For interaction with the DSA layer, the struct net_device contains a dsa_ptr, which currently points to a dsa_switch_tree object. This is only valid for a switch fabric with a single CPU port. In order to support switch fabrics with multiple CPU ports, we first need to change the type of dsa_ptr to what it really is: a dsa_port object. This is what this patchset does. The first patches adds a dsa_master_get_slave helper and cleans up portions of DSA core to make the next patches more readable. These next patches prepare the xmit and receive hot paths and finally change dsa_ptr. Changes in v2: - introduce dsa_master_get_slave helper to simplify patch 6 - keep hot path data at beginning of dsa_port for cacheline 1 Vivien Didelot (7): net: dsa: add master helper to look up slaves net: dsa: use cpu_dp in master code net: dsa: use temporary dsa_device_ops variable net: dsa: add tagging ops to port net: dsa: prepare master receive hot path net: dsa: change dsa_ptr for a dsa_port net: dsa: remove tag ops from the switch tree include/linux/netdevice.h | 4 ++-- include/net/dsa.h | 19 ++++++++----------- net/dsa/dsa.c | 6 +++--- net/dsa/dsa2.c | 15 ++++++++++----- net/dsa/dsa_priv.h | 27 +++++++++++++++++++++------ net/dsa/legacy.c | 15 ++++++++++----- net/dsa/master.c | 47 ++++++++++++++++++++++------------------------- net/dsa/slave.c | 3 +-- net/dsa/tag_brcm.c | 9 ++------- net/dsa/tag_dsa.c | 18 ++---------------- net/dsa/tag_edsa.c | 18 ++---------------- net/dsa/tag_ksz.c | 9 +++------ net/dsa/tag_lan9303.c | 20 ++------------------ net/dsa/tag_mtk.c | 16 +++------------- net/dsa/tag_qca.c | 17 +++-------------- net/dsa/tag_trailer.c | 9 +++------ 16 files changed, 97 insertions(+), 155 deletions(-) -- 2.14.1
