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).
