lwip:refractor to the description about this menuconfig option
2016-11-16 21:22:20 -05:00
If this feature is enabled, all traffic from layer2(WIFI Driver) will be
copied to a new buffer before sending it to layer3(LWIP stack), freeing
the layer2 buffer.
Please be notified that the total layer2 receiving buffer is fixed and
ESP32 currently supports 25 layer2 receiving buffer, when layer2 buffer
runs out of memory, then the incoming packets will be dropped in hardware.
The layer3 buffer is allocated from the heap, so the total layer3 receiving
buffer depends on the available heap size, when heap runs out of memory,
no copy will be sent to layer3 and packet will be dropped in layer2.
Please make sure you fully understand the impact of this feature before
enabling it.

Sockets take up a certain amount of memory, and allowing fewer
sockets to be open at the same time conserves memory. Specify

'Merge branch 'thread_local_storage_delete_callbacks' into 'master' The thread-local-storage feature in FreeRTOS attaches an application-usable array of pointers to a thread control block. These pointers usually point to a structure the thread allocates. When a thread gets (voluntarily or involuntarily) destroyed, this memory can leak. This merge adds a matching second array of user-settable pointers to destructor routines. As soon as the task gets cleaned up (which happens in the idle thread), the destructors get called and the memory can be freed. See merge request !19
