I tested it using netdevsim/veth and my Broadcom NIC.
It appears that netdevsim/veth has no issues, but I encountered many
RTNL assertions in the bnxt driver.
Reproducer:
interface=<bnxt interface>
ip a a 10.0.0.1/24 dev $interface
ip a a 2001:db8::1/64 dev $interface
ip link set $interface up
reboot

Sorry for the too-long splats.
I didn't see all splats, but I think the cause is only one,
netdev_lock()+netif_close() path. please look at bnxt_shutdown().
The commits 110eff172dfe ("eth: bnxt: switch to netif_close") and
004b5008016a ("eth: bnxt: remove most dependencies on RTNL")
replace rtnl_lock() + dev_close() to netdev_lock() + netif_close().
However, internal functions of netif_close() are still using
rtnl_dereference(). So, there are many RTNL assertions on the
netif_close() path.
Only the bnxt driver uses netif_close(), so other drivers don't have
this problem.
Could you please look into this?
Thanks a lot!
