Stanislav Fomichev d5e726d914 xsk: Require XDP_UMEM_TX_METADATA_LEN to actuate tx_metadata_len ... Julian reports that commit 341ac980ea ("xsk: Support tx_metadata_len") can break existing use cases which don't zero-initialize xdp_umem_reg padding. Introduce new XDP_UMEM_TX_METADATA_LEN to make sure we interpret the padding as tx_metadata_len only when being explicitly asked.
