8c6884b2db tcp_close_shutdown: always deallocate the pcb if there is unread data on close (see bug #52403)
We preserved the TIME_WAIT handling before, but it seems this is not correct: we want to issue
a RST later again if someone wants to talk to this port. With TIME_WAIT, this might not always
the case.

40a563cdd3 dns: Use dns_backupserver_available() instead of open-coded
Slightly better readability by calling dns_backupserver_available()
instead of open-coded. Also move dns_backupserver_available() function
up to avoid forward declaration.

637bce91b4 netif: ensure link and admin states are up in issue reports (bug #52353)
This fixes a bug where some callers of netif_issue_reports were not
checking that both link and admin states were up, leading to extraneous
reports when calling one of the following

 1) netif_set_ipaddr
 2) netif_ip6_addr_set_parts
 3) netif_ip6_addr_set_state

The bug has been fixed by placing link and admin state checks in
netif_issue_reports and not requiring the callers to perform this
checking

472f7985b5 Introduce LWIP_PACKED_CAST to fix error issue with ARMCC
ARMCC when using __packed structures will not implicitly convert a
pointer to a member of a packed structure to something which does not
have __packed. This results in a compiler error and was found with calls
to icmp6_param_problem

While there is a #pragma pack mode in ARMCC that disables this error, it
does require existing ports to switch over their packing mode and
perform integration

de531131c5 Fix compiler warnings seen with clang 8.1.0 on MacOS
This fixes the following warnings:

test_tcp.c:266:5: error: code will never be executed [-Werror,-Wunreachable-code]
    pbuf_free(p);
    ^~~~~~~~~
 - The check API 'fail' aborts the test, thus pbuf_free(p) will never be executed

pbuf.c:783:111: error: format specifies type 'unsigned short' but the argument has type 'u8_t' (aka 'unsigned char') [-Werror,-Wformat]
      LWIP_DEBUGF( PBUF_DEBUG | LWIP_DBG_TRACE, ("pbuf_free: %p has ref %"U16_F", ending here.\n", (void *)p, ref));
      ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~
 - LWIP_PBUF_REF_T is u8_t by default and doesn't match U16_F, so cast to u16_t. The cast and formatter will need to be changed
   if ref is larger than 16 bits

ethernet.c:105:16: error: format specifies type 'unsigned char' but the argument has type 'unsigned int' [-Werror,-Wformat]
               (unsigned)ethhdr->dest.addr[0], (unsigned)ethhdr->dest.addr[1], (unsigned)ethhdr->dest.addr[2],
~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 - addr[] is type u8_t, formatter is X8_F which should be 8 bits. 'unsigned' is an int, so cast to unsighed char instead

dbd726959c [PATCH] Replace the OOSEQ max bytes and pbufs constants with functions.
Some systems need to take into account an RX buffer pool size when
advising an appropriate number of RX pbufs to queue on the ooseq
list. For some systems there is a practical hard limit beyond which
the rx pool becomes exhausted blocking reception of further buffers
until some are freed.

It also helps to be able to consider the available dynamic memory when
advising an appropriate maximum number of bytes to buffer on the ooseq
list.

These decisions can also benefit from knowing the number already
allocated on a particular pcb, so the ooseq tcp segement is passed to
these functions. For example, if the system only wants to allow the
total number of rx pbufs queued on all the ooseq lists to grow by one
and a pcb already has two then it can return three for this call, but
might return one for another call - supporting a greedy allocation
strategy.
