Subject: dsa: mv88e6xxx: mv88e6321 rsvd2cpu

Hi all,

working on some rstp stuff at userspace level, (kernel stp
disabled), i have seen bpdu packets was forwarded over bridge
ports generating chaos and loops. As far as i know, 802.1d asks
bpdus are not forwarded.

Finally found a solution, adding mv88e6185_g2_mgmt_rsvd2cpu()
for mv88e6321.
Is it a proper solution ? Is there any specific reason why
rsvd2cpu was not implemented for my 6321 ?
I can send the patch i am using actually. in case.

Thanks a lot.

Regards,
