I have a VM backed by vCenter. vCenter ESXi have physical adapter "Broadcom BCM57414 NetXtreme-E 10Gb/25Gb RDMA Ethernet Controller" and SR-IOV enabled on this.
VM is connected to 1mgmt network (vmxnet3) and 2 SR-IOV adapters (SRIOVPassthrough).
Upon booting of the VM, only 2 networks shown up. (1mgmt and 1SR-IOV).
Journalctl -k logs showed following error.
[ 4832.408471] bnxt_en 0000:13:00.0 (unnamed net_device) (uninitialized): Error (timeout: 500015) msg {0x0 0x0} len:0
[ 4832.408930] bnxt_en: probe of 0000:13:00.0 failed with error -1
Reboot of machine did not help at all.
For the successful one adapter
bnxt_en 0000:03:00.0 eth1: NIC Link is Up, 25000 Mbps full duplex, Flow control: ON - receive & transmit
bnxt_en 0000:03:00.0 eth1: FEC autoneg off encodings: None
I did rescan of the pci devices and did multiple times reboot without any success.
Any pointers would be really helpful
Disabling PXE didn't work for us, but we can get the ports back online, by running
echo 0000:af:00.0 > /sys/bus/pci/drivers/bnxt_en/bind
Where
0000:af:00.0
is the PCI number for the port, which can be gotten fromdmesg | grep bnxt_en
and looking for the port or ports that failed.
