Package: Network Install Initramfs "initrd.gz". The kernel module "phy_gmii_sel.ko" is missing from initrd.gz of dists/bullseye/main/installer-armhf/current/images/netboot/netboot.tar.gz (date 2022-03-22 17:37). This will leads to the error "cpsw 4a100000.ethernet: 0: Error retrieving port phy: -517" and the NIC is thus missing from the Beaglebone black system. The NIC will be present if the phy_gmii_sel.ko is added into the initrd.gz in dists/bullseye/main/installer-armhf/current/images/netboot/netboot.tar.gz.
