Decode each eight-byte chunk with be64dec() into the register-word array before programming the five key registers. This matches the key serialization in DPDK's nicvf_rss_set_key(), added by commit 7694fab264ac666d62a4cae04f2979991ce64259 ("net/thunderx/base: add RSS and RETA configuration"). A raw copy into the word array on little-endian hosts would reverse bytes within each register relative to that convention. Preserve the CPI-algorithm gate, enabled hash fields, and round-robin indirection table.
