qlge_fix_features() is not supposed to modify hardware or
driver state, rather it is supposed to only fix requested
fetures bits. Currently qlge_fix_features() also goes for
interface down and up unnecessarily if there is not even
any change in features set.

This patch changes/fixes following -

1) Move reload of interface or device re-config from
   qlge_fix_features() to qlge_set_features().
2) Reload of interface in qlge_set_features() only if
   relevant feature bit (NETIF_F_HW_VLAN_CTAG_RX) is changed.
3) Get rid of qlge_fix_features() since driver is not really
   required to fix any features bit.

macb_reset_hw() is called from macb_close() and indirectly from
macb_open(). macb_reset_hw() zeroes the NCR register, including the MPE
(Management Port Enable) bit.

This will prevent accessing any other PHYs for other Ethernet MACs on
the MDIO bus, which remains registered at macb_reset_hw() time, until
macb_init_hw() is called from macb_open() which sets the MPE bit again.

I.e. currently the MDIO bus has a short disruption at open time and is
disabled at close time until the interface is opened again.

Fix that by only touching the RE and TE bits when enabling and disabling
RX/TX.

commit 739de9a1 ("net: macb: Reorganize macb_mii bringup") broke
initializing macb on the EVB-KSZ9477 eval board.
There, of_mdiobus_register was called even for the fixed-link representing
the RGMII-link to the switch with the result that the driver attempts to
enumerate PHYs on a non-existent MDIO bus:

	libphy: MACB_mii_bus: probed
	mdio_bus f0028000.ethernet-ffffffff: fixed-link has invalid PHY address
	mdio_bus f0028000.ethernet-ffffffff: scan phy fixed-link at address 0
        [snip]
	mdio_bus f0028000.ethernet-ffffffff: scan phy fixed-link at address 31

The "MDIO" bus registration succeeds regardless, having claimed the reset GPIO,
and calling of_phy_register_fixed_link later on fails because it tries
to claim the same GPIO:

	macb f0028000.ethernet: broken fixed-link specification

Fix this by registering the fixed-link before calling mdiobus_register.

When a bridge device is removed, the VLANs are flushed from each
configured port. This causes the ports to decrement the reference count
on the associated FIDs (filtering identifier). If the reference count of
a FID is 1 and it has a RIF (router interface), then this RIF is
destroyed.

However, if no port is member in the VLAN for which a RIF exists, then
the RIF will continue to exist after the removal of the bridge. To
reproduce:

# ip link add name br0 type bridge vlan_filtering 1
# ip link set dev swp1 master br0
# ip link add link br0 name br0.10 type vlan id 10
# ip address add 192.0.2.0/24 dev br0.10
# ip link del dev br0

The RIF associated with br0.10 continues to exist.

Fix this by iterating over all the bridge device uppers when it is
destroyed and take care of destroying their RIFs.

Intel Wired LAN Driver Updates 2018-08-24

This series contains fixes to e1000, igb, ixgb, ixgbe and i40e.

YueHaibing from Huawei provides a change to use dma_zalloc_coherent()
instead of calls to allocator followed by a memset for ixgb.

Bo Chen provides a couple of fixes for e1000, first by adding a check to
prevent a NULL pointer dereference.  The second change is to clean up a
possible resource leak on old transmit and receive rings when the device
is not up.

Jesus fixes an issue in the usage of an advanced transmit context
descriptor for retrieving the timestamp of a packet for AF_PACKET if the
IGB_TX_FLAGS_VLAN is not set in igb.

Jia-Ju Bai provides several patches which replace GFP_ATOMIC with
GFP_KERNEL, when using kzalloc() and kcalloc() which is not necessary.
Also found an instance of mdelay() call which could be replaced with
msleep().

Tony fixes ixgbe to allow MTU changes with XDP, by adding checks to
ensure only supported values and return -EINVAL for when it is not
supported.

Sebastian fixed an issue that was not clearing VF mailbox memory and
ensure queues are re-enabled correctly.

Martyna fixes a transmit timeout when DCB is configured when bringing up
an interface.

Jake fixes a previous commit which accidentally reversed the check of

On i210, Launchtime (TxTime) requires the usage of an "Advanced
Transmit Context Descriptor" for retrieving the timestamp of a packet.

The igb driver correctly builds such descriptor on the segmentation
flow (i.e. igb_tso()) or on the checksum one (i.e. igb_tx_csum()), but the
feature is broken for AF_PACKET if the IGB_TX_FLAGS_VLAN is not set,
which happens due to an early return on igb_tx_csum().

This flag is only set by the kernel when a VLAN interface is used,
thus we can't just rely on it. Here we are fixing this issue by checking
if launchtime is enabled for the current tx_ring before performing the
early return.

Intel Wired LAN Driver Fixes 2018-08-23

This series contains bug fixes to the ice driver.

Anirudh provides several fixes, starting with static analysis fixes by
replacing a bitwise-and with a constant value and replace "magic"
numbers with defines.  Fixed the control queue processing by removing
unnecessary read/writes to registers, as well as getting a accurate
value for "pending".  Added additional checks to avoid NULL pointer
dereferences.  Fixed up code formatting issues, by cleaning up code
comments and coding style.

Bruce cleans up a duplicate check for owner, within the same function.
Also cleans up interrupt causes that are not handled or applicable.
Fix checkpatch warning about the use of bool in structures due to the
wasted space and size of bool, so convert struct members to u8 instead.

Jake fixes a number of potential bugs in the reporting of stats via
ethtool, by simply reporting all the queue statistics, even for the
queues that are not activated.  Fixed a compiler warning, as well as
make the code a bit cleaner but just using order_base_2() for
calculating the power-of-2.

Preethi adds a check to avoid a NULL pointer dereference crash during
initialization.

Currently, we use a combination of ilog2 and is_power_of_2() to
calculate the next power of 2 for the qcount. This appears to be causing
a warning on some combinations of GCC and the Linux kernel:

MODPOST 1 modules
WARNING: "____ilog2_NaN" [ice.ko] undefined!

This appears to because because GCC realizes that qcount could be zero
in some circumstances and thus attempts to link against the
intentionally undefined ___ilog2_NaN function.

The order_base_2 function is intentionally defined to return 0 when
passed 0 as an argument, and thus will be safe to use here.

This not only fixes the warning but makes the resulting code slightly
cleaner, and is really what we should have used originally.

Also update the comment to make it more clear that we are rounding up,
not just incrementing the ilog2 of qcount unconditionally.

It is not safe to have the string table for statistics change order or
size over the lifetime of a given netdevice. This is because of the
nature of the 3-step process for obtaining stats. First, user space
performs a request for the size of the strings table. Second it performs
a separate request for the strings themselves, after allocating space
for the table. Third, it requests the stats themselves, also allocating
space for the table.

If the size decreased, there is potential to see garbage data or stats
values. In the worst case, we could potentially see stats values become
mis-aligned with their strings, so that it looks like a statistic is
being reported differently than it actually is.

Even worse, if the size increased, there is potential that the strings
table or stats table was not allocated large enough and the stats code
could access and write to memory it should not, potentially resulting in
undefined behavior and system crashes.

It isn't even safe if the size always changes under the RTNL lock. This
is because the calls take place over multiple user space commands, so it
is not possible to hold the RTNL lock for the entire duration of
obtaining strings and stats. Further, not all consumers of the ethtool
API are the user space ethtool program, and it is possible that one
assumes the strings will not change (valid under the current contract),
and thus only requests the stats values when requesting stats in a loop.

Finally, it's not possible in the general case to detect when the size
changes, because it is quite possible that one value which could impact
the stat size increased, while another decreased. This would result in
the same total number of stats, but reordering them so that stats no
longer line up with the strings they belong to. Since only size changes
aren't enough, we would need some sort of hash or token to determine
when the strings no longer match. This would require extending the
ethtool stats commands, but there is no more space in the relevant
structures.

The real solution to resolve this would be to add a completely new API
for stats, probably over netlink.

In the ice driver, the only thing impacting the stats that is not
constant is the number of queues. Instead of reporting stats for each
used queue, report stats for each allocated queue. We do not change the
number of queues allocated for a given netdevice, as we pass this into
the alloc_etherdev_mq() function to set the num_tx_queues and
num_rx_queues.

This resolves the potential bugs at the slight cost of displaying many
queue statistics which will not be activated.

When enable the config item "CONFIG_ARM64_64K_PAGES", the size of
PAGE_SIZE is 65536(64K). But the type of page_offset is u16, it will
overflow. So change it to u32, when "CONFIG_ARM64_64K_PAGES" enabled.

Commit 6edb3c96 ("net/ipv6: Defer initialization of dst to data path")
forgot to handle anycast route and init anycast rt->dst.input to ip6_forward.
Fix it by setting anycast rt->dst.input back to ip6_input.
