We can not use the standard sg_set_buf() fucntion since when
CONFIG_DEBUG_SG=y this adds a check that will BUG_ON for cifs.ko
when we pass it an object from the stack.
Create a new wrapper smb2_sg_set_buf() which avoids doing that particular check
and use it for smb3 encryption instead.

Prior to this patch, when one packet is hashed into path [1]
(hash <= nh_upper_bound) and it's neigh is dead, it will try
path [2]. However, if path [2]'s neigh is alive but it's
hash > nh_upper_bound, it will not return this alive path.
This packet will never be sent even if path [2] is alive.
3.3.3.1/24:
nexthop via 1.1.1.254 dev eth1 weight 1 <--[1] (dead neigh)
nexthop via 2.2.2.254 dev eth2 weight 1 <--[2]
With sysctl_fib_multipath_use_neigh set is supposed to find an
available path respecting to the l3/l4 hash. But if there is
no available route with this hash, it should at least return
an alive route even with other hash.
This patch is to fix it by processing fib_multipath_use_neigh
earlier than the hash check, so that it will at least return
an alive route if there is when fib_multipath_use_neigh is
enabled. It's also compatible with before when there are alive
routes with the l3/l4 hash.

The default TX moderation mode was mistakenly set to CQE based. The
intention was to add a control ability in order to improve some specific
use-cases. In general, we prefer to use EQE based moderation as it gives
much better numbers for the common cases.
CQE based causes a degradation in the common case since it resets the
moderation timer on CQE generation. This causes an issue when TSO is
well utilized (large TSO sessions). The timer is set to 16us so traffic
of ~64KB TSO sessions per second would mean timer reset (CQE per TSO
session -> long time between CQEs). In this case we quickly reach the
tcp_limit_output_bytes (256KB by default) and cause a halt in TX traffic.
By setting EQE based moderation we make sure timer would expire after
16us regardless of the packet rate.
This fixes an up to 40% packet rate and up to 23% bandwidth degradtions.

When the driver is closed, all the associated irqs are disabled. In the
event that the driver exits a reset in the closed state, we should be
consistent with the state we are in directly after a close. So before we
exit the reset routine, all irqs should be disabled as well. This will
prevent the irqs from being enabled twice in this case and reporting a
number of noisy warning traces.

Each Oracle DAX CCB has a corresponding completion area, and the required
number of areas must fit within a previously allocated array of completion
areas beginning at the requested index. Since the completion area index
is specified by a file offset, a user can pass arbitrary values, including
negative numbers. So the index must be thoroughly range checked to prevent
access to addresses outside the bounds of the allocated completion
area array. The index cannot be negative, and it cannot exceed the
total array size, less the number of CCBs requested. The old code did
not check for negative values and was off by one on the upper bound.

inet: factorize sk_wmem_alloc updates
While testing my inet defrag changes, I found that senders
could spend ~20% of cpu cycles in skb_set_owner_w() updating
sk->sk_wmem_alloc for every fragment they cook, competing
with TX completion of prior skbs possibly happening on another cpus.
One solution to this problem is to use alloc_skb() instead
of sock_wmalloc() and manually perform a single sk_wmem_alloc change.
This greatly increases speed for applications sending big UDP datagrams.

In commit 145307460ba9 ("devlink: Remove top_hierarchy arg to
devlink_resource_register"), the "top_hierarchy" parameter to
devlink_resource_register() was removed in favor of using the parameter
"parent_resource_id" exclusively to determine who the parent is. The
root node's resource ID for this purpose is
DEVLINK_RESOURCE_ID_PARENT_TOP with the value 0. It is therefore
problematic that the resource MLXSW_SP_RESOURCE_KVD has also ID of 0.
Fix this by numbering driver-specific resources from 1.

The parts info is array. The parts copy this info array, yet they are a
list. So make the indexing according to the id and change the list of
parts into array of parts. This helps to eliminate lookups and
constructs like mlxsw_sp_kvdl_part_update() (took me some non-trivial
