When netdev is down, the stack will delete the vlan from
hardware including vlan0, which will cause problem when
doing loopback selftest when netdev is down.

This patch fixes it by always preserving vlan 0 in hardware,
because vlan 0 is defalut vlan, which should always be in
hardware.

Full phylink support for mv88e6352

These two patches implement full phylink support for the mv88e6352
family, when using an SFP connected to its SERDES interface. This adds
interrupt support to the SERDES, so that we get interrupts on link
up/down, and then make calls phydev_link_change().

The first patch is a minor bug fix, which does not seem to affect any
current features, so i'm not submitting it for stable. It is however
required for configuring SERDES interrupts.

net: mvneta: some small improvements

patch1 removes the NETIF_F_GRO check ourself, because the net subsystem
will handle it for us.

patch2 enables NETIF_F_RXCSUM by default, since the driver and HW
supports the feature.

patch3 is a small optimization, to reduce smp_processor_id() calling
in mvneta_tx_done_gbe.

since v1:
 - based on net-next tree
 - remove the fix patches, since they should be based on net branch.

In the loop of mvneta_tx_done_gbe(), we call the smp_processor_id()
each time, move the call out of the loop to optimize the code a bit.

Before the patch, the loop looks like(under arm64):

        ldr     x1, [x29,#120]
        ...
        ldr     w24, [x1,#36]
        ...
        bl      0 <_raw_spin_lock>
        str     w24, [x27,#132]
        ...

After the patch, the loop looks like(under arm64):

        ...
        bl      0 <_raw_spin_lock>
        str     w23, [x28,#132]
        ...
where w23 is loaded so be ready before the loop.

>From another side, mvneta_tx_done_gbe() is called from mvneta_poll()
which is in non-preemptible context, so it's safe to call the
smp_processor_id() function once.

tokens and ctokens are defined as s64 in htb_class structure,
and clamped to 32bits value during netlink dumps:

cl->xstats.tokens = clamp_t(s64, PSCHED_NS2TICKS(cl->tokens),
                            INT_MIN, INT_MAX);

Defining it as u32 is working since userspace (tc) is printing it as
signed int, but a correct definition from the beginning is probably
better.

Added test case to receive multiple records with a single recvmsg()
operation with a MSG_PEEK set.
Signed-off-by: NDavid S. Miller <davem@davemloft.net>

When tls records are decrypted using asynchronous acclerators such as
NXP CAAM engine, the crypto apis return -EINPROGRESS. Presently, on
getting -EINPROGRESS, the tls record processing stops till the time the
crypto accelerator finishes off and returns the result. This incurs a
context switch and is not an efficient way of accessing the crypto
accelerators. Crypto accelerators work efficient when they are queued
with multiple crypto jobs without having to wait for the previous ones
to complete.

The patch submits multiple crypto requests without having to wait for
for previous ones to complete. This has been implemented for records
which are decrypted in zero-copy mode. At the end of recvmsg(), we wait
for all the asynchronous decryption requests to complete.

The references to records which have been sent for async decryption are
dropped. For cases where record decryption is not possible in zero-copy
mode, asynchronous decryption is not used and we wait for decryption
crypto api to complete.

For crypto requests executing in async fashion, the memory for
aead_request, sglists and skb etc is freed from the decryption
completion handler. The decryption completion handler wakesup the
sleeping user context when recvmsg() flags that it has done sending
all the decryption requests and there are no more decryption requests
pending to be completed.
