Subject: [PATCH net-next 07/13] mlxsw: Add support for VLAN RIFs
Date: Thu, 30 Jun 2022 11:22:51 +0300	[thread overview]
Message-ID: <20220630082257.903759-8-idosch@nvidia.com> (raw)
In-Reply-To: <20220630082257.903759-1-idosch@nvidia.com>

From: Amit Cohen <amcohen@nvidia.com>

Router interfaces (RIFs) constructed on top of VLAN-aware bridges are of
'VLAN' type, whereas RIFs constructed on top of VLAN-unaware bridges are of
'FID' type.

Currently 802.1Q FIDs are emulated using 802.1D FIDs, therefore VLAN RIFs
are emulated using FID RIFs. As part of converting the driver to use
unified bridge model, 802.1Q FIDs and VLAN RIFs will be used.

The egress FID is required for VLAN RIFs in Spectrum-2 and above, but not
in Spectrum-1, as in Spectrum-1 the mapping for VLAN RIFs is VID->FID,
while in other ASICs it is FID->FID. The reason for the change is that it
is more scalable to reuse the FID->FID entry than creating multiple
{Port, VID}->FID entries for the router port. Use the existing operation
structure to separate the configuration between different ASICs.

Add support for VLAN RIFs, most of the configurations are same to FID
RIFs.
