Enum pl_sock_interfaces contains the list of available network interfaces. The EM1202 and EM1202W platforms differ in that the EM1202W has the W-Fi interface (requires an external GA1000 add-on module), while the EM1202 does not, and the pl_sock_interfaces reflects this.

EM1202 platform

0- PL_SOCK_INTERFACE_NULL:                        Null (empty) interface.

1- PL_SOCK_INTERFACE_NET (default):                Ethernet interface.

3- PL_SOCK_INTERFACE_PPP:                        PPP interface.

4- PL_SOCK_INTERFACE_PPPOE:                        PPPoE interface.

EM1202W platform

0- PL_SOCK_INTERFACE_NULL:                        Null (empty) interface.

1- PL_SOCK_INTERFACE_NET (default):                Ethernet interface.

2- PL_SOCK_INTERFACE_WLN:                        Wi-Fi interface.

3- PL_SOCK_INTERFACE_PPP:                        PPP interface.

4- PL_SOCK_INTERFACE_PPPOE:                        PPPoE interface.
