[DPDK/bnxt] Issues starting bnxt on an Arm server

[Thierry Herbelot]

Hello Ajit

The card is not correctly probed by the kernel, and so the FW version is 
not visible.

I see this in the kernel dmesg:
bnxt_en 0000:03:00.0 (unnamed net_device) (uninitialized): Error 
(timeout: 500015) msg {0x0 0x0} len:0
bnxt_en 0000:03:00.0 (unnamed net_device) (uninitialized): Firmware not 
responding, status: 0x8ffff

And then there are no bnxt_en netdevices.

	Best regards

	Thierry
