Introducing config option `CONFIG_ESP_NETIF_SET_DNS_PER_DEFAULT_NETIF`
to overcome LWIP limitation of using global DNS server info.
This config option enables LWIP callbacks to collect per netif DNS
server info and then restores global DNS servers of whichever network
interface is selected as default.
LWIP submodule update v5.2: git log --oneline f1746813..3a3d1fb3
- dns: Allow storing dnsserver per netif (espressif/esp-lwip@3a3d1fb3)
- api_msg: Fix unused local variable if LWIP_NETCONN_SEM_PER_THREAD=1
(espressif/esp-lwip@aa4f6e78)
- lwip: fix gcc -fanalyzer warnings (espressif/esp-lwip@4297782b)
LWIP submodule update on v5.2: git log --oneline f7922143..f1746813
- feat(lwip): Added multiple dns ip support (espressif/esp-lwip@f1746813)
- api_msg: Fix crash to fail-safe error if cannot get semaphore (espressif/esp-lwip@a1bd9e44)
lower the dhcp discover and request retry backoff time
Closes WIFI-5646, WIFI-5647, WIFI-4774, WIFI-4823, and WIFI-5823

linux/lwip: Wrap some IO posix functions
* to workaourd the FreeRTOS EINTR issue (when building without lwip)
* to correctly choose the sub-system based on fd (when building with
lwip) -- passing control to either linux/system or to lwip
This commit also addapts tapio-if to provide DHCP client by default and
configurable settings for static IP
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.
Closes https://github.com/espressif/esp-idf/issues/9150
