Every commit builds with -Dwerror=true for the touched drivers (except mvneta/mvpp2, no musdk) and the touched apps and examples. check-doc-vs-code.sh full mode is clean at every commit. v2 items addressed: incremental mode now checks the changed drivers (adding "VMDq = Y" to mlx5.ini is reported with a trusted commit), intel directory detection (03/13), Cc: stable on 06, 09 and 11, RSS commit message (12/13). Shared-directory rte_flow checks behave as described: a doc-only item in cnxk_vf.ini is reported, and an item missing from every ice doc is reported against ice. One item left. Patch 12/13 ethdev: check RSS availability Warning: the release note still says RSS mode is always rejected. The code rejects it only with more than one Rx queue and ignores it with one: * RSS mode (Rx ``RTE_ETH_MQ_RX_RSS_FLAG``) is rejected with more than one Rx queue if the driver reports no ``flow_type_rss_offloads``, and ignored with a single Rx queue.
