Thanks. And so are WX and WG two different version of FPGA?

Hi all,
I need to use some N310s with White Rabbit (WR) and I have some question:
Why in "Features" here (N310): link
<https://www.ettus.com/all-products/usrp-n310/> there is no White
Rabbit, while here (N321): link
<https://www.ettus.com/all-products/usrp-n321/> yes? Here: link
<https://kb.ettus.com/Using_Ethernet-Based_Synchronization_on_the_USRP%E2%84%A2_N3xx_Devices>
the link talk about the N3xx generic. So, seems to be an error on the
website?
Here link
<https://kb.ettus.com/Using_Ethernet-Based_Synchronization_on_the_USRP%E2%84%A2_N3xx_Devices>
I find: "The USRP N3xx use the SFP+ 0 port for White Rabbit and SFP+
1 port for IQ streaming. This port configuration requires the White
Rabbit “WX” FPGA bitfile".
Here link
<https://kb.ettus.com/USRP_N300/N310/N320/N321_Getting_Started_Guide#Dual_10Gb_Streaming_SFP_Ports_0.2F1>
says that all possible FPGA are XG, HG and WG. How about the WX? Is
WG? Is the same? Was a typo?
Again, same link, says that "The XG FPGA image must be loaded for SFP
Port 0 to operate at 10 Gb speeds. If the HG image is loaded, the
port will be unresponsive at 10 Gb speeds". How about the WG?
It is sure that White Rabbit can work with the N310? If the WX FPGA
it's flashed, teoretically I can use one SFP+ port for WR and one
SFP+ port for I/Q streaming. I need to be sure that the speed of the
second port is 10 GbE (and not reduced to 1 GbE).
Thanks in advance
Giuseppe

According to my contacts, the N310_WX indeed puts WR on sfp0, and
10GiGe on sfp1.
