ChangeLog

	  Ethernet and SLIP are enabled (2014-11-16).
	* net/, include/, various files:  Rename CONFIG_NET_RECEIVE_WINDOW to
	  CONFIG_NET_ETH_TCP_RECVWNDO and CONFIG_NET_SLIP_TCP_RECVWNDO.  Add
	  data structures and logic to handler different TCP receive windows
	  when both Ethernet and SLIP are enabled (2014-11-16).
	* configs/sama5d4-ek/bridge: Add a simple test for the dual EMACs on
	  the SAMA5D4 (2014-11-17).
	* arch/arm/src/sama5/sam_emacb.c:  Fix several typos that will prevent
	  EMAC1 from initializing properly (2014-11-17).
	* include/nuttx/net/ip.h and tcp.h, net/icmp/icmp_send.c and
	  igmp/igmp_send.c: Move IP header flags from tcp.h to ip.h and rename
	  IP_FLAGS vs TCPFLAGS.  The problem fixed here is that there IP flags
	  were not available when TCP was disabled.  The IP flags are used in
	  ICMP and IGMP (2014-11-17).
	* sched/clock/clock_abstime2ticks.c: Calling mq_timedreceived() with
	  immediate timeout was getting stuck and not timing out. Immediate
	  timeout is achieved by setting absolute timeout value to past time,
	  for example abstime={ .tv_sec=0, .tv_nsec=0 }. However absolute
	  time was converted to relative time using unsigned integer arithmetic
	  and resulted large ticks count by clock_abstime2ticks, instead of
	  expected negative ticks value.  Change corrects clock_abstime2ticks()
	  to return negative ticks, if absolute time is in the past.  From
	  Jussi Kivilinna (2014-11-19).
	* fs/vfs/fs_poll.c: poll() was not waking up from signals (for example
	  mq_notify() events).  From Jussi Kivilinna (2014-11-19).
	* arch/arm/src/stm32/stm32_otghs.c, Make.defs,
	  configs/stm32f429i-disco/src/stm32_usb.c and Makefile: STM32 F4 OTGHS
	  device controller driver from Brennan Ashton (2014-11-20).
	* configs/sama5d3-xplained/bridge: Add a simple test for the the EMAC
	  and GMAC on the SAMA5D3 working together (2014-11-20).
	* libnx/nxtk/nxtk_drawframe.c: Remove warnings when CONFIG_NXTK_BORDERWIDTH
	  is set to zero.  From Pierre-Noel Bouteville (2014-11-20).
	* fs/vfs/fs_poll.c: Add proper handling for sem_timedwait errnos.
	  From Jussi Kivilinna (2014-11-21).
	* net/udp/udp_conn.c and udp.h:  Extensions to UDP "connection" structure
	  for the case of multiple networks.  In this case, assigned port numbers
	  only have to be unique with response to the IP address.  So, for
	  example, you could have multiple port 80's, one on each network
	  (2014-11-21).
	* net/tcp/tcp_conn.c and tcp.h: Make tcp_listener static scope; it is
	  not used outside of tcp_conn.c (2014-11-22).
	* net/udp/tcp_conn.c and tcp.h:  Extensions to TCP connection structure
	  for the case of multiple networks.  See the description of the similar
	  change for UDP above (2014-11-22).
