Subject: [PATCH 01/13] net: dsa: mt7530: iterate using
|
|
dsa_switch_for_each_user_port in bridging ops
|
|
|
|
Avoid repeated calls to dsa_to_port() (some hidden behind dsa_is_user_port
|
|
and some in plain sight) by keeping two struct dsa_port references: one
|
|
to the port passed as argument, and another to the other ports of the
|
|
switch that we're iterating over.
|
|
|
|
dsa_to_port(ds, i) gets replaced by other_dp, i gets replaced by
|
|
other_port which is derived from other_dp->index, dsa_is_user_port is
|
|
handled by the DSA iterator.
