On debugging it looks like the change introduced as a part of th= is patch is causing the issue. https://patches.dpdk.org/patch/62140/ @@ -4135,6 +4138,10 @@ ixgbe_dev_link_update_share(struct rte_eth_dev *dev= , return rte_eth_linkstatus_set(dev, &link); } + esdp_reg =3D IXGBE_READ_REG(hw, IXGBE_ESDP); + if ((esdp_reg & IXGBE_ESDP_SDP3)) + link_up =3D 0; + if (link_up =3D=3D 0) { if (ixgbe_get_media_type(hw) =3D=3D ixgbe_media_type_fiber) { intr->flags |=3D IXGBE_FLAG_NEED_LINK_CONFIG; I can see that the esdp_req is coming as 3735928495(0xDEADBEAF) and due to = which the link_up is set to 0 even when ixgbevf_check_link returned link_up= as 1. Along with this patch I also see a path_fullchk patch introduced , d= oes that play any role in this ? Can someone please let me know if the patch has got some issues or it is be= having correctly and the link_status is failing for valid reason. As mentio= ned earlier the same HW with same NIC acting in SR-IOV works fine with 18.1= 1.2 DPDK . I am blocked at a customer bug dew to this and any urgent help w= ill be much appreciated. -- Regards, Souvik ---------------------------------------------------------------------------= -------------------------------------------- Notice: This e-mail together with any attachments may contain information o= f Ribbon Communications Inc. that is confidential and/or proprietary for the sole use of the intended recipie= nt.
