-PF requires a specific link, ``/lib/firmware/netronome/nic_dpdk_default.nffw``,
-which should be created automatically with Netronome's Agilio products
-installation.
+PF looks for a firmware file in this order:
+
+ 1) First try to find a firmware image specific for this device using the
+ NFP serial number:
+
+ serial-00-15-4d-12-20-65-10-ff.nffw
+
+ 2) Then try the PCI name:
+
+ pci-0000:04:00.0.nffw
+
+ 3) Finally try the card type and media:
+
+ nic_AMDA0099-0001_2x25.nffw
+
+Netronome's software packages install firmware files under ``/lib/firmware/netronome``
+to support all the Netronome's SmartNICs and different firmware applications.
+This is usually done using file names based on SmartNIC type and media and with a
+directory per firmware application. Options 1 and 2 for firmware filenames allow
+more than one SmartNIC, same type of SmartNIC or different ones, and to upload a
+different firmware to each SmartNIC.
