The compilation was broken by a couple of recent blind, unverified changes to up_wpcap.c.  Most were introduced with commit: 8ce0ff5ce4 with this change:

Which is where the collision error is introduced since up_wpcap.c includes winsock2.h already.  There were additional problems introduced to the file by other changes:

- A malformed syslog() call was added
- Some issues with netdriver_setmacaddr()

c47ad0c909 arch/sim: Add host timer to oneshot timer logic
## Summary of Changes

Add a host timer that generates periodic signals and sends SIGALRM to
the process that runs the NuttX simulation. This logic is integrated as
part of the existing NuttX oneshot timer. The host timer installs an
irq handler which is expected to run every CONFIG_USEC_PER_TICK .

a9830254cf SIM in MacOS: make MacOS link process same with Linux
1. There is difference about symbol replace on nuttx-names.in
   between MacOS & Linux
2. For MacOS, if open '-fvisibility=hidden' and adjust nuttx-names.in,
   it will meet symbol link-back-to-nuttx error.
3. Make the MacOS replace behaviour, same with Linux

Note:
MacOS should install objcopy with command:
$ brew install binutils
$ export PATH=$PATH:/usr/local/opt/binutils/bin

already check in to cibuild.sh

3d1159007f Remove extra application of EXTRAFLAGS and KDEFINE and the arch-level
EXTRAFLAGS is already applied to *FLAGS in board's Make.defs (and
it applies to whole build, not just arch-code). EXTRAFLAGS is passed
around each make call to the complete build.

KDEFINE is already added to EXTRAFLAGS in main Makefile so no need
to add it again in arch-level Makefile

2cfb239a87 arch/sim/src/nuttx-names.in: only host code need replace if -fvisibility=hidden
After previous commit, add -fvisibility=hidden, we don't need
worry about depended libxx.so callback to nuttx symbol in SIM.

So most of the symbol in nuttx-names.in can be remove.

But we still need some symbol replacement for host code.
Host code should call host API if access HOST sth, for example:
open, close, accept, printf...

5beb32bf0b arch/sim: Use pthread_cond for signalling CPU initialisation done
## Summary of changes

On OSX with CONFIG_SMP=y the semaphore which notifies that the CPU is
initialised, is not created and the up_cpu_start() returns with error
from sem_init(). This patch fixes the problem by using pthread_cond_t
signalling mechanism which is supported on Mac.

6d69439f58 Call xxx_timer_initialize from clock subsystem
Call xxx_timer_initialize from clock subsystem to make timer ready for use as soon as possiblei and revert the workaround:

commit 0863e771a9
Author: Gregory Nutt <gnutt@nuttx.org>
Date:   Fri Apr 26 07:24:57 2019 -0600

    Revert "sched/clock/clock_initialize.c:  clock_inittime() needs to be done with CONFIG_SCHED_TICKLESS and clock_initialize should skip clock_inittime() for external RTC case since the RTC isn't ready yet."

    This reverts commit 2bc709d4b9.

    Commit 2bc709d4b9 was intended to handle the case where up_timer_gettime may not start from zero case.  However, this change has the side-effect of breaking every implementation of tickless mode:  After this change the tickless timer structures are used before they are initialized in clock_inittime().  Initialization happens later when up_initialize is called() when arm_timer_initialize().

    Since the tickless mode timer is very special, one solution might be to

    1. Rename xxx_timer_initialize to up_timer_initialize
    2  Move up_timer_initialize to include/nuttx/arch.h
    3.  Call it from clock subsystem instead up_initialize

    Basically, this change make timer initialization almost same as rtc initialization(up_rtc_initialize).

    For now, however, we just need to revert the change.

f00569816f Fix a few errors concerning use of section block comments in .c files: (#95)
1. No .c file should include a "Public Types" section.  Only a header file can define a public type.  A .c file can only define a private type.  Several files contained private type definitions.  The section that they were defined in, however, was incorrectly named "Public Types."  Those were easilty changed to "Private Types" which is what they are.

2. No .c file should include a "Public Function Prototypes" section.  All global function prototypes should be provided via a header file and never declared with a .c file.

For No. 2, I corrected as many cases as was reasonable for the time that I had available.  But there are still a dozen or so .c files that declare "Public Function Prototypes" within a .c file.  This is bad programming style.  These declarations should all be moved to the proper header files.

87cf5c58ae Correct some problems with network timed events when there are multiple network devices in the configuration.
Squashed commit of the following:

Author: Gregory Nutt <gnutt@nuttx.org>

    Ran nxstyle against many of the affected files.  But this job was too big for today.  Many of the network drivers under arch are highly non-compiant and generate many, many faults from nxstyle.  Those will have to be visited again another day.

Author: Xiang Xiao <xiaoxiang@xiaomi.com>

    This effects all network drivers as well as timing related portions of net/: devif_poll_tcp_timer shouldn't be skipped in the multiple card case.  devif_timer will be called multiple time in one period if the multiple card exist, the elapsed time calculated for the first callback is right, but the flowing callback in the same period is wrong(very short) because the global variable g_polltimer is used in the calculation.  So let's pass the delay time to devif_timer and remove g_polltimer.

Move boards to boards folder

* boards: rename configs folder to boards

    This is the proposed layout after the change:

    boards: - folder containing board folders
            <board>: - name of each board
                    drivers: - extra drivers specific for platform
                    include: - header files for the boars
                    scripts: - extra scripts specific for platform
                        src: - board specific code
                      tools: - extra tools specific for platform
                    <config>: - board specific configuration(s)

    Note:
    <xxx> names are dependent on platform

    This is a logical change to aim to the arch layout but this is a
    huge change it should be done in several steps to lower the risk.

22cd0d47fa This commit attempts remove some long standard confusion in naming and some actual problems that result from the naming confusion. The basic problem is the standard MTU does not include the size of the Ethernet header. For clarity, I changed the naming of most things called MTU to PKTSIZE. For example, CONFIG_NET_ETH_MTU is now CONFIG_NET_ETH_PKTSIZE.
This makes the user interface a little hostile.  People thing of an MTU of 1500 bytes, but the corresponding packet is really 1514 bytes (including the 14 byte Ethernet header).  A more friendly solution would configure the MTU (as before), but then derive the packet buffer size by adding the MAC header length.  Instead, we define the packet buffer size then derive the MTU.

The MTU is not common currency in networking.  On the wire, the only real issue is the MSS which is derived from MTU by subtracting the IP header and TCP header sizes (for the case of TCP).  Now it is derived for the PKTSIZE by subtracting the IP header, the TCP header, and the MAC header sizes.  So we should be all good and without the recurring 14 byte error in MTU's and MSS's.

Squashed commit of the following:

    Trivial update to fix some spacing issues.
    net/: Rename several macros containing _MTU to _PKTSIZE.
    net/: Rename CONFIG_NET_SLIP_MTU to CONFIG_NET_SLIP_PKTSIZE and similarly for CONFIG_NET_TUN_MTU.  These are not the MTU which does not include the size of the link layer header.  These are the full size of the packet buffer memory (minus any GUARD bytes).
    net/: Rename CONFIG_NET_6LOWPAN_MTU to CONFIG_NET_6LOWPAN_PKTSIZE and similarly for CONFIG_NET_TUN_MTU.  These are not the MTU which does not include the size of the link layer header.  These are the full size of the packet buffer memory (minus any GUARD bytes).
    net/: Rename CONFIG_NET_ETH_MTU to CONFIG_NET_ETH_PKTSIZE.  This is not the MTU which does not include the size of the link layer header.  This is the full size of the packet buffer memory (minus any GUARD bytes).
    net/: Rename the file d_mtu in the network driver structure to d_pktsize.  That value saved there is not the MTU.  The packetsize is the memory large enough to hold the maximum packet PLUS the size of the link layer header.  The MTU does not include the link layer header.

9568600ab1 Squashed commit of the following:
This commit backs out most of commit b4747286b1.  That change was added because sem_wait() would sometimes cause cancellation points inappropriated.  But with these recent changes, nxsem_wait() is used instead and it is not a cancellation point.

    In the OS, all calls to sem_wait() changed to nxsem_wait().  nxsem_wait() does not return errors via errno so each place where nxsem_wait() is now called must not examine the errno variable.

    In all OS functions (not libraries), change sem_wait() to nxsem_wait().  This will prevent the OS from creating bogus cancellation points and from modifying the per-task errno variable.

    sched/semaphore:  Add the function nxsem_wait().  This is a new internal OS interface.  It is functionally equivalent to sem_wait() except that (1) it is not a cancellation point, and (2) it does not set the per-thread errno value on return.
