I plan to use a simple IOB chain w/o IOB queue for tcp recv buffers.
for large configurations, uint16_t is not large enough to represent
the entire socket buffer.
* Move the code to advance rcvseq for user data from tcp_input
to receive handlers.
Motivation: allow partial ack.
* If we drop a segment, ignore FIN as well. Note than tcp FIN bit is
logically after the user data in the same segment.
Summary:
- I noticed that NFS over TCP does not work correctly when
it tried to reconnect to the NFS server.
- This commit fixes this issue
Impact:
- gs2200m only
Testing:
- Tested with spresense:wifi_smp
- NOTE: need to update gs2200m_main.c

Summary:
- I noticed that an NFS connection is automatically dropped.
- Actually, this happens in TCP mode if no traffic happens
for 600 seconds.
- I confirmed that the NFS client on Ubuntu automatically
reconnects to the NFS server when an RPC call failed.
- This commit adds the same behavior to fix the issue.
Impact:
- NFS client in TCP mode
Testing:
- Tested with spresense:rndis_smp

Decouple the IRAM heap from the text allocator since that heap can
still be used as a generic pool of memory.
Implement the up_extraheaps_init function to initialize all of the
additional heaps.

For now it's used to enable APIs to initialize the different heaps
during the start sequence but can be extended for other purposes that
manage those heaps.

Write protection must be disabled before performing changes to the WDT
registers. Furthermore, the routine was resetting the wrong field from
the RTC WDT register.
The RTC_CNTL_WDT_FLASHBOOT_MOD_EN field relates to Flash Boot Protection
and it is enabled by the 1st stage bootloader. The 2nd stage bootloader
takes care of disabling it.
Then the 2nd stage bootloader enables the RTC WDT for checking the
startup sequence of the application image.

Summary:
- I noticed that Telnet session is sometimes not closed
when tested with nxplayer + command stress test
- The symptom relates to the change of IOB throttling in TCP
but we are still finding the root cause.
- This commit is just a workaround to avoid the issue by
disabling telnet character mode.
Impact:
- spresense:rndis, spresense:rndis_smp only
Testing:
- Tested with nxplayer (HTTP audio streaming) + command stress test

With this we also don't need two separate linker scripts (one for IRAM
and another one for FLASH). Only one linker script (now called
esp32.ld) is now present.

be used for data storage and code execution.
