** Description changed:

+ [Impact]
+ 7906 should be used against kernels not newer than v5.0, especially v5.3, 
which has already known regression that fails Wi-Fi association.
+ 
+ [Fix]
+ Add "OBSOLETE_BY=5.0.0" to dkms conf.
+ 
+ [Test Case]
+ 1. Install packages in ppa:vicamo/ppa-1859389
+ 2. Modules will still be built, but the original in-tree kernel modules won't 
be overridden. From `dkms status` one should find following warnings for 
kernels >= 5.0.0:
+ 
+   WARNING! Diff between built and installed module!
+ 
+ [Regression Potential]
+ 7906 is meant for 4.15 kernels for Bionic. New models should have been 
supported directly in 5.x kernels via SRU. So the regression potential should 
be LOW here.
+ 
+ ========== original bug description ==========
+ 
  Ubuntu kernel v5.0 or above should have enough backports to enable AX201
  family, there should be little reason one would need DKMS on such
  systems. Besides, 7906 has been pretty outdated in comparison to what we
  already have in kernel, actually it could even cause more problems than
  gains.
  
  Therefore, for Bionic 4.15 kernels (-generic & -oem) we will still
  recommends the use of this DKMS as v4.15 is even more outdated. For
  Bionic hwe kernels (5.0) or hwe-edge (5.3) kernels, the use of this DKMS
  should be obsoleted. Same applies to Disco/Eoan/Focal.
