| Interval in seconds of Network buffer allocation warnings which are |
| generated when a buffer cannot immediately be allocated with K_FOREVER |
| which may lead to deadlocks. Setting it to 0 makes warnings to be |
| printed only once per allocation. |

| bool "Network buffer pool usage tracking" |
| help |
| Enable network buffer pool tracking. This means that: |
| * amount of free buffers in the pool is remembered |
| * total size of the pool is calculated |
| * pool name is stored and can be shown in debugging prints |

| config NET_BUF_ALIGNMENT |
| int "Network buffer alignment restriction" |
| default 0 |
| help |
| Alignment restriction for network buffers. This is useful for |
| some hardware IP with DMA that requires the buffers to be aligned |
| to a certain byte boundary, or dealing with cache line restrictions. |
| Default value of 0 means the alignment will be the size of a void pointer, |
| any other value will force the alignment of a net buffer in bytes. |
