Public bug reported:
Linux Mint 20.3, based on Ubuntu 20.04
$ uname -a
Linux mintbook 5.15.0-131-generic #141~20.04.1-Ubuntu SMP Thu Jan 16 18:38:51

I have an ASUS notebook and it has no RJ45 socket. I use USB Gigabit
adapter based on RTL8153. So far it worked OK but I have found today
that I cannot configure alias with ifconfig. Try to configure alias IP
address with ifconfig changes default interface. It looks like a bug in
the RTL8153 driver.
$ ethtool -i enx00e04c68002f
driver: r8152
version: v1.12.13
firmware-version: rtl8153b-2 v1 10/23/19
expansion-rom-version:
bus-info: usb-0000:00:14.0-2
supports-statistics: yes
supports-test: no
supports-eeprom-access: no

supports-priv-flags: no
$ lsusb | grep 8153
Bus 002 Device 004: ID 0bda:8153 Realtek Semiconductor Corp. RTL8153 Gigabit
Ethernet Adapter
Steps to replicate:
1) Connect USB adapter to a LAN, I assume I received IP address 192.168.1.11
from DHCP server.
2) check with ifconfig what is IP address on interface enx00e04c68002f
3) define alias, 'sudo ifconfig enx00e04c68002f:33 192.168.33.11'
4) check with ifconfig the result
I see that there is no new interface enx00e04c68002f:33 and that IP
address on interface enx00e04c68002f was changed to 192.168.33.11. That
is a bug!
Expected behavior:
Interface enx00e04c68002f will keep IP address assigned from DHCP server, like
192.168.1.11
New interface enx00e04c68002f:33 will be added with IP address 192.168.33.11
This report is for an older kernel and older Ubuntu distribution. I
assume the bug is still in the newer kernel, this has to be retested...
