    "content": "From: Venkat Duvvuru <venkatkumar.duvvuru@broadcom.com>\n\nbp->rx_num_qs_per_vnic is not initialized in the single queue mode.\nAs a result of this when an interface is reconfigured to single\nqueue mode from an existing multiqueue mode, bp->rx_num_qs_per_vnic\nis not updated to the value of 1. Hence, the driver will try to\naccess more than one queue resulting in a crash.\n\nThis patch fixes it by initializing bp->rx_num_qs_per_vnic in the\nsingle queue mode as well.\n\nFixes: 36024b2e7fe5 (\"net/bnxt: allow dynamic creation of VNIC\")\nCc: stable@dpdk.org\n\nSigned-off-by: Venkat Duvvuru <venkatkumar.duvvuru@broadcom.com>\nReviewed-by: Somnath Kotur <somnath.kotur@broadcom.com>\nReviewed-by: Kalesh AP <kalesh-anakkur.purayil@broadcom.com>\nReviewed-by: Ajit Kumar Khaparde <ajit.khaparde@broadcom.com>\n---\n drivers/net/bnxt/bnxt_rxq.c | 3 ++-\n 1 file changed, 2 insertions(+), 1 deletion(-)",
