=============================
The MLX4 poll mode driver library (**librte_pmd_mlx4**) implements support
-for **Mellanox ConnectX-3 EN** 10/40 Gbps adapters as well as their virtual
-functions (VF) in SR-IOV context.
+for **Mellanox ConnectX-3** and **Mellanox ConnectX-3 Pro** 10/40 Gbps adapters
+as well as their virtual functions (VF) in SR-IOV context.
Information and documentation about this family of adapters can be found on
the `Mellanox website <http://www.mellanox.com>`_. Help is also provided by
Compiling librte_pmd_mlx4 causes DPDK to be linked against libibverbs.
Features
----------
+--------
- RSS, also known as RCA, is supported. In this mode the number of
configured RX queues must be a power of two.
- RSS always includes L3 (IPv4/IPv6) and L4 (UDP/TCP). They cannot be
dissociated.
- Hardware counters are not implemented (they are software counters).
-- Secondary process RX is not supported
+- Secondary process RX is not supported.

The MLX5 poll mode driver library (**librte_pmd_mlx5**) provides support for

+**Mellanox ConnectX-4** and **Mellanox ConnectX-4 Lx** families of
10/25/40/50/100 Gb/s adapters as well as their virtual functions (VF) in
SR-IOV context.

+* **mlx4: Fixed scattered Tx with too many segments.**
* **mlx4: Fixed memory registration for indirect mbuf data.**
PF reset in host side. The workaround is to avoid triggering any PF reset
events/requests on host side.
+* 100G link report support is missing.
+
* **Mellanox PMDs (mlx4 & mlx5):**
- * PMDs do not support DPDK integrated shared library.
+ * PMDs do not support CONFIG_RTE_BUILD_COMBINE_LIBS and
+ CONFIG_RTE_BUILD_SHARED_LIB simultaneously.
* There is performance degradation for small packets when PMD
is compiled with SGE_WR_N = 4 compared to the performance when SGE_WR_N = 1.
* When a Multicast or Broadcast packet is sent to the SR-IOV mlx4 VF,
it is returned back to the port.
+ * PMDs report "bad" L4 checksum when IP packet is received.
+
+ * mlx5 PMD reports "bad" checksum although the packet has "good" checksum.
+ Will be fixed in upcoming MLNX_OFED release.
