| The number of net_bufs to allocate for mcumgr. These buffers are |
| used for both requests and responses. |

| help |
| The size, in bytes, of each mcumgr buffer. This value must satisfy |
| the following relation: |
| MCUMGR_BUF_SIZE >= transport-specific-MTU + transport-overhead |
| In case when MCUMGR_SMP_SHELL is enabled this value should be set to |
| at least SHELL_BACKEND_DUMMY_BUF_SIZE + 32. |

| default 4 |
| help |
| The size, in bytes, of user data to allocate for each mcumgr buffer. |
| |
| Different mcumgr transports impose different requirements for this |
| setting. A value of 4 is sufficient for UART, shell, and bluetooth. |
| For UDP, the userdata must be large enough to hold a IPv4/IPv6 address. |
