      mlxsw: spectrum: Replace vPorts with Port-VLAN · c57529e1
      由 Ido Schimmel 提交于 
      As explained in the cover letter, since the introduction of the bridge
offload in the mlxsw driver, information related to the offloaded bridge
and bridge ports was stored in the individual port struct,
mlxsw_sp_port.

This lead to a bloated struct storing both physical properties of the
port (e.g., autoneg status) as well as logical properties of an upper
bridge port (e.g., learning, mrouter indication). While this might work
well for simple devices, it proved to be hard to extend when stacked
devices were taken into account and more advanced use-cases (e.g., IGMP
snooping) considered.

This patch removes the excess information from the above struct and
instead stores it in more appropriate structs that represent the bridge
port, the bridge itself and a VLAN configured on the bridge port.

The membership of a port in a bridge is denoted using the Port-VLAN
struct, which points to the bridge port and also member in the bridge
VLAN group of the VLAN it represents. This allows us to completely
remove the vPort abstraction and consolidate many of the code paths
relating to VLAN-aware and unaware bridges.

Note that the FID / vFID code is currently duplicated, but this will
soon go away when the common FID core will be introduced.

      mlxsw: spectrum: Don't create FIDs upon creation of VLAN uppers · ed9ddd3a
      由 Ido Schimmel 提交于 
      Up until now we used to create FIDs upon the creation of VLAN uppers on
top of the VLAN-aware bridge. This was done so that in case a router
interface (RIF) was configured on top of the bridge, the FID would
already be there.

Instead, simplify the code and only create the FID upon RIF creation.

This is an intermediary step towards the introduction of the common FID
core, in which this code would be completely removed.

      mlxsw: spectrum: Don't lose bridge port device during enslavement · f0cebd81
      由 Ido Schimmel 提交于 
      Currently, when port netdevs (or their uppers) are enslaved to a bridge,
we simply propagate the CHANGEUPPER event all the way down and lose the
context of the actual netdevice used as the bridge port.

This leads to a lot of information hanging off the ports (and vPorts),
which doesn't logically belong there, such as mrouter indication and
unknown unicast flood state.

Following patches are going to put the mlxsw_sp_port struct on diet and
instead introduce a bridge port struct, where the above mentioned
information belongs. But in order to do that, we need to be able to
determine the bridge port netdevice, so propagate it down.

      mlxsw: spectrum_router: Replace vPorts with Port-VLAN · 7cbecf24
      由 Ido Schimmel 提交于 
      We're going to get rid of vPorts completely later in the patchset, but
the router code is self-contained, so it's a good candidate to start the
transition with.

Convert all the functions that expects to operate on a vPort to operate
on a Port-VLAN instead.

      mlxsw: spectrum: Change signature of FID leave function · ce95e154
      由 Ido Schimmel 提交于 
      When a vPort is destroyed, it leaves the FID it's currently mapped to
(if any) and drops the reference. The FID's leave function expects to
get the vPort as its argument, but this will have to change when the
vPort model is retired.

Change the function signature to expect a Port-VLAN struct instead and
patch the call sites accordingly.

The code introduced in this patch will be removed later in the patchset,
but this intermediary step is required in order to ease the code review.

      mlxsw: spectrum: Introduce Port-VLAN structure · 31a08a52
      由 Ido Schimmel 提交于 
      This is the first step in the transition from the vPort model to a
unified Port-VLAN structure. The new structure is defined and created /
destroyed upon invocation of the 8021q ndos, but it's not actually used
throughout the code.

Subsequent patches will initialize it correctly and also create /
destroy it upon switchdev's VLAN object.

      mlxsw: spectrum: Set port's mode according to FID mappings · 4aafc368
      由 Ido Schimmel 提交于 
      We currently transition the port to "Virtual mode" upon the creation of
its first VLAN upper, as we need to classify incoming packets to a FID
using {Port, VID} and not only the VID.

However, it's more appropriate to transition the port to this mode when
the {Port, VID} are actually mapped to a FID. Either during the
enslavement of the VLAN upper to a VLAN-unaware bridge or the
configuration of a router port.

Do this change now in preparation for the introduction of the FID core,
where this operation will be encapsulated.

To prevent regressions, this patch also explicitly configures an OVS
slave to "Virtual mode". Otherwise, a packet that didn't hit an ACL rule
could be classified to an existing FID based on a global VID-to-FID
mapping, thus not incurring a FID mis-classification, which would
otherwise trap the packet to the CPU to be processed by the OVS daemon.

      mlx5e: add CONFIG_INET dependency · 2432a3fb

      We now reference the arp_tbl, which requires IPv4 support to be

drivers/net/built-in.o: In function `mlx5e_tc_update_neigh_used_value':

This adds a Kconfig dependency for it.
