(1) Now the Ethernet is completely re-initialized when an error occurs by means of taking the interface down and back up but the PHY is _not_ renegotiated for that case because that is very time consuming and an error in the Ethernet is no reflection on the state of the PHY anyway.
(2) Explicitly sets the expected PHY address to zero (this could be moved into the config) rather than searching for it which takes ages, and it's zero anyway for this board (that's the broadcast address, and anything that cannot respond on that has multiple PHYs, so that would be a new board).
(3) Allows for the renegotiation of the PHY to be optional when a reset is needed. If a non-renegotiated reset doesn't result in good comms to the PHY then it'll automatically be escalated to a renegotiated one.
(4) Only performs a reset for errors that need it (the CRITICAL_ERROR define). The list of errors that need reset are somewhat arbitrarily chosen based on my prejudices and might need to be revisited, but certainly the jabber errors don't need reset, the partial packet is thrown away by the layer above anyway.
(5) Re-loads the multicast table on reset.
(6) Adds a bit more logging into the imxrt Ethernet module.
Pull request for mtd/progmem refactoring.
* mtd/progmem: change up_progmem_npages to up_progmem_neraseblocks
page is a unit for read/write operation.
eraseblock is a unit for erase operation.
up_progmem_npages is a little bit confusing because it returns number of
erase blocks in flash memory. This patch changes up_progmem_npages to
up_progmem_neraseblocks. There is no logical change.

* mtd/progmem: up_progmem_eraseblock
Change up_progmem_erasepage to up_progmem_eraseblock.
eraseblock is more readable name than erasepage.

* mtd/progmem: change up_progmem_eraseblock's return value.
up_progmem_eraseblock erase a block. so it's better to return the erase block
size than page size.

drivers/usbdev: Fix buffer overrun check in rndis.c
The rndis driver has been working since 13 Nov 2017.
However, I finally found that it depends on network and buffer
configurations. If a receiving TCP packet is devided into smaller
ones based on USB max packet size, this condition check works
correctly.

many locations: Change occurences of open() followed by file_detach() to file_open(). Change most non-controversion calls to open() to nx_open().
fs/inode/fs_fileopen.c: Flesh out file_open() with some interim, placeholder logic.
fs/inode/fs_fileopen.c: Add a framework for a file_open() implementation (no real logic in place yet).
fs/vfs/fs_open.c: Add nx_open() which is the same as open() except that it does not create a cancellation point nor does it modify the errno variable.
Squashed commit of the following:
Add procfs support to show stopped tasks. Add nxsig_action() to solve a chicken and egg problem: We needed to use sigaction to set default actions, but sigaction() would refuse to set actions if the default actions could not be caught or ignored.
sched/signal: Add configuration option to selectively enabled/disable default signal actions for SIGSTOP/SIGSTP/SIGCONT and SIGKILL/SIGINT. Fix some compilation issues.
sched/sched: Okay.. I figured out a way to handle state changes that may occur while they were stopped. If a task/thread was already blocked when SIGSTOP/SIGSTP was received, it will restart in the running state. I will appear that to the task/thread that the blocked condition was interrupt by a signal and returns the EINTR error.
sched/group and sched/sched: Finish framework for continue/resume logic.
sched/signal: Roughing out basic structure to support task suspend/resume

drivers/serial/Kconfig: It is no longer necessary to restrict Ctrl-C handling to the FLAT build
sched/signal: Add a new configuration option to select signal default actions, separate handling of signal default actions from both task startup logic and from the serial TTY Ctrl-C logic. Add a signal set in the group structure to keep track of what signals have been set to the default action. In dispatching signals in PROTECTED or KERNEL mode, use this signal set to determine if the default signal handler is attached and dispatch the signal in kernel mode for the default actions.

drivers/serial/uart_16550.c: Support 16550 auto hardware flow control
drivers/serial/uart_16550.c: Add configuration option CONFIG_16550_SUPRESS_INITIAL_CONFIG. This is identical to the standard configuration in arch/Kconfig CONFIG_SUPPRESS_UART_CONFIG, but with scope of only the 16550 driver.
drivers/serial/uart_16550.c: Add a configuration, analogous to the STM32 configuration option, to suppress the NuttX standard re-ordering for /dev/ttySN for special case of the 16550 UART.
config/serial: UART 16550: Add CONFIG_SERIAL_UART_ARCH_MMIO option so the a memory mapped device doesn't need to provide uart_getreg() and uart_putreg() implementations.
u16550_txempty() should check UART_LSR_TEMT to avoid some data left in the transmit FIFO
drivers/serial: Add Ctrl-C/Ctrl-X support. This is an initial working implementation that still requires that several details be resolved.
sched/task/task_start.c: Add default signal action to SIGKILL.
drivers/syslog: Channel configuration. Decouple SYSLOG_SERIAL_CONSOLE and ARCH_LOWPUTC. Since some hardware can output log to the special debug channel not serial.
drivers/syslog/vsyslog.c: Support pre-pending a prefix string to log output if enabled. This very useful to identify which cpu send out the log in AMP SoC.
drivers/syslog/vsyslog.c: Make timestamp output same as linux kernel. It's very useful if NuttX syslog retarget to Linux syslog.

No... I was misled. The shutdown function is usually called when the
driver is unlinked. But not in this case. In this case, it is simply
called when the last reference is closed. And no, you don't want to
detach the interrupt handler in that case. My bad.
This reverts commit b79e6b9c9a.
