[ Upstream commit dd1979cf3c710398a9eeba4853b908fe16426814 ]
PTP-RQ counters title format contains PTP-RQ identifier, which is mistakenly not passed to sprinft(). This leads to unexpected garbage values instead. This patch fixes it.
Before applying the patch: ethtool -S eth3 | grep ptp_rq ptp_rq15_packets: 0 ptp_rq8_bytes: 0 ptp_rq6_csum_complete: 0 ptp_rq14_csum_complete_tail: 0 ptp_rq3_csum_complete_tail_slow : 0 ptp_rq9_csum_unnecessary: 0 ptp_rq1_csum_unnecessary_inner: 0 ptp_rq7_csum_none: 0 ptp_rq10_xdp_drop: 0 ptp_rq9_xdp_redirect: 0 ptp_rq13_lro_packets: 0 ptp_rq12_lro_bytes: 0 ptp_rq10_ecn_mark: 0 ptp_rq9_removed_vlan_packets: 0 ptp_rq5_wqe_err: 0 ptp_rq8_mpwqe_filler_cqes: 0 ptp_rq2_mpwqe_filler_strides: 0 ptp_rq5_oversize_pkts_sw_drop: 0 ptp_rq6_buff_alloc_err: 0 ptp_rq15_cqe_compress_blks: 0 ptp_rq2_cqe_compress_pkts: 0 ptp_rq2_cache_reuse: 0 ptp_rq12_cache_full: 0 ptp_rq11_cache_empty: 256 ptp_rq12_cache_busy: 0 ptp_rq11_cache_waive: 0 ptp_rq12_congst_umr: 0 ptp_rq11_arfs_err: 0 ptp_rq9_recover: 0
