XDP bulk APIs introduce a defer/flush mechanism to return
pages belonging to the same xdp_mem_allocator object
(identified via the mem.id field) in bulk to optimize
I-cache and D-cache since xdp_return_frame is usually run
inside the driver NAPI tx completion loop.
The bulk queue size is set to 16 to be aligned to how
XDP_REDIRECT bulking works. The bulk is flushed when
it is full or when mem.id changes.
xdp_frame_bulk is usually stored/allocated on the function
call-stack to avoid locking penalties.
Current implementation considers only page_pool memory model.

We can simplify the for() condition and eliminate variable tx_left.
The change also considers that tp->cur_tx may be incremented by a
racing rtl8169_start_xmit().
In addition replace the write to tp->dirty_tx and the following
smp_mb() with an equivalent call to smp_store_mb(). This implicitly
adds a WRITE_ONCE() to the write.

The IPA-resident microcontroller has the ability to log various
activity in an area of IPA shared memory. When the microcontroller
starts it generates an event to the AP to provide information about
the log.
We don't support reading this log, and we can safely ignore the
event. So do that rather than treating the log info event we
receive as "unsupported."

We can treat SKB_GSO_GRE almost exactly the same as UDP tunnels, except

Sleepable hooks are never called from an NMI/interrupt context, so it
is safe to use the bpf_d_path helper in LSM programs attaching to these

This patch tests storing the task's related info into the
bpf_sk_storage by fentry/fexit tracing at listen, accept,
and connect. It also tests the raw_tp at inet_sock_set_state.
A negative test is done by tracing the bpf_sk_storage_free()
and using bpf_sk_storage_get() at the same time. It ensures
this bpf program cannot load.

This patch enables the FENTRY/FEXIT/RAW_TP tracing program to use
the bpf_sk_storage_(get|delete) helper, so those tracing programs
can access the sk's bpf_local_storage and the later selftest
will show some examples.
The bpf_sk_storage is currently used in bpf-tcp-cc, tc,
cg sockops...etc which is running either in softirq or
task context.
This patch adds bpf_sk_storage_get_tracing_proto and
bpf_sk_storage_delete_tracing_proto. They will check
in runtime that the helpers can only be called when serving
softirq or running in a task context. That should enable
most common tracing use cases on sk.
During the load time, the new tracing_allowed() function
will ensure the tracing prog using the bpf_sk_storage_(get|delete)
helper is not tracing any bpf_sk_storage*() function itself.
The sk is passed as "void *" when calling into bpf_local_storage.
This patch only allows tracing a kernel function.

This patch adds the verifier support to recognize inlined branch conditions.
The LLVM knows that the branch evaluates to the same value, but the verifier
couldn't track it. Hence causing valid programs to be rejected.
The potential LLVM workaround: https://reviews.llvm.org/D87428
can have undesired side effects, since LLVM doesn't know that
skb->data/data_end are being compared. LLVM has to introduce extra boolean
variable and use inline_asm trick to force easier for the verifier assembly.
Instead teach the verifier to recognize that
r1 = skb->data;
r1 += 10;
r2 = skb->data_end;
if (r1 > r2) {
here r1 points beyond packet_end and
subsequent
if (r1 > r2) // always evaluates to "true".

__mlxsw_sp_router_set_abort_trap()
Don't pass RALXX register enum and rather pass enum mlxsw_sp_l3proto
to __mlxsw_sp_router_set_abort_trap(). This is in preparation to fib
entry pack implementation by XMDR register.

Use netdev->tstats instead of a member of usbnet for storing a pointer
to the per-cpu counters. This allows us to use core functionality for
statistics handling.

Use netdev->tstats instead of a member of qtnf_vif for storing a pointer
to the per-cpu counters. This allows us to use core functionality for
statistics handling.
The driver sets netdev->needs_free_netdev, therefore freeing the per-cpu
counters at the right point in time is a little bit tricky. Best option
seems to be to use the ndo_init/ndo_uninit callbacks.
