struct uniform_reo_cmd_header cmd_header
			
			Consumer: REO
			
			Producer: SW
			
			
			Details for command execution tracking purposes.

flush_addr_31_0
			
			Consumer: REO
			
			Producer: SW
			
			
			Address (lower 32 bits) of the descriptor to flush
			
			<legal all>

flush_addr_39_32
			
			Consumer: REO
			
			Producer: SW
			
			
			Address (upper 8 bits) of the descriptor to flush
			
			<legal all>

forward_all_mpdus_in_queue
			
			Is only allowed to be set when the flush address
			corresponds with a REO descriptor.
			
			
			When set, REO shall first forward all the MPDUs held in
			the indicated re-order queue, before flushing the descriptor
			from the cache.
			
			<legal all>

release_cache_block_index
			
			Field not valid when Flush_entire_cache is set.
			
			
			If SW has previously used a blocking resource that it
			now wants to re-use for this command, this bit shall be set.
			It prevents SW from having to send a separate
			REO_UNBLOCK_CACHE command.
			
			
			When set, HW will first release the blocking resource
			(indicated in field 'Cache_block_resouce_index') before this
			command gets executed.
			
			If that resource was already unblocked, this will be
			considered an error. This command will not be executed, and
			an error shall be returned.
			
			<legal all>

cache_block_resource_index
			
			Field not valid when Flush_entire_cache is set.
			
			
			Indicates which of the four blocking resources in REO
			will be assigned for managing the blocking of this
			(descriptor) address 
			
			<legal all>

flush_without_invalidate
			
			Field not valid when Flush_entire_cache is set.
			
			
			When set, REO shall flush the cache line contents from
			the cache, but there is NO need to invalidate the cache line
			entry... The contents in the cache can be maintained. This
			feature can be used by SW (and DV) to get a current snapshot
			of the contents in the cache
			
			
			<legal all>

block_cache_usage_after_flush
			
			Field not valid when Flush_entire_cache is set.
			
			
			When set, REO shall block any cache accesses to this
			address till explicitly unblocked. 
			
			
			Whenever SW sets this bit, SW shall also set bit
			'Forward_all_mpdus_in_queue' to ensure all packets are
			flushed out in order to make sure this queue desc is not in
			one of the aging link lists. In case SW does not want to
			flush the MPDUs in the queue, see the recipe description
			below this TLV definition.
			
			
			The 'blocking' index to be used for this is indicated in
			field 'cache_block_resource_index'. If SW had previously
			used this blocking resource and was not freed up yet, SW
			shall first unblock that index (by setting bit
			Release_cache_block_index) or use an unblock command.
			
			
			If the resource indicated here was already blocked (and
			did not get unblocked in this command), it is considered an
			error scenario...
			
			No flush shall happen. The status for this command shall
			indicate error.
			
			
			<legal all>

flush_entire_cache
			
			When set, the entire cache shall be flushed. The entire
			cache will also remain blocked, till the
			'REO_UNBLOCK_COMMAND' is received with bit unblock type set
			to unblock_cache. All other fields in this command are to be
			ignored.
			
			
			Note that flushing the entire cache has no changes to
			the current settings of the blocking resource settings
