For datagram unix sockets, the `SO_SNDBUF` value imposes an upper limit on the size of outgoing datagrams.
Note: We don't support to change the buffer size yet, so only add support to getsockopt now.

When tun_txavail_work is running, switch to tun_close thread and priv->lock will be destroyed, then switch back to tun_txavail_work thread, an error will occur when nxmutex_unlock(&priv->lock)

When ESP32's BLE is enabled, select the option to pin the HCI TX
thread to a specific core. This is necessary to avoid problems
with the BLE task that runs pinned to the PRO CPU (core 0) while
running with SMP enabled.
By enabling the config `CONFIG_BLUETOOTH_TXCMD_PINNED_TO_CORE` and
setting the value of `CONFIG_BLUETOOTH_TXCMD_CORE`, it's possible
to pin the HCI TX thread to a specific core on a SMP-enabled setup.
This is necessary for devices that require that the function that
sends data (`bt_send`) to be called from a specific core.
1. Both IPv6 addresses and net masks should be stored in network byte
order
2. Fix last 2 bytes of mask applying (although it seldom triggers)

__dtoa is not used because currently NuttX uses other
function called __dtoa_engine() to do the same thing

For TOR: Any size and 4-byte aligned address is required
For NA4: Only size 4 and 4-byte aligned address is good
For NAPOT: Minimum size is 8 bytes, minimum base alignment is 8 bytes,
and size must be power-of-two aligned with base
This commit simplifies these checks and removes all the nonsense added
by a misunderstanding of how the MPFS / Polarfire SoC's PMP works.
These options are just wrong and a result of misunderstanding of the
Polarfire SoC spec. There are no feature limitations in the CPU PMP
implementation -> remove any configuration options added.
