ecab77654a ports/unix/check: Ignore error from fail_* macros
Usage of fail_if/fail_unless macros with a message results in a

63fb3721ef ports/unix/check: Split depfiles for faster build
Having just one depfile (.depend) means it has to be fully regenerated
on every change, and it can't be done in parallel.

After this change the rebuild time after touching a single test file has
gone from 5.0 to 0.9 seconds. (make -j12)

Build of tests from clean has gone from 8.1 to 5.5s.

We could go even further and have one depfile per c-file, but this felt
like a simple first step giving a nice improvement.

d1fc5c2ec4 PPP: add one more timer to PPP_NUM_TIMEOUTS_PER_PCB for late authentication
Authentication timer might still be running when entering network phase
for any necessary rechallenge, mostly for PPP server support.

Update the detailed analysis of simultaneously running PPP timers
taking into account the authentication timer that might still be
running and chose to increase the base number to 2 instead of
adding more unnecessary complexity.

9a9d92a59e PPP, PAP: cancel PAP timeout when authentication succeed or fail
upap_timeout is not currently stopped on authentication success or

in a high pace because even if the timeout callback have a sanity
check against the PAP state the session can be restarted and be
back in the valid state before the timeout callback is actually
called.

c18a8dc9cc PPP, PPPoS: Remove useless cast from pppos_output_append() and pppos_output_last()

b2d1fc119d PPP, PPPoS: Use const void* instead of u8_t* in pppos_output_cb_fn()
There is no good reason why this function should take a non-const
pointer, as the output callback should never modify what lwIP gives it.
While changing that also switch to a more generic `void*` instead of
"byte".

the need of having to coalesce the PBUF chain before PPP processes
control packets.

e801307738 PPP: set mtu6 too when setting PPP netif MTU
PPP peer can negotiate its MRU, therefore we don't know the MTU we are
going to use before starting PPP. This is an issue because netif_add
function assume that the netif init callback function will set the MTU,
netif_add will then copy mtu to mtu6. We have then to update mtu6 each
time we update mtu to keep them in sync. Doing so is fine because PPP
netif MTU is only updated when the netif is in link down state.

a39ce0f53b PPP, PPPoS: drop input packets much bigger than our MRU
Our current HDLC decoder does not protect against starving the Rx
PBUF POOL for one packet, most likely due to received garbage on
the serial port.

Prevent starving the Rx pool by checking incoming packets length
against PPP_MRU with a 10% margin because we only want to avoid
filling all PBUFs with garbage, we don't have to be pedantic.

Fixes bug #58441: Invalid PPP data accumulates forever.

51c6548631 PPP: allow negotiating MRU with PPP_MRU config option
PPP_MRU is now free to be used for what it should have been. Now using
it at PPP init stage to set the wanted MRU value, triggering a MRU
negotiation at the LCP phase.

I doubt anyone needs it anyway, but, well, at least it is fixed and the
MRU/MTU config mess is cleaned.

And while we are at it, better document PPP MRU config values.
