CONFIG_NET_TX_STACK_SIZE

TX thread stack size

Type: int

Help

Set the TX thread stack size in bytes. The TX thread is waiting
data from application. Each network interface will start one
TX thread for sending network packets destined to it.
This value is a baseline and the actual TX stack size might
be bigger depending on what features are enabled.
