- Added non-blocking DNS interface to network interface and
network stack.
- Added caching of DNS replies.
- Added a network stack function to get DNS addresses from stack.
- Added call and call_in hooks to onboard network stack to
allow calling functions from onboard stack context.
- Added support to call and call_in functions to LWIP and
Nanostack.
- Disabled LWIP DNS translator with the exception of DNS
address storage used in DNS address get.
Implementation of unified EMAC driver for Renesas mbed boards
Based on the driver so far, Renesas implemented the emac driver for GR-PEACH and VK-RZ/A1H.
The mainly changes is below.
- Add the connection part with LWIP according to the unified emac specification.
- Add three new multicast functions(add, remove, set_all).
The Greentea test netsocket and emac test passed.
Just checking "does the chip have an EMAC" doesn't work - there are
targets using those chips which do not have an Ethernet connector and
don't provide the necessary surrounding infrastructure (eg DISCO_F429ZI,
not providing the board emac config call, and HEXIWEAR not providing PHY
info).
Make the targets that actually do want EMAC define their own local
Freescale_EMAC and STM_EMAC labels, and move the drivers into
the corresponding TARGET_ directories, removing the #ifdefs.
Checking DEVICE_EMAC is problematic - particularly for the Odin W2 where
apps have been shutting this off to disable the Wi-fi interface.
Make drivers check a locally-relevant flag instead, pending new
thoughts on how to achieve application/test-relevant flagging for
XXX:get_default_instance() being provided by a system.
However that is achieved, drivers do require a flag set purely by the
target - they mustn't be tripped up by an add-on module providing itself
as the system's default EMAC.
Make Nanostack an OnboardNetworkInterface, implementing
add_ethernet_interface so it can use EMAC drivers.
Can now be used via EthernetInterface, and be the system's default
network stack.
Legacy support for NanostackEthernetInterface retained. Some
restructuring of mesh interface code to fit into the
OnboardNetworkStack:::Interface system.
I would like to restrict these to devices with "device_has": "EMAC", but
the framework doesn't currently permit that. Revisit as more drivers
are EMAC-enabled or if the framework changes.
Make ETHERNET configuration the default if DEVICE_EMAC is present,
instead of if FEATURE_LWIP is present.
This limits it to targets which have been ported to the new EMAC API.
Add LWIP feature to JSON config, as in principle the targets shouldn't
be adding it themselves. Opens scope to having Nanostack-based tests.
Disable tests for the Realtek and Wifi drivers that aren't ported yet.
As we've introduced virtual inheritance to support EMACInterface, we can
no longer use C-style casts or static_cast to downcast from
NetworkInterface to more specific types. RTTI is disabled in the
toolchains, so dynamic_cast is unavailables.
Add virtual downcast methods to permit conversions to the 6 derived
classes. Probably only needed for EMACInterface, WiFiInterface and
EthInterface, but handles the set.
* Since mbed does not overwrite itself, make the flashing routines run out of flash by default
* Report a writeable size of 4 bytes (previously erroneously reported a full eraseable page as the minimum write size)
* IRQ handling got updated previously to a non-functional state when both callbacks were registered (it'd fire a fall callback for both rise and fall events). With this update, that faulty behaviour is corrected. Due to delays between the detection of the edge and the handling of the interrupt (and the fact that information about which edge you received on the pin is not stored anywhere), there is no way to be absolutely sure which edge got triggered on the pin. Therefore, we make a best-guess effort by looking at the pin state at the time of IRQ handling, and fire a callback as if that was the end state of the event. This will usually work out fine, except in cases were the signal is toggling faster than the IRQ handler's response time. In that case, a user won't get both callbacks (as expected for a pulse), but only the last event.
* Stripped some dead code.
