Add a fallback mechanism to ensure that there are still available
iobs for an free connection, Guarantees all connections will have
a minimum threshold iob to keep the connection not be hanged.

Patch fixes following build error when
CONFIG_NET_IPv6 && !CONFIG_NET_ICMPv6 && CONFIG_NET_ETHERNET:
nuttx/staging/libnet.a(neighbor_ethernet_out.o): In function `neighbor_ethernet_out':
nuttx/net/neighbor/neighbor_ethernet_out.c:188: undefined reference to `icmpv6_solicit'
IPv6 without ICMPv6 is not very useful, but at least this patch
allows neighbor_ethernet_out() to be used with a packet socket or
with multicast address (point-to-point IPv6 links) even in that case.

In the current net stack implementation, there is no mechanism
for notifying the loss of the wireless connection, if the network
is disconnected then application sends data packets through tcp,
the tcp_timer will keep retrying fetch the ack for awhile, the
connection status will not be able to be switched timely.

Fixes an issue where tcp sockets with activated keepalives stalled and
were not properly closed. Poll would not indicate a POLLHUP and therefore
locks down the application.
* tcp_conn_s.tcp_conn_s & tcp_conn_s.keepintvl changed to uint32_t
According RFC1122 keepidle MUST have a default of 2 hours.
N/A
Cause of curr maybe NULL, and following logic can handle this
