bool "Enable copy between Layer2 and Layer3 packets"

help
|
|
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.
