EMAC changes broke PPP glue - fix it up. In particular, PPP steals
the netif->state pointer, so we can't use it as a back pointer to
our LWIP::Interface.
There is a configuration problem with UBLOX_C027 cellular because of missing
LWIP memory configuration for the target.
Added configuration for LPC1768, LPC4088, LPC4088_DM targets and changed
NXP to more specific LPC546XX.
- Set network stack to store event queue so that mbed::mbed_event_queue() call
is not needed every time call_in() is called
- Added dns state variables and enum (states are: created, initiated and cancelled)
- Corrected DNS response handling so that if DNS server returns that host name is
unknown the DNS query is not tried again
- Reorder mutexes in nsapi_dns_query_multiple_async()
- Created nsapi_dns_query_async_initiate_next() function to initiate the next
DNS query from the queue after delete of previous query
- Added dsn_timer_running variable to supervise DNS timer start/stop
- Changed cancel function to only mark query as deleted and moved deletion
to timer function. This allows to run socket close on DNS thread
- Added new nsapi error NSAPI_ERROR_TIMEOUT for DNS (and other) timeouts
General stability improvements are performed.
A flag is added if a Class C RX2 window is open.
We shouldn't open it again if its already opened.
TX_CRYPTO_ERROR is renamed to CRYPTO_ERROR.
Keeping TX_CRYPTO_ERROR for backwards compatibility.
In Class C, rx timeout does not take place for RX2 windows, so if we have
not received anything, we would be retrying but if the no. of retries are
maxed out, and we have not recieved anything yet, we need a mechanism to
tell the upper layer that this has happened.
rx_abort() was sort of dead code as it was doing essentially nothing.
It might have actually meddled with the state machine if it was hit by
invoking on_ack_timeout_timer_event().
State machine and corresponding processors now take care of the ack timeout,
retries and all other bits, so we don't need abort_rx().
MCPS confirmation should be filled with the current number of retries
if the ack is not recieved for a CONFIRMED message.
Ack retry number needs to be incremented after the retry is made not before
that.
A few traces are added at the crucial junctions of the code just to tally with
the conceptual flow for debug purposes.
Application can use cancel_sending() API to stop any outstanding, outgoing
transmission (a TX which is not already queued for transmission). This can
potentially enable use cases where the application could cancel a transmission
and go to sleep if the backoff period is long enough rather than waiting for
the transmission to happen.
This API enables the application to get hold of remaining time after which
the transmission will take place. User can query the backoff time whenever
there is a packet in the TX pipe. If the event for the backoff expiry is
already queued, the stack does not provide backoff metadata.
An API is added to fetch any meta-data available after a succesful
transmission. The stack will make the meta data available after the
TX interrupt is processed. User can get the tx meta data after receiving
TX_DONE event.
