The BNX2X poll mode driver library (**librte_pmd_bnx2x**) implements support
for **QLogic 578xx** 10/20 Gbps family of adapters as well as their virtual
functions (VF) in SR-IOV context. It is supported on several standard Linux
distros like Red Hat 7.x and SLES12 OS. It is compile-tested under FreeBSD OS.

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.
- 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.
- 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.
- 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.
