Finally had more time (what with Covid-19) for this;
Checked dmesg which states
[ 7.668835] bnx2 0000:05:00.0 eth0: Broadcom NetXtreme II BCM5716 1000Base-T (C0) PCI Express found at mem da000000, IRQ 16, node addr 00:26:b9:86:11:1e
[ 7.803026] bnx2 0000:05:00.1 eth1: Broadcom NetXtreme II BCM5716 1000Base-T (C0) PCI Express found at mem dc000000, IRQ 17, node addr 00:26:b9:86:11:1f
.
.
"Direct firmware load for bnx2/bnx2-mips-09-6.2.1b.fw failed with error -2
Can't load firmware file "bnx2/bnx2-mips-09-6.2.1b.fw"
"
The firmware file is supplied from another linux install with same kernel version and is in /storage/.config/firmware
So I downloaded all files for a kernel build and checked the linux.x86_64.conf and found the entry for "BNX2=y"
so I'm stumped as to issue as the machine works fine with Ubuntu 18.04 server

anyone got a clue here?
