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: git log --oneline aa4f6e78..3a3d1fb3
- dns: Allow storing dnsserver per netif (espressif/esp-lwip@3a3d1fb3)
UDP application sends packet using esp_netif, underlying transport such
as Wi-Fi may drop the packet due to higher load. New error code
represent transient, non-fatal packet drop error. udp application may
use such errtype, for example to rate limit.
Fixed memory leak in emac_esp_new_dma function.
Polished ESP EMAC cache management.
Added emac_periph definitions based on SoC features and improved(generalized) ESP EMAC GPIO
initialization.
Added ESP EMAC GPIO reservation.
Added check for frame error condition indicated by EMAC DMA and created a target test.
DHCP Option 114 provides a modern method of indicating a captive
portal redirect to DHCP client. This introduces Option 114 to
the DHCPS component as well as provides examples for usage.
* All components which won't build (yet) on Linux are excluded.
This enables switching to Linux in an application without
explicitly setting COMPONENTS to main in the main
CMakeLists.txt.
* ESP Timer provides headers for Linux now
* automatically disabling LWIP in Kconfig if it is not available
doc(linux): brought section
"Component Linux/Mock Support Overview" up to date
This commit removes the lock from the list manipulation code in esp_netif_objects.c,
because we already have another lock/task context for lwip.
So the list manipulation is unsafe and safety must be assured by the stack layer
(in esp_netif_lwip).
Problems with current locking:
* implementation of locking was wrong -- lazy init style of creating the mutex is not
thread safe (and destroying it if we have no interface makes the problem exhibit very frequently)
* locking only the list won't solve issues when assessing interfaces atomically
* maintaining multiple locks is problematic, as we often switch between
lwip context and user context in internal implementation of esp_netif_lwip

PPP netif: Used allocated packet buffers of exact size
for input to TCP/IP stack to consume less memory in download mode
(compared to the previously used fixed sized packet buffers)
If LCP keepalive mechanism is enabled in menuconfig, it's statically
configured on creation of an interface and cannot be changed runtime. In
some cases it's useful to relax LCP criteria during runtime operation,
for example before initiating OTA. This config option allows for
disabling already enabled LCP echo (this setting becomes effective after
reconnecting, i.e. initializing a new session)
