	  Enables handling of SMP commands received over shell.  This allows
	  the shell to be use for both mcumgr commands and shell commands.

config MCUMGR_TRANSPORT_SHELL_MTU
	int "Shell SMP MTU"
	default 256
	help
	  Maximum size of SMP frames sent and received over shell.  This value
	  must satisfy the following relation:
	  MCUMGR_TRANSPORT_SHELL_MTU <= MCUMGR_TRANSPORT_NETBUF_SIZE + 2

config MCUMGR_TRANSPORT_SHELL_RX_BUF_COUNT
	int "Shell SMP RX buffer count"
	default 2
	help
	  Number of buffers used for receiving SMP fragments over shell.

config MCUMGR_TRANSPORT_SHELL_INPUT_TIMEOUT
	bool "Shell input expiration"
	help
	  If enabled, will time out a partial or erroneous MCUmgr command
	  received via the shell transport after a given time. This prevents
	  the shell from becoming locked if it never receives the full packet
	  that a header indicated it would receive.

config MCUMGR_TRANSPORT_SHELL_INPUT_TIMEOUT_TIME
	int "Shell input expiration timeout"
	depends on MCUMGR_TRANSPORT_SHELL_INPUT_TIMEOUT
	default 3000
	help
	  Time (in msec) after receiving a valid MCUmgr header on the serial
	  transport before considering it as timed out and returning the shell
	  to normal operation.
