh -6 root@fe80::18f8:83ff:fe4b:7a2e%eth1

0c5ddb51e8 net/mlx4_en: initialize cmd.context_lock spinlock earlier
Maciej Żenczykowski reported lockdep warning a spinlock
was not registered before being held in mlx4_cmd_wake_completions()

cmd.context_lock initialization is not at the right place.

1) mlx4_cmd_use_events() can be called multiple times.
   Calling spin_lock_init() on a live spinlock can lead
   to hangs.

2) mlx4_cmd_wake_completions() can be called while lock
   has not been initialized.
   Lockdep complains, and current logic is not race prone.

It seems better to move the initialization earlier in
mlx4_load_one()

Second, the settings are independent with the others.

Last, the settings may take more time than the others. Leave

cf6645f8eb bnxt_en: Add function for VF driver to query default VLAN.
The PF can setup a default VLAN for a VF.  The default VLAN tag is
automatically inserted and stripped without the knowledge of the
stack running on the VF.  The VF driver needs to know that default
VLAN is enabled as VLAN acceleration on the RX side is no longer
supported.  Call netdev_update_features() to fix up the VLAN features
as necessary.  Also, VLAN strip mode must be enabled to strip out
the default VLAN tag.

Only allow VF default VLAN to be set if the firmware spec is >= 1.2.1.

881d0327db net: alx: Work around the DMA RX overflow issue
Commit 26c5f03 uses a new skb allocator to avoid the RFD overflow
issue.

But from debugging without datasheet, we found the error always
happen when the DMA RX address is set to 0x....fc0, which is very
likely to be a HW/silicon problem.

So one idea is instead of adding a new allocator, why not just
hitting the right target by avaiding the error-prone DMA address?

This patch will actually
* Remove the commit 26c5f03
* Apply rx skb with 64 bytes longer space, and if the allocated skb
  has a 0x...fc0 address, it will use skb_resever(skb, 64) to
  advance the address, so that the RX overflow can be avoided.

In theory this method should also apply to atl1c driver, which
I can't find anyone who can help to test on real devices.

fdecf36fce phy: marvell: fix LED configuration via marvell,reg-init
Configuring the PHY LED registers for the Marvell 88E1510 and others is
not possible, because regardless of the values in marvell,reg-init, it
is later overridden in m88e1121_config_aneg with a non-standard default.

This patch moves that default configuration to .config_init to allow
setting the LED configuration through marvell,reg-init in the device
tree, which should override said default if it exists.

5c87a55adb mwifiex: remove misleading GFP_DMA flag in buffer allocations
The GFP_DMA flag is obviously misunderstood in the mwifiex driver. It's
meant for legacy ISA DMA memory mappings only -- the lower 16MB on x86.
That doesn't apply to PCIe or SDIO devices, I guess.

Remove the GFP_DMA flag to reduce the need to place the socket buffer
allocation into the low mem DMA area, which might already be in use by
other drivers.

This misuse was flagged by the PaX USERCOPY feature by chance, as it
detected the user copy operation from a DMA buffer in the recvfrom()
syscall path.

This is important for brcmfmac as some of released firmwares (e.g.
brcmfmac4366b-pcie.bin) may pick different channel than requested. This
has been tested with BCM4366B1 in D-Link DIR-885L.

4712d88a57 brcmutil: add field storing control channel to the struct brcmu_chan
Our d11 code supports encoding/decoding channel info into/from chanspec
format used by firmware. Current implementation is quite misleading
because of the way "chnum" field is used.
When encoding channel info, "chnum" has to be filled by a caller with
*center* channel number. However when decoding chanspec the same field
is filled with a *control* channel number.

1) This can be confusing. It's expected for information to be the same
   after encoding and decoding.
2) It doesn't allow accessing all info when decoding. Some functions may
   need to know both channel numbers, e.g. cfg80211 callback getting
   current channel.
Solve this by adding a separated field for control channel.
