esp_netif_set_dns_info() was available only for standard interfaces, not
for Point to point types (PPP, SLIP), but it should be normally
supported. Moreover DNS servers are global in lwip, so it doesn't really
depend on type of the interface.
Also added some minor fixes to the esp_netif_get_dns_info() to allow for
NULL parameters (as it's a public API) and hardcode the IPv4 type in
case of DHCP server capable interface.
Updated logs and added error checks to the original API, before we
launch the lwIP counterpart.

IP update notification for "point to point" interfaces is performed
via the same callback function as for any other interfaces (dhcp_cb,
although it's not DHCP related). In P2P interfaces we have to assure
that we always get a notification, so we can set the interface up.
This was omitted when getting the same IP address for the second
time, causing the PPPoS interface (in esp-modem applications) failing
to reconnect if disconnected.

It is required to define a mandatory dependency on lwip, so we
introduced esp_netif_stack component and made it require lwip, instead
of directly depending on lwip.
This enables building w-out lwip and support other TCP/IP stacks.
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
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)
* esp-netif to optionally depend on esp-eth (only for l2tap config)
* esp_eth.h now includes the original ethernet header and the
ethernet-netif glue layer
* Updated examples and test to explicitely use esp-eth dependency if
needed
This updates the minimal supported version of CMake to 3.16, which in turn enables us to use more CMake features and have a cleaner build system.
This is the version that provides most new features and also the one we use in our latest docker image for CI.
ESP_RETURN_ON_FALSE(a, err_code, ...) macro
Will print and return err_code
if (unlikely(!(a)))
so "a" needs to state what we expect to be TRUE
which in this case means:
mld6_leavegroup_netif(...) == ERR_OK
