* setsockopt(s, IPV6_ONLY, &one, sizeof(int)) will disable IPV6-only
mode. Incoming/outgoing IPV4 packets are dropped.
* Otherwise, sockets bound to IPV6_ANY_ADDR can receive unicast packets
for IPV4 or IPV6.
* sendto() a IPV6-mapped-IPV4 address on a UDP socket works correctly
(not supported for RAW or TCP sockets.)
* getaddrinfo() option AI_V4MAPPED is implemented.
As well as extending support to TCP & RAW, there is some potential improvement
to dropping incoming packets - the drop happens a bit late in the process and
there is no "ICMP port unreachable" response sent.
get IP address after connecting to the softap.
Now the default netif is station in station+softap mode. The UDP pcb of
DHCP server is binded to IP 0.0.0.0. When other device connects to softap, the
DHCP offer will be sent by softap.But because the destination IP of DHCP offer
is broadcast IP and the source IP of it is 0.0.0.0, it will be sent from default
netif, that is station interface. Other device can not receive the DHCP offer
sent from station interface. As a result, other device can not get IP address.
The resolution is that bind UDP pcb to the IP address of softap. So, the source
IP of DHCP offer is that of softap. DHCP offer can be sent from softap interface
by source IP route method.
Fix warnings where undefined vars are used.
Make Kconfig emit "FOO=" for unset bool options
To ensure make variables are always defined, even if empty.
When writing auto.conf, include symbols disabled by dependency to make sure all make variables are always defined.

Cherry-picked from https://github.com/espressif/esp-idf/pull/138
Optimize TCP close:
1. Not remove TCP pcb when IP address is changed since the lwip netconn still need the pcb
2. If the TCP connection is in TCP_FIN_WAIT_1 for too long time, remove it
If destination IP address of the packet is broadcast address, firstly compare
source IP address with the that of each network interface. If it matches,
packet is forwarded from the interface.
Triggered on make 3.81, happens sometimes on Linux and always(?) on macOS. May depend on the order the OS' filesystem
resolves wildcards in.
Includes a revert to the LWIP component to verify this is properly fixed.

fix(lwip): fix tcp connect fail when enable LOOPIF
when enable the LOOPIF, because of use the loopnetif, the TCP connect will fail. see TW12029

- reorder directories listed in COMPONENT_SRCDIRS so that
subdirectories precede parent directories
- don’t include PPP source directories if PPP support is not enabled
lwip: implement lwip critical session with mutex
Currently lwip critical session is based on interrupt, now replace it with mutex
See merge request !595
Change max number of open sockets
Change max number of open sockets from 16 to 32 because of MFI project need support 21 open sockets at least.
See merge request !532
Allow separate ethernet & wifi configuration
If only 1/2 of ethernet & WiFi are enabled in config, the other interface is no longer linked into the firmware.
* Fixes bug where enabling Ethernet but not WiFi would fail to compile.
* Also means that enabling WiFi but not Ethernet no longer links some unused ethernet interface functions.

lwip: modify dhcp timer granularity from 60s to 1s
Current DHCP granularity is 60 seconds, it's not accurate, it can cause DHCP release/rebind/renew timer
timeout at the same time, also it may renew/rebind/release at wrong time, thus cause problem.
1. modify the discover retry backoff time from (2,4,8,16,32,60,60)s to (500m,1,2,4,8,15,15)s.
2. add DHCP_DOES_ARP_CHECK to menuconfig for users to specify if do a ARP check on the offered address.
If enable, one more second will be taken in obtaining IP address.
3. update wifi libs
If the DNS request is dispatched and performed very quickly,
then it can complete before tcpip_callback() actually returns,
in which case we'll destroy the actual err_t error value passed
in the message. Use a local variable for the tcpip_callback
error code so that can't happen.
Resolves#269https://github.com/espressif/esp-idf/pull/269
add menuconfig option to enable SO_RCVBUF
This option is required by Arduino and enables netconn connection to be queried for amount of data available in the rx buffer.
See merge request !372
1. Update wifi lib which contains ampdu and other optimizations
2. Add throughput code debug code
3. Other misc modification about throughput optimization
1. The transmitting mode of the packets from LWIP to MAC is changed from synchronous to asynchronous.
2. The receive buf mode : support pointer mode and copy mode.
3. Add get phy status func used to config mac register.

1. fix tw8911 sleep in scan leads to auth frame malloc fail.
2. fix tw8913 pm state transfer wrong leads to wdt.
3. make some comments for modem sleep and wpa2 enterprise.
4. removd duplicated debug option ESP_THREAD_SAFE_DEBUG
lwip: fix socket memory leak issue
1. Add socket memory leak debug counter
2. Fix TCP PCB leak issue
Currently ESP32 support maximum 16 TCP PCBs and all TCP PCB are allocated from heap memory. In some scenario, we may
have memory leak issue, for example, the application already created 16 TCP PCB, then it close 5 of them, because the TCP
state machine, the LWIP core may not free all the 5 TCP PCB immediately, maybe some is in TIME_WAIT status, some is in
FIN_WAIT_1 etc. Then the application try to malloc 17th TCP PCB (the application think they just create 12 because they already
close 5), memp_malloc() will return true because the heap is not out of memory, but actually we got 17 TCP PCB. When the
scenario repeat again and again (in our Audio application, it repeat more than 10000 times), more and more TCP PCB will be
created in the system, each TCP PCB require 200B, then memory leak happen (In Audio application, I saw more than 26 TCP PCB
are created, and 10*200=2K memory are leaked).

LWIP will drop the oldest package at the arp packet cache queue and return "ERR_OK"
We change it that ARP level will drop the current packet and return "ERR_MEM" to tell user that you should send the packet again latter.
When the parameter pbuf for low_level_output is a list, malloc a new pbuf of
