USB CDC as ~uart

Usage example:

import machine

RX_BUFFER_SIZE_IN_BYTES = 2048
cdc = machine.CDC(rxbuf=RX_BUFFER_SIZE_IN_BYTES) # 1024 bytes by default

buf = ''
for i in range(1000):
    buf += f'{i:06d}\r\n'

cdc.write(buf)

W5500 support fixed

Usage example:

import network
from machine import SPI, Pin

spi1 = SPI(1, sck=Pin(14), mosi=Pin(13), miso=Pin(12))
lan = network.LAN(phy_type=network.PHY_W5500, phy_addr=0, spi=spi1, int=Pin(4), cs=Pin(5))

lan.config(mac='\xDE\xAD\xBE\xEF\xCA\xFE')
lan.active(True)

lan.ifconfig(('192.168.123.100', '255.255.255.0', '192.168.123.1', '8.8.8.8'))
