Starting from AA when ramips support was added we get failsafe mode issue.
Digging the problem I suggest:
1. Change switch init: if vlan disabled set pvid 1 for all ports and add
all ports
into vlan0 with vid=1
2. Change init order in ethernet driver probe - init ESW after FE.
First step allow to set eth0 in predictable state after ethernet
driver init'ed or at any time with simple:
swconfig dev switch0 set reset 1
Second step is needed because some SOCs (rt5350,rt3352) reset FE and ESW
together
during ethernet probe but I think only for AA.
All these allow simplify ramips_set_preinit_iface() to set ifname=eth0 only.
Or add fallback to eth0 into preinit if both pi_ifname and ifname are
undefined.
In last case no need ramips_set_preinit_iface() at all.
Was tested for rt5350. Check for other SOCs is needed.
