We try to strictly follow the naming used in the IEEE 802.1D-2004 standard, as
it eases crossreferencing it. In it this function is called
updtRoleDisabledTree().

It's still correct, but it introduces unnecessary flooding operations. The
standard claims that rstp should be able to flush entries pertaining to a
single port by setting the fdbflush per-port variable (see 17.19.7).
In lib/mac-learning.h there is a function (mac_learning_flush()) to flush the
whole table. Is there a function to flush the entries pertaining to a single
port?
