NuttX follows OpenGroup.org: https://pubs.opengroup.org/onlinepubs/009695399/functions/recv.html :
[EAGAIN] or [EWOULDBLOCK]
The socket's file descriptor is marked O_NONBLOCK and no data is waiting to be received; or MSG_OOB is set and no out-of-band data is available and either the socket's file descriptor is marked O_NONBLOCK or the socket does not support blocking to await out-of-band data.
ETIMEDOUT is not a valid error to be returned from recv() or recvfrom().

Commit cf5d17f795 added logic to detect #define pre-processor definitions outside of the "Pre-processor Definitions" file section. That commit was verified against numerous .c source files. But not against any .h header files.
When run against a header file, that change causes a false alarm warning like:
file:line:pos: warning: #define outside of 'Pre-processor Definitions' section
That is caused the idempotence, guard definition that must appear in the header file BEFORE the first file section.
This commit adds logic to nxstyle to ignore pre-processor definitions in header files that occur before the first file section is encountered.

Add SPWM example to test STM32L4 PWM driver low level operations.
Fix BUGs.
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.
* fix warning: format '%x' expects argument of type 'unsigned int', but argument 4 has type 'long unsigned int'
* fix warning: implicit declaration of function 'up_init_exidx'
* tools/nxstyle: Added logic to parse section headers (like Included files, Pre-processor Definitions, etc.) and to assure that the section headers are correct for the file type. Also (1) verify that #include appears only in the 'Included Files' section and that (2) #define only occurs in the Pre-processor definition section.
Right now, there are several places where that rule is not followed. I think most of these are acceptable so these failures only generate warnings, not errors. The warning means that we need to go look at the offending #define or #include and decide if it is a acceptable usage or not.
the width of all block comments. Includes a check to assure that all block
comments use the same line width.
Verified against all .c files under /sched. There were a few cosmetic changes to the coding style under /sched to account to new, correctly detected problems in the /sched files.
1.Consolidate absolute to relative timeout conversion into one place(_net_timedwait)
2.Drive the wait timeout logic by net_timedwait instead of devif_timer
This patch help us remove devif_timer(period tick) to save the power in the future.

Summary
Adds CDC ECM Ethernet over USB High Speed for SAMA5D36-Xplained
(and maybe other boards) (most of the code was there already,
but didn't work out of the box for the SAMA5D36-Xplained)
Only SAMA5D36-Xplained has been tested so far
Impact
None if you don't use the CDC ECM Ethernet driver
On SAMA5D36-Xplained, this adds high-speed Internet connectivity
over USB 2.0 High Speed. via the USB CDC ECM Gadget driver.
It may work on other boards too.
This also fixed full-speed (low-speed) mode for the board too.
Limitations
Hasn't been tested on anything other than SAMA5D36-Xplained board.
TODO
Ideally this would include a composite RNDIS device so it would
also work seamlessly on Windows. That is for a future PR
Ideally this would include software to help configuration via
mDNS/DNS-SD for plug and play compatibility with Linux and macOS.
That is for a future PR.
Detail
Only a few lines of C driver code needed to be changed, since the
capability was there already. The rest is config and documentation.
Changes the SAMA5D3-Xplained board bringup to match the SAMA5D3-EK
board bringup
A helper script to configure Linux routing and iptables NAT is also
provided, along with documentation on how to use it.
Testing
Manual, on a Ubuntu Linux 19.10 system and MacOS 10.14.6 Mojave
MacBook Pro.
How To Verify
Follow the new CDC ECM Ethernet over USB instructions in the board
README.txt file
Commits:
remove non-UTF-8 chars in comment and reformat
removed unneeded comment markers
instructions for using the defconfigs
removed EMAC from config
- to prove this example only needs the CDC ECM Ethernet over USB to work
added CDC-ECM Ethernet over USB info to README
added U-Boot image
added netusb helper script
- this can configure the Linux network interface and routes
so you can ping or access the NuttX system via TCP/IP.
renamed defconfig dirs to be ethernet-over-usb
- was usb-over-ethernet which is not right
added USB DMA to defconfigs
updated readme with autoboot and debugging info
bringing ethernet-over-usb examples into parity
added cdc ecm ethernet over usb with telnetd config
added defconfig
only use phy interrupt if netdevices is ethernet
- because now netdevice could be CDC ECM ethernet over usb
which has no PHY interrupt
add bringup to Makefile
add bringup
app init cleanup
init cdc ecm driver and rndis driver; some cleanup
fixed some typos and odd characters
usb over ethernet working over usb 2.0 hs
