b53 tags on bpi-r1 (bcm53125)

[Jochen Friedrich]

Hi Florian,

i just tested the latest DSA patches for b53 on a bpi-r1 device (net: 
dsa: b53: Turn on Broadcom tags).

Unfortunately, the bcm53125 does not seem to handle the broadcom tags on 
CPU port although tuned on b53_brcm_hdr_setup(). The tag is still 
visible on a device connected to one of the switch ports.

I wonder if there is something else necessary to make the chip handle 
the tags or if the chip doesn't support broadcom tags after all. The 
documentation at 
https://sourceforge.net/p/ohvesw/svn/12/tree/document/bcm/53125U-DS02-R.pdf 
doesn't document register 3 in the management page, at all...


Thanks,

Jochen
