Add interface to a "bnx2x:QLogic 5771x/578xx"-card?

The kernel seems to recognize the networkcard
bnx2x: QLogic 5771x/578xx 10/20-Gigabit Ethernet Driver bnx2x 1.713.36-0 (2014/02/10)

But it does not assign a ethx to either of the ports, as it does with my other networkcards (igb 4 port & e1000e internal).

Linux Home 5.4.81 #0 SMP Mon Dec 7 13:22:00 2020 x86_64 GNU/Linux

Any advice?
Thanks in advance.

ifconfig show what ? i have those cards copper and fiber and both worked fine with openwrt and pfsense

same issue.
openwrt kernel version 5.4.101
BCM57810S 10G SPF+ card (PCI-E slot)
proxmox has been passthough successfully and signed to openwrt(VM), but in openwrt it failed to load, even not loaded by kernel.
the driver version: bnx2x-firmware_20201118-3_x86_64.ipk and kmod-bnx2x_5.4.105-1_x86_64.ipk
