Does esp_wifi_start suspend tasks on the app core?

[jcsbanks]

I get RMT overflows with esp_wifi_start. I drain RMT buffers in a 5ms task and usually only use 1 or 2 of the 64 RMT records, but when WiFi starts I am getting overflow.

I am going to try this week to narrow it down and then produce minimal example if I cannot, but would like to know if esp_wifi_start is special in some way to other tasks, even on the other core.
