[Bug 2019069] Re: Log messages from dpdk library overflow and is written as multiple lines causing issues for testsuite

[Christian Ehrhardt]

This always was low priority, sorry.
But the 24.11 log message macro changed and ensured to add new lines, worth a check if this is still an issue or doesn't matter for other reasons anymore these days.

Title:
  Log messages from dpdk library overflow and is written as multiple
  lines causing issues for testsuite

Status in dpdk package in Ubuntu:
  New
Status in openvswitch package in Ubuntu:
  Incomplete

Bug description:
  The Open vSwitch system testsuites make assertions based on contents
  of the ovs-vswitchd.log file.

  While attempting to enable the DPDK system tests as part of the
  autopkgtests, we found that currently the log messages from DPDK
  overflow and are written out across multiple lines.

  I find nothing obvious in OVS that causes this, so I wonder if this is
  an issue in DPDK, how we build/relate it in Ubuntu or if OVS needs to
  initialize it differently.

  Example log excerpts:
