+This annotation is used to indicate that the buffer associated with an __sz or __szk

+Internals
+=========
+
+This section of the document is targeted at Linux developers and describes
+aspects of the map implementations that are not considered stable ABI. The
+following details are subject to change in future versions of the kernel.
+
+``BPF_MAP_TYPE_LRU_HASH`` and variants
+--------------------------------------
+
+Updating elements in LRU maps may trigger eviction behaviour when the capacity
+of the map is reached. There are various steps that the update algorithm
+attempts in order to enforce the LRU property which have increasing impacts on
+other CPUs involved in the following operation attempts:
+
+- Attempt to use CPU-local state to batch operations
+- Attempt to fetch free nodes from global lists
+- Attempt to pull any node from a global list and remove it from the hashmap
+- Attempt to pull any node from any CPU's list and remove it from the hashmap
+
+This algorithm is described visually in the following diagram. See the
+description in commit 3a08c2fd7634 ("bpf: LRU List") for a full explanation of
+the corresponding operations:
+
+.. kernel-figure::  map_lru_hash_update.dot
+   :alt:    Diagram outlining the LRU eviction steps taken during map update.
+
+   LRU hash eviction during map update for ``BPF_MAP_TYPE_LRU_HASH`` and
+   variants. See the dot file source for kernel function name code references.
+
+Map updates start from the oval in the top right "begin ``bpf_map_update()``"
+and progress through the graph towards the bottom where the result may be
+either a successful update or a failure with various error codes. The key in
+the top right provides indicators for which locks may be involved in specific
+operations. This is intended as a visual hint for reasoning about how map
+contention may impact update operations, though the map type and flags may
+impact the actual contention on those locks, based on the logic described in
+the table above. For instance, if the map is created with type
+``BPF_MAP_TYPE_LRU_PERCPU_HASH`` and flags ``BPF_F_NO_COMMON_LRU`` then all map
+properties would be per-cpu.

+Quality of service
+==================
+
+
+Hardware algorithms used in scheduling
+--------------------------------------
+
+octeontx2 silicon and CN10K transmit interface consists of five transmit levels
+starting from SMQ/MDQ, TL4 to TL1. Each packet will traverse MDQ, TL4 to TL1
+levels. Each level contains an array of queues to support scheduling and shaping.
+The hardware uses the below algorithms depending on the priority of scheduler queues.
+once the usercreates tc classes with different priorities, the driver configures
+schedulers allocated to the class with specified priority along with rate-limiting
+configuration.
+
+1. Strict Priority
+
+      -  Once packets are submitted to MDQ, hardware picks all active MDQs having different priority
+         using strict priority.
+
+2. Round Robin
+
+      - Active MDQs having the same priority level are chosen using round robin.
+
+
+Setup HTB offload
+-----------------
+
+1. Enable HW TC offload on the interface::
+
+        # ethtool -K <interface> hw-tc-offload on
+
+2. Crate htb root::
+
+        # tc qdisc add dev <interface> clsact
+        # tc qdisc replace dev <interface> root handle 1: htb offload
+
+3. Create tc classes with different priorities::
+
+        # tc class add dev <interface> parent 1: classid 1:1 htb rate 10Gbit prio 1
+
+        # tc class add dev <interface> parent 1: classid 1:2 htb rate 10Gbit prio 7
