PR #14255 sets NETWORK_PRIORITY_BASE = 300.0, but PR #14012's
NetworkComponent uses setup_priority::AFTER_BLUETOOTH = 300.0f. When the
highest-priority interface (first in the priority list) tied with
NetworkComponent at 300, the runtime tie-break was determined by
registration order — and NetworkComponent registers AFTER ethernet (its
codegen runs at CoroPriority.NETWORK_SERVICES = 55, below COMMUNICATION
= 60 used by ethernet/wifi).
Result: ethernet's setup() ran before NetworkComponent::setup(),
esp_netif_init() had not yet been called, esp_netif_new() returned
NULL, and EthernetComponent::setup() dereferenced NULL in
esp_netif_attach() — LoadProhibited crash at boot.
Drop the base to 250.0 (matches the historical setup_priority::WIFI /
::ETHERNET default, so a single-entry priority list behaves identically
to a no-priority-block config) and shrink the step to 5.0 to keep all
interfaces in the same priority band, above BEFORE_CONNECTION (220.0)
and below AFTER_BLUETOOTH (300.0).
PR #14255 generates calls to Component::set_setup_priority(float) from
ethernet/wifi to_code(), but that method's body in core/component.cpp is
gated by #ifdef USE_SETUP_PRIORITY_OVERRIDE. Without the define the
declaration exists but no implementation is linked, producing:
undefined reference to `esphome::Component::set_setup_priority(float)`
The existing convention in cpp_helpers.register_component() is to add
the define whenever CONF_SETUP_PRIORITY appears in a component's YAML.
Mirror that here: when the user declares `network: priority:`, the
priority-driven setup_priority overrides will be emitted, so the define
must be on.
Resolves conflicts with PR #14012 (centralized netif init):
- wifi_component_esp_idf.cpp: dropped pr-14255's ESP_ERR_INVALID_STATE
tolerance hunk (made moot by #14012 removing the call entirely).
- ethernet/__init__.py: kept dev's refactored _to_code_esp32 structure;
added pr-14255's priority lookup and conditional CONFIG_ESP_WIFI_ENABLED
gating; preserved dev's top-level import shape.
- network/__init__.py: merged CONF_ID import (#14012) with CONF_PRIORITY
+ CONF_TIMEOUT imports (pr-14255).
Also fixed two latent bugs in pr-14255 where `"wifi" in net_priority`
compared a string against a list of dicts (always False). Replaced with
set comprehension over the normalized interface names.
