Jacob Keller says:
====================
PCI: Implement function to read Device Serial Number
Several drivers read the Device Serial Number from the PCIe extended
configuration space. Each of these drivers implements a similar approach to
finding the position and then extracting the 8 bytes of data.
Implement a new helper function, pci_get_dsn, which can be used to extract
this data into an 8 byte array.
Modify the bnxt_en, qedf, ice, ixgbe and nfp drivers to use this new
function.
The intent for this is to reduce duplicate code across the various drivers,
and make it easier to write future code that wants to read the DSN. In
particular the ice driver will be using the DSN as its serial number when
implementing the DEVLINK_CMD_INFO_GET.
The new implementation in v2 significantly simplifies some of the callers
which just want to print the value out in MSB order. By returning things as
a u64 in CPU Endian order, the "%016llX" printf format specifier can be used
to correctly format the value.
Per patch changes since v1
PCI: Introduce pci_get_dsn
* Update commit message based on feedback from Bjorn Helgaas
* Modify the function to return a u64 (zero on no capability)
* This new implementation ensures that the first dword is the lower 32
bits and the second dword is the upper 32 bits.
bnxt_en: Use pci_get_dsn()
* Use the u64 return value from pci_get_dsn()
* Copy it into the dsn[] array by using put_unaligned_le64
* Fix a pre-existing typo in the netdev_info error message
scsi: qedf: Use pci_get_dsn()
* Use the u64 return value from pci_get_dsn()
* simplify the snprintf to use "%016llX"
* remove the unused 'i' variable
ice: Use pci_get_dsn()
* Use the u64 return value from pci_get_dsn()
* simplify the snprintf to use "%016llX"
ixgbe: Use pci_get_dsn()
* Use the u64 return value from pci_get_dsn()
* simplify the snprintf to use "%016llX"
nfp: Use pci_get_dsn()
* Added in v2

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

The original code used a for-loop that looped over each of the 8 bytes
and copied them into a temporary buffer. pci_get_dsn() uses two calls to
pci_read_config_dword, and correctly bitwise ORs them into a u64. Thus,
we can simplify the snprintf significantly using %016llX on a u64 value.

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.

When local NET_RX backlog is full due to traffic overrun,
peer veth tx_dropped counter increases. At that time, list
local veth stats, rx_dropped has double value of peer
tx_dropped, even bigger than transmit packets by peer.
In NET_RX softirq process, if any packet drop case happens,
it increases dev's rx_dropped counter and returns NET_RX_DROP.
At veth tx side, it records any error returned from peer netif_rx
into local dev tx_dropped counter.
In veth get stats process, it puts local dev rx_dropped and
peer dev tx_dropped into together as local rx_drpped value.
So that it shows double value of real dropped packets number in
this case.
This patch ignores peer tx_dropped when counting local rx_dropped,
since peer tx_dropped is duplicated to local rx_dropped at most cases.

HW generates a Data Size error for chacha20 requests that are not
a multiple of 64B, since algorithm state (AS) does not have
the FINAL bit set.
Since updating req->iv (for chaining) is not required,
modify skcipher descriptors to set the FINAL bit for chacha20.
[Note that for skcipher decryption we know that ctx1_iv_off is 0,
which allows for an optimization by not checking algorithm type,
since append_dec_op1() sets FINAL bit for all algorithms except AES.]
Also drop the descriptor operations that save the IV.
However, in order to keep code logic simple, things like
