[dpdk-stable] patch 'doc: add i40e limitation for flow director' has been queued to stable release 19.11.3

[luca.boccassi at gmail.com]

Hi,

FYI, your patch has been queued to stable release 19.11.3

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 05/21/20. So please
shout if anyone has objections.

Also note that after the patch there's a diff of the upstream commit vs the
patch applied to the branch. This will indicate if there was any rebasing
needed to apply to the stable branch. If there were code changes for rebasing
(ie: not only metadata diffs), please double check that the rebase was
correctly done.

Thanks.

Luca Boccassi

+Input set requirement of each pctype for FDIR
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Each PCTYPE can only have one specific FDIR input set at one time.
+For example, if creating 2 rte_flow rules with different input set for one PCTYPE,
+it will fail and return the info "Conflict with the first rule's input set",
+which means the current rule's input set conflicts with the first rule's.
+Remove the first rule if want to change the input set of the PCTYPE.
