Important Notes:
----------------

There are two traffic issues related to the FCoE configurations. There is no feasible fix for both issues
in a single driver version since the fix will break one or the other.

First Issue: Dropping traffic when non-FCoE Ether-Type traffic is configured with FCoE User Priority.
   The fix is in driver version 4.4.1 and 4.5.1, but this fix introduces a bug for the second issue,
   which is in driver version 4.5.1

Second Issue: FCoE packets are dropped when FCoE and port VLAN tagging are configured in the environment
   The fix is in driver version 4.5.2, which basically reverts the change that was intended to fix the first issue.

   Please look at the VMware Knowledge Base (KB) for more info
   https://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2149835

Therefore, please use driver version
- 4.4.1 or 4.5.1 to avoid the first issue
- 4.5.2 or older versions, which is mentioned in the KB 2149835, to avoid the second issue


New Features:
-------------
- Added a single speed (1Gig only) support for 88E1512/88E1514 PHY for x552 family device 

New Hardware Supported:
-----------------------
- Added new x552 family device that supports a single 1Gig speed only 


Bug Fixes:
----------
- Fixed FCoE packets dropped when FCoE and port VLAN tagging are configured
  Please look at the Important Notes section for more info


Known Issues and Workarounds:
-----------------------------
- Dropping traffic when non-FCoE Ether-Type traffic is configured with FCoE User Priority
  Please look at the Important Notes section for more info


Command Line Parameters:
------------------------

Use esxcli, vsish, or esxcfg-* to set or get the driver information, for example:

- Get the driver info
  esxcli network  nic get -n vmnic1

- Get an uplink stats
  esxcli network nic stats get -n vmnic1

- Get the Netqueue stats
