Co-existence considerations
---------------------------
-- BCM578xx being a CNA can have both NIC and Storage personalities.
- However, coexistence with storage protocol drivers (cnic, bnx2fc and
- bnx2fi) is not supported on the same adapter. So storage personality
- has to be disabled on that adapter when used in DPDK applications.
-
-- For SR-IOV case, bnx2x PMD will be used to bind to SR-IOV VF device and
- Linux native kernel driver (bnx2x) will be attached to SR-IOV PF.
-
+- QLogic 578xx CNAs support Ethernet, iSCSI and FCoE functionalities.
+ These functionalities are supported using QLogic Linux kernel
+ drivers bnx2x, cnic, bnx2i and bnx2fc. DPDK is supported on these
+ adapters using bnx2x PMD.
+
+- When SR-IOV is not enabled on the adapter,
+ QLogic Linux kernel drivers (bnx2x, cnic, bnx2i and bnx2fc) and bnx2x
+ PMD can’t be attached to different PFs on a given QLogic 578xx
+ adapter.
+ A given adapter needs to be completely used by DPDK or Linux drivers.
+ Before binding DPDK driver to one or more PFs on the adapter,
+ please make sure to unbind Linux drivers from all PFs of the adapter.
+ If there are multiple adapters on the system, one or more adapters
+ can be used by DPDK driver completely and other adapters can be used
+ by Linux drivers completely.
+
+- When SR-IOV is enabled on the adapter,
+ Linux kernel drivers (bnx2x, cnic, bnx2i and bnx2fc) can be bound
+ to the PFs of a given adapter and either bnx2x PMD or Linux drivers
+ bnx2x can be bound to the VFs of the adapter.
