- mark tcb state to close in tls_dev_del.
- u_ctx is now picked from adapter structure.
- clear atid in case of failure.
- corrected ULP_CRYPTO_KTLS_INLINE value.
v2->v3:
- add empty line after variable declaration.
- local variable declaration in reverse christmas tree ordering.

Align buffers, data start, SG fragment length to avoid DMA splits.
These changes prevent the A050385 erratum to manifest itself:
FMAN DMA read or writes under heavy traffic load may cause FMAN
internal resource leak; thus stopping further packet processing.
The FMAN internal queue can overflow when FMAN splits single
read or write transactions into multiple smaller transactions
such that more than 17 AXI transactions are in flight from FMAN
to interconnect. When the FMAN internal queue overflows, it can
stall further packet processing. The issue can occur with any one
of the following three conditions:
1. FMAN AXI transaction crosses 4K address boundary (Errata
A010022)
2. FMAN DMA address for an AXI transaction is not 16 byte
aligned, i.e. the last 4 bits of an address are non-zero
3. Scatter Gather (SG) frames have more than one SG buffer in
the SG list and any one of the buffers, except the last
buffer in the SG list has data size that is not a multiple
of 16 bytes, i.e., other than 16, 32, 48, 64, etc.
With any one of the above three conditions present, there is
likelihood of stalled FMAN packet processing, especially under
stress with multiple ports injecting line-rate traffic.
To avoid situations that stall FMAN packet processing, all of the
above three conditions must be avoided; therefore, configure the
system with the following rules:
1. Frame buffers must not span a 4KB address boundary, unless
the frame start address is 256 byte aligned
2. All FMAN DMA start addresses (for example, BMAN buffer
address, FD[address] + FD[offset]) are 16B aligned
3. SG table and buffer addresses are 16B aligned and the size
of SG buffers are multiple of 16 bytes, except for the last
SG buffer that can be of any size.
Additional workaround notes:
- Address alignment of 64 bytes is recommended for maximally
efficient system bus transactions (although 16 byte alignment is
sufficient to avoid the stall condition)
- To support frame sizes that are larger than 4K bytes, there are
two options:
1. Large single buffer frames that span a 4KB page boundary can
be converted into SG frames to avoid transaction splits at
the 4KB boundary,
2. Align the large single buffer to 256B address boundaries,
ensure that the frame address plus offset is 256B aligned.
- If software generated SG frames have buffers that are unaligned
and with random non-multiple of 16 byte lengths, before
transmitting such frames via FMAN, frames will need to be copied
into a new single buffer or multiple buffer SG frame that is
compliant with the three rules listed above.

Use the newly added pci_get_dsn() function for obtaining the 64-bit
Device Serial Number in the nfp6000_read_serial and
nfp_6000_get_interface functions.
pci_get_dsn() reports the Device Serial number as a u64 value created by
combining two pci_read_config_dword functions. The lower 16 bits
represent the device interface value, and the next 48 bits represent the
serial value. Use put_unaligned_be32 and put_unaligned_be16 to convert
the serial value portion into a Big Endian formatted serial u8 array.

Replace the open-coded implementation for reading the PCIe DSN with
pci_get_dsn().
The original code used a simple for-loop to read the bytes in order into
a buffer one byte at a time.
The pci_get_dsn() function returns the DSN as a u64, correctly ordering
the upper and lower 32 bit dwords. Simplify the display code by using
%016llX to display the u64 DSN.
This should have equivalent behavior on both Little and Big Endian
systems. The bus will have correctly ordered the dwords in the CPU
endian format, while pci_get_dsn() will correctly order the lower and
higher dwords into a u64.

Replace the open-coded implementation for reading the PCIe DSN with
pci_get_dsn().
The pci_get_dsn() function will perform two pci_read_config_dword calls
to read the lower and upper config dwords. It bitwise ORs them into
a u64 value. Instead of using put_unaligned_le32 to convert the value to
LE32 format, just use the %016llX printf specifier. This will print the
u64 correct, putting the most significant byte of the value first. Since
pci_get_dsn() correctly orders the two dwords into a u64, this should
produce equivalent results in less code.

Replace the open-coded implementation for reading the PCIe DSN with
pci_get_dsn().
Use of put_unaligned_le64 should be correct. pci_get_dsn() will perform
two pci_read_config_dword calls. The first dword will be placed in the
first 32 bits of the u64, while the second dword will be placed in the
upper 32 bits of the u64.
On Little Endian systems, the least significant byte comes first, which
will be the least significant byte of the first dword, followed by the
least significant byte of the second dword. Since the _le32 variations
do not perform byte swapping, we will correctly copy the dwords into the
dsn[] array in the same order as before.
On Big Endian systems, the most significant byte of the second dword
will come first. put_unaligned_le64 will perform a CPU_TO_LE64, which
will swap things correctly before copying. This should also end up with
the correct bytes in the dsn[] array.
While at it, fix a small typo in the netdev_info error message when the
DSN cannot be read.

We now ignore the "completion" event when using tx queue timestamping,
and only pay attention to the two (high and low) timestamp events. The
NIC will send a pair of timestamp events for every packet transmitted.
The current firmware may merge the completion events, and it is possible
that future versions may reorder the completion and timestamp events.
As such the completion event is not useful.
Without this patch in place a merged completion event on a queue with
timestamping will cause a "spurious TX completion" error. This affects
SFN8000-series adapters.

The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:
struct foo {
int stuff;
struct boo array[];
};
By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.
Also, notice that, dynamic memory allocations won't be affected by
this change:
"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]
This issue was found with the help of Coccinelle.

There are two peculiarities about offloading FIFO:
- sometimes the qdisc has an unspecified handle (it is "invisible")
- it may be created before the qdisc that it will be a child of
These features make the offload a bit more tricky. The approach chosen in
this patch is to make note of all the FIFOs that needed to be rejected
because their parents were not known. Later when the parent is created,
they are offloaded
FIFO is only offloaded for its counters, queue length is ignored.

When fibre port supports auto-negotiation, the IMP(Intelligent
Management Process) processes the speed of auto-negotiation
and the user's speed separately.
For below case, the port will get a not link up problem.
step 1: disables auto-negotiation and sets speed to A, then
the driver's MAC speed will be updated to A.
step 2: enables auto-negotiation and MAC gets negotiated
speed B, then the driver's MAC speed will be updated to B
through querying in periodical task.
step 3: MAC gets new negotiated speed A.
step 4: disables auto-negotiation and sets speed to B before
periodical task query new MAC speed A, the driver will ignore
the speed configuration.
This patch fixes it by skipping speed and duplex checking when
fibre port supports auto-negotiation.

Expose raw packet pacing APIs to be used by DEVX based applications.
The existing code was refactored to have a single flow with the new raw
APIs.
The new raw APIs considered the input of 'pp_rate_limit_context', uid,
'dedicated', upon looking for an existing entry.
This raw mode enables future device specification data in the raw
context without changing the existing logic and code.
The ability to ask for a dedicated entry gives control for application
to allocate entries according to its needs.
A dedicated entry may not be used by some other process and it also
enables the process spreading its resources to some different entries
for use different hardware resources as part of enforcing the rate.
The counter per entry was changed to be u64 to prevent any option to
overflow.
