This patch is to allow matching options in erspan.
The options can be described in the form:
VER:INDEX:DIR:HWID/VER:INDEX_MASK:DIR_MASK:HWID_MASK.
When ver is set to 1, index will be applied while dir
and hwid will be ignored, and when ver is set to 2,
dir and hwid will be used while index will be ignored.
Different from geneve, only one option can be set. And
also, geneve options, vxlan options or erspan options
can't be set at the same time.
# ip link add name erspan1 type erspan external
# tc qdisc add dev erspan1 ingress
# tc filter add dev erspan1 protocol ip parent ffff: \

enc_src_ip 10.0.99.192 \

v1->v2:

This patch is to allow matching gbp option in vxlan.
The options can be described in the form GBP/GBP_MASK,
where GBP is represented as a 32bit hexadecimal value.
Different from geneve, only one option can be set. And
also, geneve options and vxlan options can't be set at
the same time.

If rvu_get_blkaddr() fails, then this rvu_cgx_nix_cuml_stats() returns
zero and we write some uninitialized data into the debugfs output.
On the error paths, the use of the uninitialized "*stat" is harmless,
but it will lead to a Smatch warning (static analysis) and a UBSan
warning (runtime analysis) so we should prevent that as well.

fbdev uses the physical address of our framebuffer for its fb_mmap()
routine. While we need to adapt this address for the new io BAR, we have
to fix v5.4 first! The simplest fix is to restore the smem back to v5.3
and we will then probably have to implement our fbops->fb_mmap() callback
to handle local memory.

snprintf returns the number of chars that would be written, not number
of chars that were actually written. As such, 'offs' may get larger than
'tbl.maxlen', causing the 'tbl.maxlen - offs' being < 0, and since the
parameter is size_t, it would overflow.
Since using scnprintf may hide the limit error, while the buffer is still
enough now, let's just add a WARN_ON_ONCE in case it reach the limit
in future.
v2: Use WARN_ON_ONCE as Jiri and Eric suggested.

Currently collect_md gre tunnel will store the tunnel info(metadata_dst)
to skb_dst.
And now the non-tun-dst gre tunnel already can add tunnel header through
lwtunnel.
When received a arp_request on the non-tun-dst gre tunnel. The packet of
arp response will send through the non-tun-dst tunnel without tunnel info
which will lead the arp response packet to be dropped.
If the non-tun-dst gre tunnel also store the tunnel info as metadata_dst,
The arp response packet will set the releted tunnel info in the
iptunnel_metadata_reply.
The following is the test script:
ip netns add cl

Allow for audit messages to be emitted upon BPF program load and
unload for having a timeline of events. The load itself is in
syscall context, so additional info about the process initiating
the BPF prog creation can be logged and later directly correlated
to the unload event.
The only info really needed from BPF side is the globally unique
prog ID where then audit user space tooling can query / dump all
info needed about the specific BPF program right upon load event
and enrich the record, thus these changes needed here can be kept
small and non-intrusive to the core.
Raw example output:
# auditctl -D
# auditctl -a always,exit -F arch=x86_64 -S bpf
# ausearch --start recent -m 1334

Both rtl_work_func_t() and rtl8152_close() call napi_disable().
Since the two calls aren't protected by a lock, if the close
function starts executing before the work function, we can get into a
situation where the napi_disable() function is called twice in
succession (first by rtl8152_close(), then by set_carrier()).
In such a situation, the second call would loop indefinitely, since
rtl8152_close() doesn't call napi_enable() to clear the NAPI_STATE_SCHED
bit.
The rtl8152_close() function in turn issues a
cancel_delayed_work_sync(), and so it would wait indefinitely for the
rtl_work_func_t() to complete. Since rtl8152_close() is called by a
process holding rtnl_lock() which is requested by other processes, this
eventually leads to a system deadlock and crash.
Re-order the napi_disable() call to occur after the work function
disabling and urb cancellation calls are issued.

When receiving many or larger packets, e.g. when doing a file download,
it was observed that the read buffer size register reports up to 4 bytes
more than the current define allows in the check.
If this is the case, then no data transfer is initiated to receive the
packets (and thus to empty the buffer) which results in a stall of the
interface.
These 4 bytes are a hardware generated frame length which is prepended
to the actual frame, thus we have to respect it during our check.

Introduce the following parameters in order to add the possibility to sync
DMA memory for device before putting allocated pages in the page_pool
caches:
- PP_FLAG_DMA_SYNC_DEV: if set in page_pool_params flags, all pages that
the driver gets from page_pool will be DMA-synced-for-device according
to the length provided by the device driver. Please note DMA-sync-for-CPU
is still device driver responsibility
- offset: DMA address offset where the DMA engine starts copying rx data
- max_len: maximum DMA memory size page_pool is allowed to flush. This
is currently used in __page_pool_alloc_pages_slow routine when pages
are allocated from page allocator
These parameters are supposed to be set by device drivers.
This optimization reduces the length of the DMA-sync-for-device.
The optimization is valid because pages are initially
DMA-synced-for-device as defined via max_len. At RX time, the driver
will perform a DMA-sync-for-CPU on the memory for the packet length.
What is important is the memory occupied by packet payload, because
this is the area CPU is allowed to read and modify. As we don't track
cache-lines written into by the CPU, simply use the packet payload length
as dma_sync_size at page_pool recycle time. This also take into account
any tail-extend.

On some old Firmwares, connector type value was not supported, and value
read from FW was 0. For those, driver used link mode in order to set
connector type in link_ksetting.
After FW exposed the connector type, driver translated the value to ethtool
definitions. However, as 0 is a valid value, before returning PORT_OTHER,
driver run the check of link mode in order to maintain backward
compatibility.
Cited patch added support to EXT mode. With both features (connector type
and EXT link modes) ,if connector_type read from FW is 0 and EXT mode is
set, driver mistakenly compare EXT link modes to non-EXT link mode.
Fixed that by skipping this comparison if we are in EXT mode, as connector
type value is valid in this scenario.

When an ste hash table has too many collision we enlarge it
to a bigger hash table (rehash). Rehashing collision improvement
depends on the bytemask value. The more 1 bits we have in bytemask
means better spreading in the table.
Without this fix tables can grow in size without providing any
improvement which can lead to memory depletion and failures.
This patch will limit table rehash to reduce memory and improve
the performance.

The byte mask fields affect on the hash index distribution,
when the byte mask is zero, the hash calculation will always
be equal to the same index.
To avoid unneeded rehash of hash tables mark the table to skip
rehash.
This is needed by the next patch which will limit table rehash
to reduce memory consumption.

When creating a CQ, the CPU id is used for the vector value.
This would fail in-case the CPU id was higher than the maximum

Mirred action parsing code in parse_tc_fdb_actions() first checks if
out_dev has same parent id, and only verifies that there is a pending encap
action that was parsed before. Recent change in vxlan module made function
netdev_port_same_parent_id() to return true when called for mlx5 eswitch
representor and vxlan device created explicitly on mlx5 representor
device (vxlan devices created with "external" flag without explicitly
specifying parent interface are not affected). With call to
netdev_port_same_parent_id() returning true, incorrect code path is chosen
and encap rules fail to offload because vxlan dev is not a valid eswitch
forwarding dev. Dmesg log of error:
[ 1784.389797] devices ens1f0_0 vxlan1 not on same switch HW, can't offload forwarding
In order to fix the issue, rearrange conditional in parse_tc_fdb_actions()
to check for pending encap action before checking if out_dev has the same
parent id.

RFC 8033 suggests an alternative approach to calculate the queue
delay in PIE by using a timestamp on every enqueued packet. This
patch adds an implementation of that approach and sets it as the
default method to calculate queue delay. The previous method (based
on Little's law) to calculate queue delay is set as optional.
