Ping, this migt be causing issue when using the mlx4 driver today. Ubuntu 16.04 Xenial 4.4.0-116-generic #140-Ubuntu SMP Mon Feb 12 21:23:04 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux
The following file is no longer needed, mlx4_core and mlx4_en will be loaded properly automatic cat /etc/modprobe.d/mlx4.conf # mlx4_core should load mlx4_en (LP: #1115710). softdep mlx4_core post: mlx4_en Another issue I have, I cannot enable VXLAN offloading on boot. I have tried: * Keeping /etc/modprobe.d/mlx4.conf and adding "options mlx4_core log_num_mgm_entry_size=-1" to start of file * Keeping /etc/modprobe.d/mlx4.conf and adding "options mlx4_core log_num_mgm_entry_size=-1" to end of file * Remove all lines in /etc/modprobe.d/mlx4.conf except for "options mlx4_core log_num_mgm_entry_size=-1" * Keeping /etc/modprobe.d/mlx4.conf and adding "options mlx4_core log_num_mgm_entry_size=-1" to /etc/modprobe.d/mlx4_core.conf * Removing /etc/modprobe.d/mlx4.conf and adding "options mlx4_core log_num_mgm_entry_size=-1" to /etc/modprobe.d/mlx4_core.conf None of these makes the VXLAN offloading capability available. ethtool -k enp59s0 | grep tx-udp tx-udp_tnl-segmentation: off [fixed] But if I remove and load the driver manually after boot and add it again to works. modprobe -r mlx4_en modprobe -r mlx4_core (after I load modules manually below I also get the mlx4_ib module, so the process to remove again involves unloading mlx4_en and mlx4_ib before unloading mlx4_core) * Keeping /etc/modprobe.d/mlx4.conf and adding "options mlx4_core log_num_mgm_entry_size=-1" to start of file modprobe mlx4_en ethtool -k enp59s0 | grep tx-udp tx-udp_tnl-segmentation: on * Keeping /etc/modprobe.d/mlx4.conf and adding "options mlx4_core log_num_mgm_entry_size=-1" to end of file modprobe mlx4_en ethtool -k enp59s0 | grep tx-udp tx-udp_tnl-segmentation: on * Remove all lines in /etc/modprobe.d/mlx4.conf except for "options mlx4_core log_num_mgm_entry_size=-1" modprobe mlx4_en ethtool -k enp59s0 | grep tx-udp tx-udp_tnl-segmentation: on * Removing /etc/modprobe.d/mlx4.conf and adding "options mlx4_core log_num_mgm_entry_size=-1" to /etc/modprobe.d/mlx4_core.conf modprobe mlx4_en ethtool -k enp59s0 | grep tx-udp tx-udp_tnl-segmentation: on On boot the following modules is loaded: # lsmod | grep mlx mlx4_en 110592 0 vxlan 49152 2 i40e,mlx4_en mlx4_core 286720 1 mlx4_en ptp 20480 3 igb,i40e,mlx4_en When I modprobe manually the following modules is loaded: # lsmod | grep mlx mlx4_ib 151552 0 mlx4_en 110592 0 mlx4_core 286720 2 mlx4_en,mlx4_ib ib_sa 36864 3 rdma_cm,ib_cm,mlx4_ib ib_mad 49152 3 ib_cm,ib_sa,mlx4_ib ib_core 106496 7 rdma_cm,ib_cm,ib_sa,iw_cm,mlx4_ib,ib_mad,ib_iser vxlan 49152 2 i40e,mlx4_en ptp 20480 3 igb,i40e,mlx4_en What could cause this blockage that the driver is not loaded properly with the options on boot?
