Do we know which Linux 5.x.x driver is used for FC900E module?
Kind regards,

There is an answer from technical support.
Qualcom chip is QCA9377-3.
Linux driver is proprietary (out of Linux tree) and exists for Linux 4.14 and below probably. It is based on some early version of ath (6 or so) driver.
