https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D237166 --- Comment #1 from ncrogers@gmail.com --- Here's what happens when trying to explicitly indicate number of descriptors for each queue... In general whatever is set in loader.conf for override_nrxds/txds, the resulting sysctl output has an additional ",0" appended to it for vmx1, but not vmx0. test# grep vmx /boot/loader.conf dev.vmx.0.iflib.override_ntxds=3D4096,4096 dev.vmx.0.iflib.override_nrxds=3D2048,2048 dev.vmx.1.iflib.override_ntxds=3D4096 dev.vmx.1.iflib.override_nrxds=3D2048 dev.vmx.0.iflib.override_ntxqs=3D2 dev.vmx.0.iflib.override_nrxqs=3D2 dev.vmx.1.iflib.override_ntxqs=3D2 dev.vmx.1.iflib.override_nrxqs=3D2 test# sysctl -a | grep override dev.vmx.1.iflib.override_nrxds: 2048,0,0 dev.vmx.1.iflib.override_ntxds: 4096,0 dev.vmx.1.iflib.override_qs_enable: 0 dev.vmx.1.iflib.override_nrxqs: 2 dev.vmx.1.iflib.override_ntxqs: 2 dev.vmx.0.iflib.override_nrxds: 0,0,0 dev.vmx.0.iflib.override_ntxds: 0,0 dev.vmx.0.iflib.override_qs_enable: 0 dev.vmx.0.iflib.override_nrxqs: 2 dev.vmx.0.iflib.override_ntxqs: 2 test# grep vmx /var/run/dmesg.boot=20 vmx0: <VMware VMXNET3 Ethernet Adapter> port 0x4000-0x400f mem 0xfea03000-0xfea03fff,0xfea02000-0xfea02fff,0xfea00000-0xfea01fff at device= 0.0 on pci3 vmx0: Using 512 tx descriptors and 256 rx descriptors vmx0: Using 2 rx queues 2 tx queues vmx0: Using MSI-X interrupts with 3 vectors vmx0: Ethernet address: 00:0c:29:2b:73:76 vmx0: netmap queues/slots: TX 2/512, RX 2/512 vmx1: <VMware VMXNET3 Ethernet Adapter> port 0x3000-0x300f mem 0xfe203000-0xfe203fff,0xfe202000-0xfe202fff,0xfe200000-0xfe201fff at device= 0.0 on pci4 vmx1: Using 512 tx descriptors and 256 rx descriptors vmx1: Using 2 rx queues 2 tx queues vmx1: Using MSI-X interrupts with 3 vectors vmx1: Ethernet address: 00:0c:29:2b:73:80 vmx1: netmap queues/slots: TX 2/512, RX 2/512 vmx0: link state changed to UP vmx1: link state changed to UP test# --=20 You are receiving this mail because: You are the assignee for the bug.=
