Similar to RISC-V, the current version for LoongArch do not support
vector. Re-use vector processing stubs in ixgbe PMD defined for PPC
for LoongArch. This enables ixgbe PMD usage in scalar mode on
LoongArch.

The ixgbe PMD driver was validated with Intel X520-DA2 NIC and the
test-pmd application, l2fwd, l3fwd examples.
