PAM4 signaling will be\nused only for 200G speed negotiations.\n\nDriver has to check for NRZ speed support first while forcing speed.\n\nFixes: c23f9ded0391 (\"net/bnxt: support 200G PAM4 link\")\nCc: stable@dpdk.org\n\nSigned-off-by: Kalesh AP <kalesh-anakkur.purayil@broadcom.com>\nReviewed-by: Somnath Kotur <somnath.kotur@broadcom.com>\nReviewed-by: Ajit Khaparde <ajit.khaparde@broadcom.com>\n---\n drivers/net/bnxt/bnxt_hwrm.c | 22 ++++++++++++----------\n 1 file changed, 12 insertions(+), 10 deletions(-)",
