Driver must return NSAPI_ERROR_WOULD_BLOCK if a server won't accept
data from the modem and the modem's buffers are full. In case that
socket is closed driver returns NSAPI_ERROR_CONNECTION_LOST.
The DEVICE_FOO macros are always defined (either 0 or 1).
This patch replaces any instances of a define check on a DEVICE_FOO
macro with value test instead.

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.
UDP packets are always received as OOB data. Without checking for
new OOB data with a call to "_process_oob" then recv_udp never blocks.
If a UDP packet is not available then NSAPI_ERROR_WOULD_BLOCK is
returned. This causes mbed-os's DNS handling to always fail when
flow control is enabled.
This patch fixes recv_udp by always calling "_process_oob" regardless
of if flow control is enabled. This ensures that recv_udp follows the
timeout parameter and waits for new data to arrive.
Currently there are two issues which prevent building Mbed OS with
-std=gnu++11 when using Arm Compiler 6:
* NanostackRfPhys2lp.cpp contains a narrowing conversion in a braced
initializer list
* ns_types.h includes <stdalign.h> which Arm Compiler 6 currently
does not provide
This patch fixes both issues. The first one is fixed by changing the
underlying type of the corresponding enumeration when the code is
compiled as C++11. The second issue is worked around by avoiding the
use of <stdalign.h> header for Arm Compiler versions prior to 6.12.
"ns_types.h" results in build failure when networking feature is ignored with
.mbedignored. ESP8266 component should be enabled only when NSAPI is present.
