Increase network buffer size and stack sizes for frdm_imx91/mimx9131 to stabilize TCP/UDP traffic (zperf) on 5GHz Wi-Fi: - Set NET_BUF_DATA_SIZE=1600 to fix TCP RX crash caused by net_buf being too small to hold a TCP segment (default is 128 bytes). Note: NET_PKT/BUF RX/TX counts are already set to sufficient values in overlay_iw610.conf and do not need to be overridden here. - Add ZPERF_WORK_Q_STACK_SIZE=8192 to fix zperf_work_q stack overflow during TCP TX. - Increase NXP Wi-Fi task stack sizes (TX/CORE/SCAN/MON/POWERSAVE/ DRIVER/WLCMGR) to prevent stack sentinel triggers. - Increase NET_TX_STACK_SIZE and NET_RX_STACK_SIZE to 16384 to fix intermittent TCP TX crash (work->queue == NULL assert). - Increase NET_MGMT_EVENT_STACK_SIZE to 16384 and SHELL_STACK_SIZE to 16384 for stability.

please try if it can work with smaller stack size.
