61e3f49f69 netif: Don't return error if pass NULL netif_input_fn to netif_add
The new NULL checking against netif_input_fn make ppp stop working
because in ppp_new() it calls netif_add with NULL netif_input_fn.

fd050b8a97 fix bug #53971 Lwip sends Router Solicitation on address changes
... and add a unit test for it.

Moved resetting netif->rs_count from all reports to link-up and netif-up only.
While at it, clean up the interface a bit so that netif->rs_count is touched
from nd6.c only.

ffaee59f3e loopif: only schedule poll when first packet is enqueued
This optimizes the netif_loop_output to only schedule a call to poll when
the first packet is enqueued. This ensures netif_poll is ran once per
burst of packets that are sent (which is typical in a TCP transfer)

The old behavior scheduled a call to poll for every packet that was
enqueued and this lead to exhaustion of the MEMP_TCPIP_MSG_API memory pool
and tcpip_mbox (if port is using static mbox size). The extra callbacks are
wasted work because netif_poll drains the entire queue when ran

This issue presented itself when large TCP transfer go across the loopback

070e449690 loopif: disable checksums
This disable checksum generation and checking for the loopback netif
when LWIP_CHECKSUM_CTRL_PER_NETIF is enabled

Checksums are not needed for the loopback adapter and this will increase
performance for loopback communication

6070a7ef6a netif: Add netif_do_ip_addr_changed function to reduce duplicated code
As the common code to call tcp/udp/raw_netif_ip_addr_changed is called
by multiple places, add netif_do_ip_addr_changed() to call them.

deab51c36d netif: Remove unnecessary NULL checking in netif_do_set_{ipaddr|netmask|gw}
The callers already ensure the ipaddr/netmask/gw won't be NULL, so remove
the duplicated NULL checking in these static functions.
While at it, also move the code saving old_address for netmask/gw as
it's only used when address is actually being changed.

2cb220d7fe netif: Move LWIP_ASSERT_CORE_LOCKED out of static functions
The netif_do_set_{ipaddr|netmask|gw} are static functions what won't be called
directly, thus move LWIP_ASSERT_CORE_LOCKED to netif_set_{ipaddr|netmask|gw}.
This avoid duplicated LWIP_ASSERT_CORE_LOCKED checking by netif_set_addr().

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
