Note that custom parameters specified through this field can not also be set in the corresponding named parameters: .. code-block:: text ID Field Name ---------------- 0x1 hpack_table_size 0x3 max_concurrent_streams 0x4 initial_stream_window_size Collisions will trigger config validation failure on load/update. Likewise, inconsistencies between custom parameters with the same identifier will trigger a failure.
