When loading bnxt(4) driver, numerous warning are displayed (sysctl) as well as some failure (BAR0 mapping, IFDI_ATTACH_PRE) ~~~ sysctl_warn_reuse: can't re-use a leaf (dev.bnxt.0.%desc)! sysctl_warn_reuse: can't re-use a leaf (dev.bnxt.0.%driver)! sysctl_warn_reuse: can't re-use a leaf (dev.bnxt.0.%location)! sysctl_warn_reuse: can't re-use a leaf (dev.bnxt.0.%pnpinfo)! sysctl_warn_reuse: can't re-use a leaf (dev.bnxt.0.%parent)! sysctl_warn_reuse: can't re-use a leaf (dev.bnxt.0.%domain)! bnxt0: <Broadcom BCM57416 NetXtreme-E 10GBase-T Ethernet> mem 0xb8410000-0xb841ffff,0xb8300000-0xb83fffff,0xb8422000-0xb8423fff at device 0.0 numa-domain 0 on pci17 sysctl_warn_reuse: can't re-use a leaf (dev.bnxt.0.iflib.driver_version)! sysctl_warn_reuse: can't re-use a leaf (dev.bnxt.0.iflib.override_ntxqs)! sysctl_warn_reuse: can't re-use a leaf (dev.bnxt.0.iflib.override_nrxqs)! sysctl_warn_reuse: can't re-use a leaf (dev.bnxt.0.iflib.override_qs_enable)! sysctl_warn_reuse: can't re-use a leaf (dev.bnxt.0.iflib.disable_msix)! sysctl_warn_reuse: can't re-use a leaf (dev.bnxt.0.iflib.rx_budget)! sysctl_warn_reuse: can't re-use a leaf (dev.bnxt.0.iflib.tx_abdicate)! sysctl_warn_reuse: can't re-use a leaf (dev.bnxt.0.iflib.core_offset)! sysctl_warn_reuse: can't re-use a leaf (dev.bnxt.0.iflib.separate_txrx)! sysctl_warn_reuse: can't re-use a leaf (dev.bnxt.0.iflib.use_logical_cores)! sysctl_warn_reuse: can't re-use a leaf (dev.bnxt.0.iflib.override_ntxds)! sysctl_warn_reuse: can't re-use a leaf (dev.bnxt.0.iflib.override_nrxds)! bnxt0: PCI BAR0 mapping failure bnxt0: IFDI_ATTACH_PRE failed 6 device_attach: bnxt0 attach returned 6 pci0:72:0:0: Device leaked memory resources ~~~ Nevertheless the device seems to be working (I haven't try heavy load or complex configuration yet) Also perhaps related to the above errors, renaming interface in rc.conf using ifconfig_xxx_name, fails to have it's ip address configured later in rc.conf Failing example: ifconfig_bnxt0_name="net0" ifconfig_net0="inet aaa.bbb.ccc.ddd/24" But the following works ifconfig_bnxt0="inet aaa.bbb.ccc.ddd/24 name net0"
