In case of double buffering (two capture buffers), the CSI is
frequently starved because of a lack of buffer in the active pool.
You can find below an example of double buffering scenario:
FREE_BUF ACTIVE_BUF
start: 0 2
frame0_complete: 0 1 (no buffer to load in active)
resubmit_frame0: 1 1
frame1_complete: 1 0 (CSI stopped, active buf = 0)
resubmit_frame1: 2 0
0 -> 2 (CSI restarted)
This patch solves this issue by loading buffer to active at submit
time.
FREE_BUF ACTIVE_BUF
start: 0 2
frame0_complete: 0 1
resubmit_frame0: 1 1
0 -> 2 (Direct load to active)
frame1_complete: 0 1
resubmit_frame1: 1 1
0 -> 2

The network packet ref count was not properly increased when
the TCP was retried. This meant that the second time the packet
was sent, the device driver managed to release the TCP frame even
if we had not got ACK to it.
Somewhat long debug log follows:
The net_pkt 0x08072d5c is created, we write 1K data into it, initial ref
count is 1.
net_pkt_write: pkt 0x08072d5c data 0x08075d40 length 1024
net_tcp_queue_data: Queue 0x08072d5c len 1024
net_tcp_trace: pkt 0x08072d5c src 5001 dst 5001
net_tcp_trace: seq 0x15d2aa09 (366127625) ack 0x7f67d918
net_tcp_trace: flags uAPrsf
net_tcp_trace: win 1280 chk 0x0bea
net_tcp_queue_pkt: pkt 0x08072d5c new ref 2 (net_tcp_queue_pkt:850)
At this point, the ref is 2. Then the packet is sent as you see below.
net_pkt_ref_debug: TX [13] pkt 0x08072d5c ref 2 net_tcp_queue_pkt():850
net_tcp_send_data: Sending pkt 0x08072d5c (1084 bytes)
net_pkt_unref_debug: TX [13] pkt 0x08072d5c ref 1 (ethernet_send():597)
Ref is still correct, packet is still alive. We have not received ACK,
so the packet is resent.
tcp_retry_expired: ref pkt 0x08072d5c new ref 2 (tcp_retry_expired:233)
net_pkt_ref_debug: TX [10] pkt 0x08072d5c ref 2 tcp_retry_expired():233
net_pkt_unref_debug: TX [10] pkt 0x08072d5c ref 1 ... (net_if_tx():173)
net_pkt_unref_debug: TX [10] pkt 0x08072d5c ref 0 ... (net_if_tx():173)
Reference count is now wrong, it should have been 1. This is because we
did not increase the ref count when packet was placed first time into
sent list in tcp.c:tcp_retry_expired().
The fix is quite simple as you can see from this commit.

Test case added for IPv6 neighbors. This will add more than
CONFIG_NET_IPV6_MAX_NEIGHBORS neighbors. Network stack should
remove oldest neighbor which is in STALE state and it should
add new neighbor. So call to net_ipv6_nbr_add() should succeed.
Signed-off-by: Ravi kumar Veeramally <ravikumar.veeramally@linux.intel.com>
This patch fixes following issues.
* If IPv6 neighbor table is full, stack can not add any new
neighbors. So stale counter is introduced. Whenever neighbor
enters into STALE state, stale counter will be incremented
by one. When table is full and if stack wants to add new
neighbor, oldest neighbor in STALE state will be removed
and new neighbor will be added.
* When neighbor is in PROBE state and when it exceeds max
number of PROBEs, only neighbor with router is removed.
As per RFC 4861 Appendix C, entry can be discarded. Now
neighbor will be removed from the table.
* Reachability timer has an issue. e.g. if a first entry timer
is 10 seconds, after 3 seconds, a new entry added with
only 3 seconds. But current implementation does not check
whether remaining time of current left over timeout is more
than new entry timeout or not. In this example, when new entry
timeout is 3 seconds, left over timeout from first etnry is
still 7 seconds. If k_delayed_work_remaining_get() returns
some value then new entry time out was not considered.
Which is bad. It fixed now.
* nbr_free is used sometimes to remove the neighbor. Which does
not remove route if that particulat neighbor is route to some
other neighbor. net_ipv6_nbr_rm() should be used in such places.
* Trivial changes which does not affect functionality.

The treatment of the BT_DEV_READY flag was broken when used together
with BT_SETTINGS. The flag would get set even though the stack was
still in a partially initialized state. Even worse, for central role
the stack would potentially try to initiate passive scanning without
having an identity address.
Refactor the code that sets the BT_DEV_READY flag (among other
initialization) into a separate bt_finalize_init() helper function and
call it when the settings have been loaded. Also clarify the warning
message given to the user in case settings_load() needs to be called.
