To support loopback functionality between pairs NIX0/NIX1\nare attached to LBK1/LBK2 for transmission/reception respectively.\nBut in this default configuration NIX blocks cannot receive the\npackets they sent from the same LBK, which is an important requirement\nas some ODP applications only uses one AF VF for loopback functionality.\nTo support this scenario, NIX0 can use LBK0 (NIX1 - LBK3) by setting a\nloop flag while making LF alloc mailbox request.\n\nSigned-off-by: Harman Kalra <hkalra@marvell.com>\n---\n drivers/common/cnxk/roc_mbox.h | 1 +\n drivers/common/cnxk/roc_nix.c | 5 ++++-\n 2 files changed, 5 insertions(+), 1 deletion(-)", "diff": "diff --git a/drivers/common/cnxk/roc_mbox.h b/drivers/common/cnxk/roc_mbox.h\nindex b5da931b81..75d1ff1ef3 100644\n--- a/drivers/common/cnxk/roc_mbox.h\n+++ b/drivers/common/cnxk/roc_mbox.h\n@@ -723,6 +723,7 @@ struct nix_lf_alloc_req {\n \tuint64_t __io rx_cfg; /* See NIX_AF_LF(0..127)_RX_CFG */\n \tuint64_t __io way_mask;\n #define NIX_LF_RSS_TAG_LSB_AS_ADDER BIT_ULL(0)\n+#define NIX_LF_LBK_BLK_SEL\t BIT_ULL(1)\n \tuint64_t flags;\n };\n \ndiff --git a/drivers/common/cnxk/roc_nix.c b/drivers/common/cnxk/roc_nix.c\nindex 23d508b941..1621f77fb0 100644\n--- a/drivers/common/cnxk/roc_nix.c\n+++ b/drivers/common/cnxk/roc_nix.c\n@@ -145,9 +145,12 @@ roc_nix_lf_alloc(struct roc_nix *roc_nix, uint32_t nb_rxq, uint32_t nb_txq,\n \treq->npa_func = idev_npa_pffunc_get();\n \treq->sso_func = idev_sso_pffunc_get();\n \treq->rx_cfg = rx_cfg;\n+\tif (roc_nix_is_lbk(roc_nix) && roc_nix->enable_loop &&\n+\t roc_model_is_cn98xx())\n+\t\treq->flags = NIX_LF_LBK_BLK_SEL;\n \n \tif (!roc_nix->rss_tag_as_xor)\n-\t\treq->flags = NIX_LF_RSS_TAG_LSB_AS_ADDER;\n+\t\treq->flags |= NIX_LF_RSS_TAG_LSB_AS_ADDER;\n \n \trc = mbox_process_msg(mbox, (void *)&rsp);\n \tif (rc)\n", "prefixes": [ "1/2" ] }
