When matching on the ICMPv6 code ICMPV6_CODE rather than
ICMPV4_CODE attributes should be used.

This corrects what appears to be a typo.

Sample usage:

tc qdisc add dev eth0 ingress
tc filter add dev eth0 protocol ipv6 parent ffff: flower \
	indev eth0 ip_proto icmpv6 type 128 code 0 action drop

Without this change the code parameter above is effectively ignored.

Some Hypervisors detach VFs from VMs by instantly causing an FLR event
to be generated for a VF.

In the mlx4 case, this will cause that VF's comm channel to be disabled
before the VM has an opportunity to invoke the VF device's "shutdown"
method.

The result is that the VF driver on the VM will experience a command
timeout during the shutdown process when the Hypervisor does not deliver
a command-completion event to the VM.

To avoid FW command timeouts on the VM when the driver's shutdown method
is invoked, we detect the absence of the VF's comm channel at the very
start of the shutdown process. If the comm-channel has already been
disabled, we cause all FW commands during the device shutdown process to
immediately return success (and thus avoid all command timeouts).

In spite of switching to paged allocation of Rx buffers, the driver still
called dma_unmap_single() in the Rx queues tear-down path.

The DMA region unmapping code in free_skb_rx_queue() basically predates
the introduction of paged allocation to the driver. While being refactored,
it apparently hasn't reflected the change in the DMA API usage by its
counterpart gfar_new_page().

As a result, setting an interface to the DOWN state now yields the following:

  # ip link set eth2 down

Zhang Yanmin reported crashes [1] and provided a patch adding a
synchronize_rcu() call in can_rx_unregister()

The main problem seems that the sockets themselves are not RCU
protected.

If CAN uses RCU for delivery, then sockets should be freed only after
one RCU grace period.

Recent kernels could use sock_set_flag(sk, SOCK_RCU_FREE), but let's
ease stable backports with the following fix instead.

DW GMAC databook says the following about bits in "Register 15 (Interrupt
Mask Register)":
--------------------------->8-------------------------
When set, this bit __disables_the_assertion_of_the_interrupt_signal__
because of the setting of XXX bit in Register 14 (Interrupt
Status Register).
--------------------------->8-------------------------

In fact even if we mask one bit in the mask register it doesn't prevent
corresponding bit to appear in the status register, it only disables
interrupt generation for corresponding event.

But currently we expect a bit different behavior: status bits to be in
sync with their masks, i.e. if mask for bit A is set in the mask
register then bit A won't appear in the interrupt status register.

This was proven to be incorrect assumption, see discussion here [1].
That misunderstanding causes unexpected behaviour of the GMAC, for
example we were happy enough to just see bogus messages about link
state changes.

So from now on we'll be only checking bits that really may trigger an
interrupt.

Modifying TIR hash should change selected fields bitmask in addition to
the function and key.

Formerly, Only on ethool mlx5e_set_rxfh "ethtoo -X" we would not set this
field resulting in zeroing of its value, which means no packet fields are
used for RX RSS hash calculation thus causing all traffic to arrive in
RQ[0].

On driver load out of the box we don't have this issue, since the TIR
hash is fully created from scratch.

Tested:
ethtool -X ethX hkey  <new key>
ethtool -X ethX hfunc <new func>
ethtool -X ethX equal <new indirection table>

All cases are verified with TCP Multi-Stream traffic over IPv4 & IPv6.

When tunneling is used, some virtualizations systems set the (mlx5e) uplink
device to be stacked under upper devices such as bridge or ovs internal
port, where the VTEP IP address used for the encapsulation is set on
that upper device.

In order to support such use-cases, we also deal with a setup where the
egress mirred device isn't representing a port on the HW e-switch to where
the ingress device belongs. We use eswitch service function which returns
the uplink and set it as the egress device of the tc encap rule.

If IPV6 has not been enabled in the underlying kernel, we must avoid
calling IPV6 procedures in rdma_cm.ko.

This requires using "IS_ENABLED(CONFIG_IPV6)" in "if" statements
surrounding any code which calls external IPV6 procedures.

In the instance fixed here, procedure cma_bind_addr() called
ipv6_addr_type() -- which resulted in calling external procedure
__ipv6_addr_type().

Please pull in your 'for-linus' branch two little fixes for Xen

One fix is for handling the XEN_PAGE_SIZE != PAGE_SIZE (4KB vs 64KB

Quotacheck runs at mount time in situations where quota accounting must
be recalculated. In doing so, it uses bulkstat to visit every inode in
the filesystem. Historically, every inode processed during quotacheck
was released and immediately tagged for reclaim because quotacheck runs
before the superblock is marked active by the VFS. In other words,
the final iput() lead to an immediate ->destroy_inode() call, which
allowed the XFS background reclaim worker to start reclaiming inodes.

Commit 17c12bcd ("xfs: when replaying bmap operations, don't let
unlinked inodes get reaped") marks the XFS superblock active sooner as
part of the mount process to support caching inodes processed during log
recovery. This occurs before quotacheck and thus means all inodes
processed by quotacheck are inserted to the LRU on release.  The
s_umount lock is held until the mount has completed and thus prevents
the shrinkers from operating on the sb. This means that quotacheck can
excessively populate the inode LRU and lead to OOM conditions on systems
without sufficient RAM.

Update the quotacheck bulkstat handler to set XFS_IGET_DONTCACHE on
inodes processed by quotacheck. This causes ->drop_inode() to return 1
and in turn causes iput_final() to evict the inode. This preserves the
original quotacheck behavior and prevents it from overloading the LRU
and running out of memory.

With some gcc versions, we get a warning about the eicon driver,
and that currently shows up as the only remaining warning in one
of the build bots:

In file included from ../drivers/isdn/hardware/eicon/message.c:30:0:
eicon/message.c: In function 'mixer_notify_update':
eicon/platform.h:333:18: warning: array subscript is above array bounds [-Warray-bounds]

The code is easily changed to open-code the unusual PUT_WORD() line
causing this to avoid the warning.
