This is a preparation patch for the removal of the DSA switch methods ->port_bridge_tx_fwd_offload() and ->port_bridge_tx_fwd_unoffload(). The plan is for the switch to report whether it offloads TX forwarding directly as a response to the ->port_bridge_join() method. This change deals with the noisy portion of converting all existing function prototypes to take this new boolean pointer argument. The bool is placed in the cross-chip notifier structure for bridge join, and a reference to it is provided to drivers. In the next change, DSA will then actually look at this value instead of calling ->port_bridge_tx_fwd_offload(). Signed-off-by: Vladimir Oltean <vladimir.oltean@nxp.com> ---

v1->v2: patch is kind of new, the noisy conversion from v1's patch 6/6 has been split into a separate change. Had to drop Alvin's Reviewed-by tag because he technically did not review the change in this form. drivers/net/dsa/b53/b53_common.c | 3 ++- drivers/net/dsa/b53/b53_priv.h | 3 ++- drivers/net/dsa/dsa_loop.c | 3 ++- drivers/net/dsa/hirschmann/hellcreek.c | 3 ++- drivers/net/dsa/lan9303-core.c | 3 ++- drivers/net/dsa/lantiq_gswip.c | 3 ++- drivers/net/dsa/microchip/ksz_common.c | 3 ++- drivers/net/dsa/microchip/ksz_common.h | 2 +- drivers/net/dsa/mt7530.c | 2 +- drivers/net/dsa/mv88e6xxx/chip.c | 3 ++- drivers/net/dsa/ocelot/felix.c | 2 +- drivers/net/dsa/qca8k.c | 3 ++- drivers/net/dsa/rtl8366rb.c | 3 ++- drivers/net/dsa/sja1105/sja1105_main.c | 3 ++- drivers/net/dsa/xrs700x/xrs700x.c | 2 +- include/net/dsa.h | 3 ++- net/dsa/dsa_priv.h | 1 + net/dsa/switch.c | 3 ++- 18 files changed, 31 insertions(+), 17 deletions(-)diff --git a/drivers/net/dsa/b53/b53_common.c b/drivers/net/dsa/b53/b53_common.c index 4e41b1a63108..3867f3d4545f 100644 --- a/drivers/net/dsa/b53/b53_common.c +++ b/drivers/net/dsa/b53/b53_common.c@@ -1860,7 +1860,8 @@ int b53_mdb_del(struct dsa_switch *ds, int port, } EXPORT_SYMBOL(b53_mdb_del);
