I get this when the system boots and the interface is not there in an 
"ifconfig":

mlx4_core0: <mlx4_core> mem 0xa2300000-0xa23fffff,0xa2800000-0xa2ffffff 
irq 17 a
t device 0.0 on pci2
mlx4_core: Mellanox ConnectX core driver v3.7.1 (November 2021)
mlx4_core: Initializing 0000:02:00.0
mlx4_core0: Unable to determine PCI device chain minimum BW

If I kldunload the driver it immediately reloads with:

pci2: <network, ethernet> at device 0.0 (no driver attached)
mlx4_core0: <mlx4_core> mem 0xa2300000-0xa23fffff,0xa2800000-0xa2ffffff 
irq 17 at device 0.0 on pci2
mlx4_core: Mellanox ConnectX core driver v3.7.1 (November 2021)
mlx4_core: Initializing 0000:02:00.0
mlx4_core0: Unable to determine PCI device chain minimum BW

At present I do not have the other end connected to anything (I have a 
short-distance direct-wire SPF+ cable from Mellanox that I intend to 
plug into the switch in the same rack) but I wouldn't expect that to 
impact the driver being unable to come up.

Do I have a card that FreeBSD does not support and have drivers for 
(although at first blush it appears it does find it)?  The Nvidia 
documentation page has a link to an older driver intended for FreeBSD 
10.1 (it doesn't resolve and neither do the release note or user manual 
links)

Thanks in advance!
