ESP8266Interface::connect() checks the exact return value from
the underlying ESP8266::connect() call.
Increased timeout for network-wifi greentea tests to 6 minutes.
With TCP it's desirable that SIGIO wakes up the application to check
if there is buffer space space available on the mode. With UDP the
behavior is not acceptable as we don't know if the other endpoint is
there as connection establishment is missing. Hence buffers might
stay full forever.
As part of the ESP8266 connect sequence, ESP8266Interface::connect,
a software reset is performed. If the ESP8266 had been connected
previously then the ESP8266 will sometimes send a "WIFI DISCONNECT" OOB
message before performing the software reset. This causes the
ESP8266::_oob_connection_status to change its state (_conn_status) from
NSAPI_STATUS_DISCONNECTED to NSAPI_STATUS_CONNECTING. This causes
ESP8266Interface::_startup, called later in the boot seqeunce, to skip
ESP8266::startup. Without this call socket mux mode (CIPMUX=1) is never
enabled and all send commands using this format fail with a "Link Type"
error.
This patch fixes that problem by unconditionally calling
ESP8266::startup as part of the ESP8266 connect sequence.
"ns_types.h" results in build failure when networking feature is ignored with
.mbedignored. ESP8266 component should be enabled only when NSAPI is present.
