- Rephrase wording such that the file flows better
- Improve consistency with respect to word use, grammar and style
- Remove point on loops not being supported as BPF now has support for
  bounded loops

selftests/bpf: Test bpf_mprog query API via libbpf and raw syscall
f255aca 
Add a new test case which performs double query of the bpf_mprog through
libbpf API, but also via raw bpf(2) syscall. This is testing to gather
first the count and then in a subsequent probe the full information with
the program array without clearing passed structs in between.

selftests/bpf: Test bpf_mprog query API via libbpf and raw syscall
f9b0879 
Add a new test case which performs double query of the bpf_mprog through
libbpf API, but also via raw bpf(2) syscall. This is testing to gather
first the count and then in a subsequent probe the full information with
the program array without clearing passed structs in between.

rx_create no longer allocates a modify_hdr instance that needs to be

dereference. A leak in the rules also previously occurred since there are
now two rules populated related to status.

net/mlx5: Use mlx5_ipsec_rx_status_destroy to correctly delete status…
5e1669d 
… rules

rx_create no longer allocates a modify_hdr instance that needs to be
cleaned up. The mlx5_modify_header_dealloc call will lead to a NULL pointer
dereference. A leak in the rules also previously occurred since there are
now two rules populated related to status.
