The mellanox and broadcom drivers contained a "dynamic interrupt
moderation" feature (as early as v5.0) which was broken out into a
common kernel library 'DIMLIB' in lib/dim/ circa mainline v5.2.
Backported drivers may now need DIMLIB to be available in pre-5.2
kernels (specifically, the latest upstream version of
Pull req's to follow ...
Apply all the mainline commits from v5.2 which extract DIMLIB from
mellanox/broadcom and wire those drivers to use DIMLIB (plus a few
later DIMLIB fixes). I.e. make Disco work the same as > 5.2 kernels;
no significant functional change to those drivers.
For Bionic and Xenial:
Import the lib/dim/ directory from mainline (plus a couple porting
prerequisites), but do *not* make mellanox/broadcom use it. I.e. no
functional change at all.
