lwip/netif struct has two places to store user's data
* netif->state (1 void*) but that might be occupied in special cases
* netif->client_dtat (n void*s) but that must be enabled in opts.h
This commit stores esp_netif_t* primarily in state, but if any special
netif is enabled in menuconfig (bridgeif, pppos), it uses netif->client_data.
This commit also fixes incorrect esp_netif that is attached to
IP_EVENT_GOT_IP6 event posted by pppos interfaces in:
c585618b97/components/esp_netif/lwip/esp_netif_lwip_ppp.c (L114)
Closes https://github.com/espressif/esp-idf/issues/9345
This function removes the following legacy atomic CAS functions:
From compare_set.h (file removed):
- compare_and_set_native()
- compare_and_set_extram()
From portmacro.h
- uxPortCompareSet()
- uxPortCompareSetExtram()
Users should call esp_cpu_compare_and_set() instead as this function hides the details
of atomic CAS on internal and external RAM addresses.
Due to the removal of compare_set.h, some missing header includes are also fixed in this commit.
Fix dependency tree so that lwip doesn't depend on any specific network
interface component.
Network interface drivers shall depend on esp_netif.
esp_netif shall depend on lwip (but not on any specific interface
driver) -- it optionally depends on vfs and esp_eth (need ethernet
header for L2/bridge mode)
If on-demand timers (IGMP+MLD6) were enabled, idf updated user config
MEMP_NUM_SYS_TIMEOUT. The implementation of these timers are in lwip
project so the internal system timeout shall be updated accordingly,
enabling port layers to modify MEMP_NUM_SYS_TIMEOUT.

This commit updates and refactors the AFL host test mock as follows:
- Isolates the mock so that it only relies on lwip component and linux stdlib headers
- Grouped all mock functions in 'esp32_mock.h/c'
- Updates the lwip esp32 port files to include 'esp32_mock.h' when building for linux
- Use host stdlib headers instead of xtensa stdlib headers

This commit updates the visibility of various header files and cleans up
some unnecessary inclusions. Also, this commit removes certain header
include paths which were maintained for backward compatibility.
`lwip_select` uses `sys_arch_sem_wait` function making the assumption that it
is POSIX compliant. This commit makes that function wait for at least
timeout (milliseconds), as required by POSIX specification.

This commit removes the usage of all legacy FreeRTOS data types that
are exposed via configENABLE_BACKWARD_COMPATIBILITY. Legacy types can
still be used by enabling CONFIG_FREERTOS_ENABLE_BACKWARD_COMPATIBILITY.
LWIP has two definess for setting max number of sntp servers:
- Total number of handled servers
- max number of sntp's picked via DHCP
by default both values are equal to 1, but could be set separately

This commit brings two esp-lwip fixes to IDF:
1) Add configuration to disable DHCP client identification
2195f7416f
This config could be used to disable option 61 in DHCP packets, so that
clients will be identified by their chaddr only.
(This is the lwip upstream original behaviour)
2) Fix server_idx increasing to DNS_MAX_SERVERS and trigger the LWIP_ASSERT
5a567d52f7
When lwip doesn't have DNS server and resolve a domain address, the server_idx
will increase to DNS_MAX_SERVERS, which will trigger the LWIP_ASSERT and make device crash.
Closes https://github.com/espressif/esp-idf/issues/6878
If silent assert configuration is enabled, LWIP asserts are now 'silent' also.
Also updates KConfig to note that LWIP asserts are also disabled when asserts
are disabled globally (this was already the behaviour, but the config item
suggested otherwise.)
Progress towards https://github.com/espressif/esp-idf/issues/5873
This caused some unsigned int prints out to be printed as singed integer which made the logs unreadable, for example sequence numbers in TCP packet headers
LWIP_HOOK_FILENAME is used in IDF to define standard and default hooks for IDF port in LWIP.
Added ESP_IDF_LWIP_HOOK_FILENAME to customize additional hooks in lwip
Closes https://github.com/espressif/esp-idf/issues/6261
Added lwIP hooks which could be optionally overwritten in the
application code. These three options are provided in Kconfig:
* NONE: No hook support
* DEFAULT: Default implementation is provided. If IDF doesn't
have a specific hook implementation, an empty stub is provided, which
could be overwritten by strong implementation in application code.
* CUSTOM: Hooks are declared only to be implemented in application code.
