From a89517cafe2819cbe7c64e2a0653950150910a47 Mon Sep 17 00:00:00 2001 From: Alexandru Avadanii Date: Thu, 12 May 2016 18:44:28 +0200 Subject: docs/install-instr: Add target specific cfg sect. Fuel 8.0 adds support for setting up "Offloading Modes" for target nodes. Document how this features should be used (and why/when it's necessary), and also its common limitation of not being applied during Verify Networks step (see related Fuel bug report [1]). While at it, fix minor reference to branch in git tag checkout instructions, as we'd be in detached HEAD and not on a new branch. [1] https://jira.opnfv.org/browse/FUEL-134 [Alexandru.Avadanii@enea.com] Only minor edits and prepared for upstreaming, this is mostly based on previous work from Florin.
