* Add optimised constexpr default constructor. Default construction
was previously by a heavyweight defaulted `nsapi_addr_t` parameter.
* Remove deprecated resolving constructor.
* Take `nsapi_addr_t` inputs by constant reference rather than value.
* Inline the trivial getters and setters.
* Use `unique_ptr` to manage the text buffer.
* Make `operator bool` explicit.
* Optimise some methods.
* Update to C++11 style (default initialisers, nullptr etc)
* Optimise clearing by adding `nullptr` overload. This overload means
`Callback(NULL)` or `Callback(0)` will no longer work; users must
use `Callback(nullptr)` or `Callback()`.
* Optimise clearing by not clearing storage - increases code size of
comparison, but that is extremely rare.
* Reduce ROM used by trivial functors - share copy/destroy code.
* Config option to force trivial functors - major ROM saving by
eliminating the "operations" table.
* Config option to eliminate comparison altogether - minor ROM saving by
eliminating zero padding.
* Conform more to `std::function` API.
- PHY default configuration can be changed
- AutoNegotiation
- Speed
- DuplexMode
- PHY register offset can be updated depending on chosen PHY
All unused parameters are cleaned.
Previous change that removed string-based APIs missed
`NetworkStackWrapper::get_ip_address`. Remove string-based method (which
is not overriding anything in `NetworkStack`) and add missing binary
form to implement `NetworkStack::get_ip_address`.
The rather fiddly `nsapi_create_stack` template + overloads used during
socket formation don't inline their core, which is the identity operation
for `NetworkStack *` itself. Make code generation easier by having that
core be inline.
DISCO_F769NI EMAC driver may return ethernet packet with illegal
length when driver is under heavy load. In one case, the received
bytes indicate frame length of 53 bytes but advertised data length
was 65518 bytes. In another case EMAC driver variable
`EthHandle.RxFrameInfos.length` contained value 0xFFFF FFFC.
As a work-around accept only 1-1500 bytes long ethernet packets.
ARCH_MAX board uses 0x01 as PHY address, different from other NUCLEO STM32 boards. To faciliate change of PHY address of customized boards, a configuration entry eth-phyaddr was added and can be overriden as needed in mbed_app.json by adding "stm32-emac.eth-phyaddr": X. Macro ETH_ARCH_PHY_ADDRESS was also renamed to ETH_PHY_ADDRESS, because it is not only used by ARCH_MAX board but also other boards.
Issue: udp_sendto() Fails for multicast IPV6 packet when interface is switched from SoftAP to STA mode.
When SoftAP start is called, add_ethernet_interface() will be called internally to add interface details into netif_list.
When switching from SoftAP to STA mode, add_ethernet_interface() will be called again to append the interace details into netif_list.
When udp_sendto() is called, ip6_route() will return interface as NULL since it consider device as single interface.
Fix: SoftAP mode Stop, call remove_ethernet_interface() to remove the interface from the netif_list.
