This patch introduce a redundancy flow action to implement frame

IEEE P802.1CB.
There are two modes for redundancy action: generator and recover mode.
Generator mode add redundancy tag and replicate the frame to different

Since NCI 2.0, CORE_RESET and CORE_INIT sequence have been changed.
If NFCEE supports NCI 2.x, then NCI 2.x initial sequence will work.
In NCI 1.0, Initial sequence and payloads are as below:

In the absolute majority of cases if a process is making a kernel
allocation, it's memory cgroup is getting charged.
Bpf maps can be updated from an interrupt context and in such
case there is no process which can be charged. It makes the memory
accounting of bpf maps non-trivial.
Fortunately, af
Do not use rlimit-based memory accounting for bpf ringbuffer.
It has been replaced with the memcg-based memory accounting.
bpf_ringbuf_alloc() can't return anything except ERR_PTR(-ENOMEM)
and a valid pointer, so to simplify the code make it return NULL
in the first case. This allows to drop a cou
This patch enables memcg-based memory accounting for memory allocated
by __bpf_map_area_alloc(), which is used by many types of bpf maps for
large memory allocations.
Following patches in the series will refine the accounting for
some of the map types.

Since bpf is not using rlimit memlock for the memory accounting
and control, do not change the limit in sample applications.
