Comments/Problems:

Installer can't properly bring up BCM53125 with DSA - missing DSA module tag_brcm. Also, no USB is detected.

After replacing kernel modules in installer initrd.gz from linux-image-5.10.0-5-armmp_5.10.26-1_armhf.deb
DSA properly detect and configure Broadcom BCM53125 switch, but unable to use it. Installer
try enable individual interface (wan) and disable all other, but for DSA master
interface (eth0) MUST be enabled before wan interface and stay up.

After connect USB network card - installer is able to detects network and complete the installation.
