Comment 16 for bug 1890641

As indicated from SRU justification section, the solution is to backport a few new fw blobs. So the steps were to verify if the downloaded deb contains exactly the binaries I proposed:

  $ dpkg-deb -R linux-firmware_*.deb .
  $ md5sum lib/firmware/rtl_nic/rtl8153*
  $ md5sum ~/linux-firmware.git/rtl_nic/rtl8153*

and to find a spare platform, install that deb from bionic-proposed, boot with RTL8153 usb-ether attached, and check if network interface is available.
