mlxsw: spectrum: Add a new type of KVD linear record (90ea0bb5) · Commits · 戴 / test

When the device needs to flood an overlay packet to remote VTEPs it retrieves a pointer to the head of a linked-list of records that store the IP addresses of these VTEPs. These records are stored in the KVD linear memory and configured via the Tunneling NVE Underlay Multicast Table (TNUMT) register. Add a new KVD linear entry type for these records, so that we will be able to allocate and free them. Signed-off-by:
