This patch series adds a few helpers to DSA core for clarity and readability but brings no functional changes.
A dsa_slave_notify helper calls the DSA notifiers when (un)registering a slave device. Most of the DSA slave code only needs to access the dsa_port structure, not the dsa_slave_priv (which only contains a few PHY-specific members). Thus a dsa_slave_to_port helper returns a dsa_port structure of a slave device. A dsa_slave_to_master returns the master device of a slave device. After that the netdev member of the dsa_port structure is split into two explicit master and slave members to avoid confusion, and a dsa_to_port helper is added for switch drivers to get a const reference to a port. Changes in v2: - prefer dsa_slave_to_master instead of dsa_slave_get_master - rename dsa_master_get_slave to dsa_master_find_slave - pack master and slave net devices into an anonymous union - add dsa_to_port public helper for switch drivers - add Reviewed-by tags from Florian Vivien Didelot (7): net: dsa: use port's cpu_dp when creating a slave net: dsa: add slave notify helper net: dsa: add slave to port helper net: dsa: add slave to master helper net: dsa: rename dsa_master_get_slave net: dsa: split dsa_port's netdev member net: dsa: add dsa_to_port helper drivers/net/dsa/b53/b53_common.c | 4 +- drivers/net/dsa/bcm_sf2.c | 6 +- drivers/net/dsa/lan9303-core.c | 2 +- drivers/net/dsa/mt7530.c | 6 +- drivers/net/dsa/mv88e6060.c | 2 +- drivers/net/dsa/mv88e6xxx/chip.c | 10 +- drivers/net/dsa/qca8k.c | 4 +- include/net/dsa.h | 14 ++- net/dsa/dsa.c | 6 +- net/dsa/dsa2.c | 20 ++-- net/dsa/dsa_priv.h | 26 +++-- net/dsa/legacy.c | 20 ++-- net/dsa/slave.c | 227 +++++++++++++++++++-------------------- net/dsa/tag_brcm.c | 11 +- net/dsa/tag_dsa.c | 12 +-- net/dsa/tag_edsa.c | 12 +-- net/dsa/tag_ksz.c | 6 +- net/dsa/tag_lan9303.c | 6 +- net/dsa/tag_mtk.c | 6 +- net/dsa/tag_qca.c | 7 +- net/dsa/tag_trailer.c | 6 +- 21 files changed, 211 insertions(+), 202 deletions(-) -- 2.14.2
