+.Sh UPDATING FIRMWARE
+Adapter firmware updates are persistent.
+
+Firmware can be updated by following the steps below:
+.nf
+ 1) Copy the below code to a Makefile
+  ".KMOD=elxflash
+   FIRMWS=imagename.ufi:elxflash
+   .include <bsd.kmod.mk>"
+ 2) Replace imagename in above with UFI file name.
+ 3) Copy Makefile and UFI to a directory
+ 4) Execute make & copy generated elxflash.ko to /lib/modules
+ 5) sysctl dev.oce.<if_id>.fw_upgrade=elxflash
+ 6) Reboot the machine.
+
+In case of issues with supplied UFI, flashing fails with one
+of the below errors.
+ 1) "Invalid BE3 firmware image"
+ 2) "Invalid Cookie. Firmware image corrupted ?"
+ 3) "cmd to write to flash rom failed."
