lwip/dhcpserver: Support for adding extra opts
...
This enables users appending an extra, user defined options in dhcp
server messages. Example of adding captive_portal option (160) to dhcp
offer message is provided:
* Add idf-lwip hook file (project makefile):
idf_component_get_property(lwip lwip COMPONENT_LIB)
target_compile_options(${lwip} PRIVATE "-I${PROJECT_DIR}/main")
target_compile_definitions(${lwip} PRIVATE "-DESP_IDF_LWIP_HOOK_FILENAME=\"add_captive_portal.h\"")
* Implement appending (add_captive_portal.h):
#pragma once
#define LWIP_HOOK_DHCPS_POST_APPEND_OPTS(netif, dhcp, state, pp_opts) \
if ((state)==DHCPOFFER) { *(pp_opts) = append_captive_portal_uri(*(pp_opts)); }
static inline uint8_t *append_captive_portal_uri(uint8_t *optptr)
{
const static uint8_t DHCP_OPTION_CAPTIVE_PORTAL=160;
const static char CAPTIVE_PORTAL_URI[]="my_uri";
int size = sizeof(CAPTIVE_PORTAL_URI) - 1;
*optptr++ = DHCP_OPTION_CAPTIVE_PORTAL;
*optptr++ = size;
for(int i = 0; i < size; ++i) {
*optptr++ = CAPTIVE_PORTAL_URI[i];
}
return optptr;
}

vfs/lwip: Fix docs on select() referencing wrong config
...
CONFIG_LWIP_USE_ONLY_LWIP_SELECT was deprecated long time ago and removed (~ in v4.x).
Used CONFIG_VFS_SUPPORT_SELECT instead (and reverted the logic as this
is ON by default and needs to be explicitly turned off for socket only
select)
