ECM USB Driver For ESP32-S3 (IDFGH-14232)

[ParthaSarathiMishra]

Is your feature request related to a problem?

Presently ESP32-S3 USB driver uses CDC ACM driver for acting as a host. It works as a virtual COM port. But issue is its very slow when doing network operations(like FTP upload) using a modem (like Quectel BG77, etc) over USB. The same modem when connected to PC with ECM driver makes the operation around 20 times faster. The AT command layer is adding overhead.

Describe the solution you'd like.

It would be better if there is native ECM driver available for esp-idf which can take advantages of full bandwidth of the modem and reduce overhead and latency in network operations. Because many projects use LTE modem and not WiFi for networking.

Describe alternatives you've considered.
