netfilter: nft_set_hash: fix get operation on big endian

Browse source

[ Upstream commit 2f635adbe2 ]

tests/shell/testcases/packetpath/set_match_nomatch_hash_fast
fails on big endian with:

Error: Could not process rule: No such file or directory
reset element ip test s { 244.147.90.126 }
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Fatal: Cannot fetch element "244.147.90.126"

... because the wrong bucket is searched, jhash() and jhash1_word are
not interchangeable on big endian.
