Use an xdp_frame structure for managing the frame. Store a backpointer to
the structure at the start of the buffer before enqueueing for cleanup
on TX confirmation. Reserve DPAA_TX_PRIV_DATA_SIZE bytes from the frame
size shared with the XDP program for this purpose. Use the XDP
API for freeing the buffer when it returns to the driver on the TX
confirmation path.
The frame queues are shared with the netstack. The DPAA driver is a LLTX
driver so no explicit locking is required on transmission.
This approach will be reused for XDP REDIRECT.

Implement the XDP_DROP and XDP_PASS actions.
Avoid draining and reconfiguring the buffer pool at each XDP
setup/teardown by increasing the frame headroom and reserving
XDP_PACKET_HEADROOM bytes from the start. Since we always reserve an
entire page per buffer, this change only impacts Jumbo frame scenarios
where the maximum linear frame size is reduced by 256 bytes. Multi
buffer Scatter/Gather frames are now used instead in these scenarios.
Allow XDP programs to access the entire buffer.
The data in the received frame's headroom can be overwritten by the XDP
program. Extract the relevant fields from the headroom while they are
still available, before running the XDP program.
Since the headroom might be resized before the frame is passed up to the
stack, remove the check for a fixed headroom value when building an skb.
Allow the meta data to be updated and pass the information up the stack.
Scatter/Gather frames are dropped when XDP is enabled.

net: ipa: start adding IPA v4.5 support
This series starts updating the IPA code to support IPA hardware
version 4.5.
The first patch fixes a problem found while preparing these updates.
Testing shows the code works with or without the change, and with
the fix the code matches "downstream" Qualcomm code.
The second patch updates the definitions for IPA register offsets
and field masks to reflect the changes that come with IPA v4.5. A
few register updates have been deferred until later, because making
use of them involves some nontrivial code updates.
One type of change that IPA v4.5 brings is expanding the range of
certain configuration values. High-order bits are added in a few
cases, and the third patch implements the code changes necessary to
use those newly available bits.
The fourth patch implements several fairly minor changes to the code
required for IPA v4.5 support.
The last two patches implement changes to the GSI registers used for
IPA. Almost none of the registers change, but the range of memory
in which most of the GSI registers is located is shifted by a fixed
amount. The fifth patch updates the GSI register definitions, and
the last patch implements the memory shift for IPA v4.5.

The offsets for almost all GSI registers we use have different
offsets starting at IPA version 4.5. Only two registers remain
in their original location.
In a way though, the new register locations are not *that*
different. The entire group of affected registers has simply
been shifted down in memory by a fixed amount (0xd000). So for
example, the channel context 0 register that has a base offset of
0x0001c000 for "older" hardware now has a base offset of 0x0000f000.
This patch aims to add support for IPA v4.5 registers at their new
offets in a way that minimizes the amount of code that needs to
change. It is not ideal, but it avoids the need to maintain
a nearly complete set of additional register offset definitions.
The approach takes advantage of the fact that when accessing GSI
registers we do not access any of memory at lower end of the "gsi"
memory range (with two exceptions already noted). In particular,
we do not access anything within the bottom 0xd000 bytes of the
GSI memory range.
For IPA version 4.5, after we map the GSI memory, we adjust the
virtual memory pointer downward by the fixed amount (0xd000).
That way, register accesses using the offsets defined by the
existing GSI_REG_*() macros will resolve to the proper locations
for IPA version 4.5.
The two registers *not* affected by this offset are accessed only
in gsi_irq_setup(). There, for IPA version 4.5, we undo the general
register adjustment by adding the fixed amount back to the virtual
address to access these registers.

Update the IPA code to make use of the updated IPA v4.5 register
definitions. Generally what this patch does is, if IPA v4.5
hardware is in use:
- Ensure new registers or fields in IPA v4.5 are updated where
required
- Ensure registers or fields not supported in IPA v4.5 are not
examined when read, or are set to 0 when written
It does this while preserving the existing functionality for IPA
versions lower than v4.5.
The values to program for QSB_MAX_READS and QSB_MAX_WRITES and the
source and destination resource counts are updated to be correct for
all versions through v4.5 as well.
Note that IPA_RESOURCE_GROUP_SRC_MAX and IPA_RESOURCE_GROUP_DST_MAX
already reflect that 5 is an acceptable number of resources (which
IPA v4.5 implements).

IPA v4.5 adds a few fields to the endpoint header and extended
header configuration registers that represent new high-order bits
for certain offsets and sizes. Add code to incorporate these upper
bits into the registers for IPA v4.5.
This includes creating ipa_header_size_encoded(), which handles
encoding the metadata offset field for use in the ENDP_INIT_HDR
register in a way appropriate for the hardware version. This and
ipa_metadata_offset_encoded() ensure the mask argument passed to
u32_encode_bits() is constant.

Update "ipa_reg.h" so that register definitions support IPA hardware
version 4.5, in addition to versions 3.5.1 through v4.2. Most of
the register definitions are the same, but in some cases fields are
added, changed, or eliminated.
Updates for a few IPA v4.5 registers are more complex, and adding
those definition will be deferred to separate patches. This patch
only updates the register offset and field definitions, and adds
informational comments.
The only code change avoids accessing the backward compatibility
register for IPA version 4.5 in ipa_hardware_config(). Other IPA
v4.5-specific code changes will come later.

The 32-bit node number, aka node hash or node address, is calculated
based on the 128-bit node identity when it is not set explicitly by
the user. In future commits we will need to perform this hash operation
on peer nodes while feeling safe that we obtain the same result.
We do this by interpreting the initial hash as a network byte order
number. Whenever we need to use the number locally on a node
we must therefore translate it to host byte order to obtain an
architecure independent result.
Furthermore, given the context where we use this number, we must not
allow it to be zero unless the node identity also is zero. Hence, in
the rare cases when the xor-ed hash value may end up as zero we replace
it with a fix number, knowing that the code anyway is capable of
handling hash collisions.

mlxsw: Update adjacency index more efficiently
The device supports an operation that allows the driver to issue one
request to update the adjacency index for all the routes in a given
virtual router (VR) from old index and size to new ones. This is useful
in case the configuration of a certain nexthop group is updated and its
adjacency index changes.
Currently, the driver does not use this operation in an efficient
manner. It iterates over all the routes using the nexthop group and
issues an update request for the VR if it is not the same as the
previous VR.
Instead, this patch set tracks the VRs in which the nexthop group is
used and issues one request for each VR.
Example:
8k IPv6 routes were added in an alternating manner to two VRFs. All the
routes are using the same nexthop object ('nhid 1').

net/sched: fix over mtu packet of defrag in
Currently kernel tc subsystem can do conntrack in act_ct. But when several
fragment packets go through the act_ct, function tcf_ct_handle_fragments
will defrag the packets to a big one. But the last action will redirect
mirred to a device which maybe lead the reassembly big packet over the mtu
of target device.
The first patch fix miss init the qdisc_skb_cb->mru
The send one refactor the hanle of xmit in act_mirred and prepare for the
third one
The last one add implict packet fragment support to fix the over mtu for
defrag in act_ct.

Currently kernel tc subsystem can do conntrack in cat_ct. But when several
fragment packets go through the act_ct, function tcf_ct_handle_fragments
will defrag the packets to a big one. But the last action will redirect
mirred to a device which maybe lead the reassembly big packet over the mtu
of target device.
This patch add support for a xmit hook to mirred, that gets executed before
xmiting the packet. Then, when act_ct gets loaded, it configs that hook.
The frag xmit hook maybe reused by other modules.

The mru in the qdisc_skb_cb should be init as 0. Only defrag packets in the
act_ct will set the value.

Add CHACHA20-POLY1305 cipher to Kernel TLS
RFC 7905 defines usage of ChaCha20-Poly1305 in TLS connections. This
cipher is widely used nowadays and it's good to have a support for it
in TLS connections in kernel.
