+- ``Support multiple driver`` (default ``disable``)
+
+ There was a multiple driver support issue during use of 700 series Ethernet
+ Adapter with both Linux kernel and DPDK PMD. To fix this issue, ``devargs``
+ parameter ``support-multi-driver`` is introduced, for example::
+
+ -w 84:00.0,support-multi-driver=1
+
+ With the above configuration, DPDK PMD will not change global registers, and
+ will switch PF interrupt from IntN to Int0 to avoid interrupt conflict between
+ DPDK and Linux Kernel.
