Subject: [PATCH 2/4] net: dsa: add bridge member iteration macro
|
|
|
|
Drivers that offload bridges need to iterate over the ports that are
|
|
members of a given bridge, for example to rebuild per-port forwarding
|
|
bitmaps when membership changes. Currently drivers typically open-code
|
|
this by combining dsa_switch_for_each_user_port() with a
|
|
dsa_port_offloads_bridge_dev() check, or cache bridge membership
|
|
within the driver.
|
|
|
|
Add dsa_switch_for_each_bridge_member() macro to express this pattern
|
|
directly, and use it for the existing dsa_bridge_ports() inline
|
|
helper.
