David Cermak c93298c31d lwip: Add config for DHCP client id; Fix DNS server idx assert issue ... This commit brings two esp-lwip fixes to IDF: 1) Add configuration to disable DHCP client identification 2195f7416f This config could be used to disable option 61 in DHCP packets, so that clients will be identified by their chaddr only. (This is the lwip upstream original behaviour) 2) Fix server_idx increasing to DNS_MAX_SERVERS and trigger the LWIP_ASSERT 5a567d52f7 When lwip doesn't have DNS server and resolve a domain address, the server_idx will increase to DNS_MAX_SERVERS, which will trigger the LWIP_ASSERT and make device crash. Closes https://github.com/espressif/esp-idf/issues/6878		2021-06-23 12:52:18 +08:00
