[PATCH v3 07/14] test/bpf: fix unsupported BPF instructions in ELF load test

[Stephen Hemminger <stephen@networkplumber.org>]

The DPDK BPF library only handles the base BPF instructions.
It does not handle JMP32 which would cause the bpf_elf_load
test to fail on clang 20 or later.

Bugzilla ID: 1844
Fixes: cf1e03f881af ("test/bpf: add ELF loading")
Cc: stable@dpdk.org
