Ethernet not working on a different SoC with same eth HW

[Mason <slash.tmp@free.fr>]

Hello everyone,

I'm using these net drivers:

  drivers/net/ethernet/aurora/nb8800.c
  drivers/net/phy/at803x.c

With a smp8758 board, they work great.
I've been trying to use them on a different board:

  same eth PHY (Atheros AR8035)
  same eth MAC (Aurora SSN8800)
  different SoC (same base address for MAC block)

It doesn't work, and I'm not sure where to look first...
I put logs in some functions to get a rough idea.
When the kernel boots, it prints:

which looks alright, I suppose.

Then I configure the address, and set link up:

ip addr add 10.10.7.81/24 dev eth0
ip link set eth0 up
