Dear Maintainer,



   * What led up to the situation?
   installing and configuring dpdk, 5.10 and 4.19 provide ib_uverbs and
   mlx4_ib but 5.4 does not.

   * What exactly did you do (or not do) that was effective (or
     ineffective)?
   updating to 5.10 fixes the issue
   * What was the outcome of this action?
   dpdk installs and works, it does not 'out of the box' for 5.4

box' experience? That way we would be able to reproduce this (hopefully).

If you don't mind me asking: What is the use case?

Source-Version: 5.6.14-1

You mention it above, that it works with 5.10 based kernel.
5.4.8-1~bpo10+1 is not anymore something supported in Debian, current
will be 5.10.103-1~bpo10+1 for backport kernel in buster.

In fact for the clound kernels the  INFINIBAND configs for
HyperV/Azure were enabled in 5.6.14-1 (cf. #958300).

Salvatore
