Consider a bi-directional TCP connection:
1. we use all IOBs for tx queue
2. we advertize zero recv window because we have no free IOBs
3. if the peer tcp does the same thing,
both sides advertize zero window and can not drain the tx queue.
For a similar stall to happen, the peer doesn't need to be
a naive tcp implementation like nuttx. A naive application blocking
on send() without draining its read buffer is enough.
(Probably such an application should be fixed to drain rx even
when tx is full. However, it's another story.)
This commit avoids the situation by prevent tx from grabbing
the all IOBs in the first place. (assuming CONFIG_IOB_THROTTLE > 0)

Since we do not have the Nagle's algorithm,
the TCP_NODELAY socket option is enabled by default.

1. Added check for repeated connection wifi operations.
2. Invoke the carrier on/off operation in the wrong place.
3. The RTC initialization time is incorrect.
4. Reserve 32K I-Cache space in the linker script.
5. Increase the size of the wifi firmware receiving buffer.

Since a SOL option IP_TTL exist, we should rename this IP_TTL
in netconfig.h to avoid confusion.

quote from https://man7.org/linux/man-pages/man2/sendfile.2.html:
If offset is not NULL, then it points to a variable holding the
file offset from which sendfile() will start reading data from
in_fd. When sendfile() returns, this variable will be set to the
offset of the byte following the last byte that was read. If
offset is not NULL, then sendfile() does not modify the file
offset of in_fd; otherwise the file offset is adjusted to reflect
the number of bytes read from in_fd.
If offset is NULL, then data will be read from in_fd starting at
the file offset, and the file offset will be updated by the call.
The change also align with the implementation at:

Fix a problem where the log function would loop infinitely by
calculation error when a specific value was passed. For example,
in the following case, the log function loops infinitely and
never returns. So, this commit fixes to return the right value.
double a = 7883961.5;
double b = log(a);
