+FM10K Poll Mode Driver
+======================
+
+The FM10K poll mode driver library provides support for the Intel FM10000
+(FM10K) family of 40GbE/100GbE adapters.
+
+
+Limitations
+-----------
+
+
+Switch manager
+~~~~~~~~~~~~~~
+
+The Intel FM10000 family of NICs integrate a hardware switch and multiple host
+interfaces. The FM10000 PMD driver only manages host interfaces. For the
+switch component another switch driver has to be loaded prior to to the
+FM10000 PMD driver.  The switch driver can be acquired for Intel support or
+from the `Match Interface <https://github.com/match-interface>`_ project.
+Only Testpoint is validated with DPDK, the latest version that has been
+validated with DPDK2.2 is 4.1.6.
+
+CRC striping
+~~~~~~~~~~~~
+
+The FM10000 family of NICs strip the CRC for every packets coming into the
+host interface.  So, CRC will be stripped even when the
+``rxmode.hw_strip_crc`` member is set to 0 in ``struct rte_eth_conf``.
+
+
+Maximum packet length
+~~~~~~~~~~~~~~~~~~~~~
+
+The FM10000 family of NICS support a maximum of a 15K jumbo frame. The value
+is fixed and cannot be changed. So, even when the ``rxmode.max_rx_pkt_len``
+member of ``struct rte_eth_conf`` is set to a value lower than 15364, frames
+up to 15364 bytes can still reach the host interface.
