How many Ethernet Interfaces on FWA-1010VC will be detected in OS?

Purpose:

Because there's a soho switch on FWA-1010VC,  how to identify all those Ethernet ports on this machine would be the frequently asked question.  This article will introduce those physical interfaces in detail.

Target Audience:

All users which is using Advantech FWA-1010VC series.

Use Cases:

Due to SoHo switch design in FWA-1010VC ,  the OS will have interfaces less than the label on front panel.  

In OS :  User should recognize 4 I354 devices from PCI list

00:14.0 Ethernet controller: Intel Corporation Ethernet Connection I354 (rev 03)
00:14.1 Ethernet controller: Intel Corporation Ethernet Connection I354 1.0 GbE Backplane (rev 03)
00:14.2 Ethernet controller: Intel Corporation Ethernet Connection I354 (rev 03)
00:14.3 Ethernet controller: Intel Corporation Ethernet Connection I354 (rev 03)

As mentioned above, it appears 4 in total is expected  =   2 for dual media ports (note fiber or copper only) ,  1 connect to SoHo switch ,  1 for port 6 (rightest one on front panel)

The labels on the box :

label 0 : Dual Media 1st port  (eth0 in block diagram)
label 1 :  Dual Media 2nd port  (eth2 in block diagram)
label 2 - 5 : Port for SoHo switch (eth1 the rightest 4 ports from 88E6141)
label 6 :  generic Ethernet port (eth3 in block diagram)

## Check in OS , User will find the port which connect to SoHo switch is always in "UP" Status, even though front panel port 2 ~ 5 has no cable connected
