Using IPv6 flow-label to swiftly route around avoid congested or
disconnected network path can greatly improve TCP reliability.
This patch adds SNMP counters and a OPT_STATS counter to track both
host-level and connection-level statistics. Network administrators
can use these counters to evaluate the impact of this new ability better.
Export count for rehash attempts to
1) two SNMP counters: TcpTimeoutRehash (rehash due to timeouts),
and TcpDuplicateDataRehash (rehash due to receiving duplicate
packets)
2) Timestamping API SOF_TIMESTAMPING_OPT_STATS.

qeth_l?_stop_card() is _never_ called while in HARDSETUP state, and
there's no other usage of the card state that relies on the
DOWN -> HARDSETUP -> SOFTSETUP transition.
As related cleanup, remove the check in qeth_realloc_buffer_pool() as it
is already done by the callers.

When data is received on the READ channel, the matching logic for cmds
that are waiting for a reply is currently hard-coded into the channel's
main IO callback.
Move this into a per-cmd callback, so that we can apply custom matching
logic for each individual cmd.
This also allows us to remove the coarse-grained check for unexpected
non-IPA replies, since they will no longer match against _all_ pending
cmds.
Note that IDX cmds use _no_ matcher, since their reply is synchronously
received as part of the cmd's IO.

In fs_open(), 'vcc' is allocated through kmalloc() and assigned to
'atm_vcc->dev_data.' In the following execution, if an error occurs, e.g.,
there is no more free channel, an error code EBUSY or ENOMEM will be
returned. However, 'vcc' is not deallocated, leading to memory leaks. Note
that, in normal cases where fs_open() returns 0, 'vcc' will be deallocated
in fs_close(). But, if fs_open() fails, there is no guarantee that
fs_close() will be invoked.
To fix this issue, deallocate 'vcc' before the error code is returned.

when the block group is set read-only, preventing NOCOW writes to the

This has happend with scratch devices of size 12G but not with 5G and
20G, so this is depends on timing and other activity on the filesystem.
The whole replace operation is restartable, the space state should be
examined by the user in any case.
The error code is propagated back to the ioctl caller so the kernel
warning is causing false alerts.

The function busywait() is handy as a safety-latched variant of a while
loop. Many selftests deal specifically with counter values, and busywaiting
on them is likely to be rather common (it is not quite common now, but
busywait() has not been around for very long). To facilitate expressing
simply what is tested, introduce two helpers:
- until_counter_is(), which can be used as a predicate passed to
busywait(), which holds when expression, which is itself passed as an
argument to until_counter_is(), reaches a desired value.
- busywait_for_counter(), which is useful for waiting until a given counter
changes "by" (as opposed to "to") a certain amount.

In 2011, in commit b0460e4484f9 ("sch_tbf: report backlog information"),
TBF started copying backlog depth from the child Qdisc before dumping, with
the motivation that the backlog was otherwise not visible in "tc -s qdisc
show".
Later, in 2016, in commit 8d5958f424b6 ("sch_tbf: update backlog as well"),
TBF got a full-blown backlog tracking. However it kept copying the child's
backlog over before dumping.
That line is now unnecessary, so remove it.
As shown in the following example, backlog is still reported correctly:
# tc -s qdisc show dev veth0 invisible
qdisc tbf 1: root refcnt 2 rate 1Mbit burst 128Kb lat 82.8s

The cxgb3 driver for "Chelsio T3-based gigabit and 10Gb Ethernet
adapters" implements a custom ioctl as SIOCCHIOCTL/SIOCDEVPRIVATE in
cxgb_extension_ioctl().
One of the subcommands of the ioctl is CHELSIO_GET_MEM, which appears
to read memory directly out of the adapter and return it to userspace.
It's not entirely clear what the contents of the adapter memory
contains, but the assumption is that it shouldn't be accessible to all
users.
So add a CAP_NET_ADMIN check to the CHELSIO_GET_MEM case. Put it after
the is_offload() check, which matches two of the other subcommands in
the same function which also check for is_offload() and CAP_NET_ADMIN.

This patch adds support of XDP in native mode for hv_netvsc driver, and
transparently sets the XDP program on the associated VF NIC as well.
Setting / unsetting XDP program on synthetic NIC (netvsc) propagates to
VF NIC automatically. Setting / unsetting XDP program on VF NIC directly
is not recommended, also not propagated to synthetic NIC, and may be
overwritten by setting of synthetic NIC.
The Azure/Hyper-V synthetic NIC receive buffer doesn't provide headroom
for XDP. We thought about re-use the RNDIS header space, but it's too
small. So we decided to copy the packets to a page buffer for XDP. And,
most of our VMs on Azure have Accelerated Network (SRIOV) enabled, so
most of the packets run on VF NIC. The synthetic NIC is considered as a
fallback data-path. So the data copy on netvsc won't impact performance
significantly.
XDP program cannot run with LRO (RSC) enabled, so you need to disable LRO
before running XDP:
ethtool -K eth0 lro off
XDP actions not yet supported:

When TCP out-of-order is identified (unexpected tcp seq mismatch), driver
analyzes the packet and decides what handling should it get:
1. go to accelerated path (to be encrypted in HW),
2. go to regular xmit path (send w/o encryption),
3. drop.
Packets marked with skb->decrypted by the TLS stack in the TX flow skips
SW encryption, and rely on the HW offload.
Verify that such packets are never sent un-encrypted on the wire.
Add a WARN to catch such bugs, and prefer dropping the packet in these cases.

The call to tx_post_resync_params() is done earlier in the flow,
the post of the control WQEs is unnecessarily repeated. Remove it.

There are the following cases:
1. Packet ends before start marker: bypass offload.
2. Packet starts before start marker and ends after it: drop,
not supported, breaks contract with kernel.
3. packet ends before tls record info starts: drop,
this packet was already acknowledged and its record info
was released.
Add the above as comment in code.
Mind possible wraparounds of the TCP seq, replace the simple comparison
with a call to the TCP before() method.
In addition, remove logic that handles negative sync_len values,
as it became impossible.

Currently VF in LEGACY mode are not able to go up. Also in OFFLOADS
mode, when switching to it first time, VF can go up independently to
his representor, which is not expected.
Perform clearing of VF config when switching modes and set link state
to AUTO as default value. Also, when switching to OFFLOADS mode set
link state to DOWN, which allow VF link state to be controlled by its
REP.

Use raw_smp_processor_id instead of smp_processor_id() otherwise we will
get the following trace in debug-kernel:

Since the implementation relies on limiting the VF transmit rate to
simulate ingress rate limiting, and since either uplink representor or
ecpf are not associated with a VF, we limit the rate limit configuration
for those ports.

The current code handles only counters that attached to dest, we still
have the cases where we have counter on non-dest, like over drop etc.
