  "message": "drivers: wifi: esp: rely on +IPD after each +CIPRECVDATA\n\nDump of communication between ESP chip and Zephyr shows that\n+IPD:\u003csock\u003e,\u003cbytes_avail\u003e is always received after +CIPRECVDATA. This\nmeans that we don\u0027t need to update sock-\u003ebytes_avail in esp_workq\nthread. Additionally there is no need to schedule next AT+CIPRECVDATA\nrequest, as that will be done by +IPD handler anyway.\n\nRelying on +IPD to be received after each +CIPRECVDATA (as long as there\nis some more data to be received) allows to simplify operations on\nsock-\u003ebytes_avail. From now on only esp_rx thread will update its value\nand schedule AT+CIPRECVDATA in esp_workq thread. Then in\nsock-\u003ebytes_avail will be treated as \"readonly\" in esp_workq\nthread. This allows to prevent race condition when both esp_rx and\nesp_workq threads could potentially update value of sock-\u003ebytes_avail\nvalue at the same time.\n\n\u003csock\u003e,CLOSED message is received always after retrieving all data from\nESP chip (using AT+CIPRECVDATA), so there is no need to check whether\nthere are more bytes to be received before marking socket as closed in\nZephyr driver.\n\nSigned-off-by: Marcin Niestroj \u003cm.niestroj@grinn-global.com\u003e\n",
