+Using DPDK's AF_XDP PMD driver
+------------------------------
+Another way to use AF_XDP is to enable DPDK and use DPDK's AF_XDP
+driver. First, enable the AF_XDP PMD config at DPDK's
+config/common_base file by::
+
+ CONFIG_RTE_LIBRTE_PMD_AF_XDP=y
+
+and recompile the DPDK source. Then, compile OVS with DPDK::
The AF_XDP pmd went in dpdk 19.05.
OVS master uses dpdk 18.11.2.

If you want to have a note in this doc in the master branch, you must
properly explain this, or users will be disappointed and complain on
the ml :-)
+1, also I think we shouldn't reference commits in the docs that
reference the dpdk-latest branch (I was burned by this before in commit
messages myself), the reason is I intend to rebase dpdk-latest on master
after the 2.12 release and as such the commit IDs will change due to
the rebase.
I'm not so sure we should even add documentation to master regarding the
AF_XDP PMD until master moves to 19.11? Possibly the 'dpdk-latest' might
be a better candidate for this doc change?

Ian
