Help¶

If enabled, then it is possible to fine-tune network packet pool for each context when sending network data. If this setting is enabled, then you should define the context pools in your application using NET_PKT_TX_POOL_DEFINE() and NET_PKT_DATA_POOL_DEFINE() macros and tie these pools to desired context using the net_context_setup_pools() function.

Direct dependencies¶

!NET_RAW_MODE && NETWORKING

(Includes any dependencies from ifs and menus.)
