The EMAD workqueue is used to handle retransmission of EMAD packets that
contain configuration data for the device's firmware.

Given the workers need to allocate these packets and that the code is
not called as part of memory reclaim path, remove the WQ_MEM_RECLAIM
flag.

The driver cannot guarantee in the prepare phase that it will be able to
write an MDB entry to the device. In case the driver returned success
during the prepare phase, but then failed to add the entry in the commit
phase, a WARNING [1] will be generated by the switchdev core.

Fix this by doing the work in the prepare phase instead.

Restore SW_CRYPTO_CONTROL operation on AP_VLAN interfaces for unicast
keys, the original override was intended to be done for group keys as
those are treated specially by mac80211 and would always have been
rejected.

Now the situation is that AP_VLAN support must be enabled by the driver
if it can support it (meaning it can support software crypto GTK TX).

Thus, also simplify the code - if we get here with AP_VLAN and non-
pairwise key, software crypto must be used (driver doesn't know about
the interface) and can be used (driver must've advertised AP_VLAN if
it also uses SW_CRYPTO_CONTROL).

There is logic to check that the RX/TPA consumer index is the expected
index to work around a hardware problem.  However, the potentially bad
consumer index is first used to index into an array to reference an entry.
This can potentially crash if the bad consumer index is beyond legal
range.  Improve the logic to use the consumer index for dereferencing
after the validity check and log an error message.

ethtool: fix use of SPEED_UNKNOWN constant

This patch series addresses 2 related issues:

1. ethtool_validate_speed() triggers a "signed-unsigned comparison"
warning due to type difference of SPEED_UNKNOWN constant (int)
and argument to ethtool_validate_speed (__u32).

2. some drivers use u16 storage for SPEED_UNKNOWN constant,
resulting in value truncation and thus failure to test against
SPEED_UNKNOWN correctly.

This revised series addresses several feedback comments:
- split up the patch in to series
- do not unnecessarily change drivers that use "int" storage
  for speed values
====================
Signed-off-by: NDavid S. Miller <davem@davemloft.net>

qlcnic driver uses u16 to store SPEED_UKNOWN ethtool constant,
which is defined as -1, resulting in value truncation and
thus incorrect test results against SPEED_UNKNOWN.

For example, the following test will print "False":

    u16 speed = SPEED_UNKNOWN;

    if (speed == SPEED_UNKNOWN)
        printf("True");
    else
        printf("False");

Change storage of speed to use u32 to avoid this issue.

of affected users is big enough that we better switch off ASPM again.

This will hurt notebook users who are not affected by the issues, they
may see decreased battery runtime w/o ASPM. With the PCI core folks is

Currently there is no way for the driver to signal to mac80211 that it should
schedule a TXQ even if there are no packets on the mac80211 part of that queue.
This is problematic if the driver has an internal retry queue to deal with
software A-MPDU retry.

This patch changes the behavior of ieee80211_schedule_txq to always schedule
the queue, as its only user (ath9k) seems to expect such behavior already:
it calls this function on tx status and on powersave wakeup whenever its
internal retry queue is not empty.

Also add an extra argument to ieee80211_return_txq to get the same behavior.

This fixes an issue on ath9k where tx queues with packets to retry (and no
new packets in mac80211) would not get serviced.

When the mtu of a vrf device is set to 0, it would cause ping
failed. So I think we should limit vrf mtu in a reasonable range
to solve this problem. I set dev->min_mtu to IPV6_MIN_MTU, so it
will works for both ipv4 and ipv6. And if dev->max_mtu still be 0
can be confusing, so I set dev->max_mtu to ETH_MAX_MTU.

Here is the reproduce step:

1.Config vrf interface and set mtu to 0:
3: enp4s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel
master vrf1 state UP mode DEFAULT group default qlen 1000
    link/ether 52:54:00:9e:dd:c1 brd ff:ff:ff:ff:ff:ff

2.Ping peer:
3: enp4s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel
master vrf1 state UP group default qlen 1000
    link/ether 52:54:00:9e:dd:c1 brd ff:ff:ff:ff:ff:ff
    inet 10.0.0.1/16 scope global enp4s0
       valid_lft forever preferred_lft forever

Pull ARM SoC fixes from Olof Johansson:
 "A collection of fixes from the last few weeks. Most of them are
  smaller tweaks and fixes to DT and hardware descriptions for boards.
  Some of the more significant ones are:

   - eMMC and RGMII stability tweaks for rk3288

   - DDC fixes for Rock PI 4

   - Audio fixes for two TI am335x eval boards

   - D_CAN clock fix for am335x

   - Compilation fixes for clang

   - !HOTPLUG_CPU compilation fix for one of the new platforms this
     release (milbeaut)

   - A revert of a gpio fix for nomadik that instead was fixed in the
     gpio subsystem

   - Whitespace fix for the DT JSON schema (no tabs allowed)"

When HOTPLUG_CPU is disabled, some fields in the smp operations
are not available or needed:

arch/arm/mach-milbeaut/platsmp.c:90:3: error: field designator 'cpu_die' does not refer to any field in type
      'struct smp_operations'
        .cpu_die                = m10v_cpu_die,
         ^
arch/arm/mach-milbeaut/platsmp.c:91:3: error: field designator 'cpu_kill' does not refer to any field in type
      'struct smp_operations'
        .cpu_kill               = m10v_cpu_kill,
         ^

Hide them in an #ifdef like the other platforms do.

clang warns about statically defined DMA masks from the DMA_BIT_MASK
macro with length 64:

 arch/arm/mach-iop13xx/setup.c:303:35: error: shift count >= width of type [-Werror,-Wshift-count-overflow]
 static u64 iop13xx_adma_dmamask = DMA_BIT_MASK(64);
                                  ^~~~~~~~~~~~~~~~
 include/linux/dma-mapping.h:141:54: note: expanded from macro 'DMA_BIT_MASK'
 #define DMA_BIT_MASK(n) (((n) == 64) ? ~0ULL : ((1ULL<<(n))-1))
                                                      ^ ~~~

The ones in iop shouldn't really be 64 bit masks, so changing them
to what the driver can support avoids the warning.
