General issue report

The section 'How to Improve Wi-Fi Performance' in the WiFi Driver documentation needs some improvement.

There are some mistakes e.g. the docs say to set the value LWIP_IRAM_OPTIMIZATION to 13 in order to optimize throughput yet that value is a boolean one and can therefor only be set 0 or 1. The section specifically about PSRAM usage mentions the values TCP_SND_BUF_DEFAULT and TCP_WND_DEFAULT and suggests to set them to 85K. However this option can only be enabled once CONFIG_SPIRAM_TRY_ALLOCATE_WIFI_LWIP has been enabled.

hi @higaski Sorry for the delay in getting back to you, but we've received your question and will fix the problem in the next update, where the 13 in LWIP_IRAM_OPTIMIZATION stands for the amount of ram space used to turn on the option.
