This patch series adds support for the RISC-V Vector (V) extension and provides
an optimized implementation of `rte_lpm_lookupx4` using RVV. It includes runtime
detection of the V extension, conditional compilation based on compiler support
for RVV intrinsics.
Test results using lpm_perf_autotest on BPI-F3:
scalar: 5.7 cycles
rvv: 2.4 cycles
### v2:
- Improved commit messages.
sunyuechi (3):
config/riscv: detect V extension
lib/lpm: R-V V rte_lpm_lookupx4
riscv: override machine_args only when default
