Subject: [PATCH net-next 00/16] net: dsa: turn arrays of ports into a list
Date: Sat, 19 Oct 2019 23:19:25 -0400 [thread overview]
Message-ID: <20191020031941.3805884-1-vivien.didelot@gmail.com> (raw)
The dsa_switch structure represents the physical switch device itself,
and is allocated by the driver. The dsa_switch_tree and dsa_port structures
represent the logical switch fabric (eventually composed of multiple switch
devices) and its ports, and are allocated by the DSA core.
This branch lists the logical ports directly in the fabric which simplifies
the iteration over all ports when assigning the default CPU port or configuring
the D in DSA in drivers like mv88e6xxx.
This also removes the unique dst->cpu_dp pointer and is a first step towards
supporting multiple CPU ports and dropping the DSA_MAX_PORTS limitation.
Because the dsa_port structures are not tight to the dsa_switch structure
anymore, we do not need to provide an helper for the drivers to allocate a
switch structure. Like in many other subsystems, drivers can now embed their
dsa_switch structure as they wish into their private structure. This will
be particularly interesting for the Broadcom drivers which were currently
limited by the dynamically allocated array of DSA ports.
The series implements the list of dsa_port structures, makes use of it,
then drops dst->cpu_dp and the dsa_switch_alloc helper.
Vivien Didelot (16):
net: dsa: use dsa_to_port helper everywhere
net: dsa: add ports list in the switch fabric
net: dsa: use ports list in dsa_to_port
net: dsa: use ports list to find slave
net: dsa: use ports list to setup switches
net: dsa: use ports list for routing table setup
net: dsa: use ports list to find a port by node
net: dsa: use ports list to setup multiple master devices
net: dsa: use ports list to find first CPU port
net: dsa: use ports list to setup default CPU port
net: dsa: mv88e6xxx: silently skip PVT ops
net: dsa: mv88e6xxx: use ports list to map port VLAN
net: dsa: mv88e6xxx: use ports list to map bridge
net: dsa: sja1105: register switch before assigning port private data
net: dsa: allocate ports on touch
net: dsa: remove dsa_switch_alloc helper
