	syssrc/sys/net: if.c if.h
	syssrc/sys/netinet: ip_fil.c ip_flow.c ip_input.c ip_output.c
	    tcp_input.c udp_usrreq.c

Log Message:
Split the pre-computed ifnet checksum flags into Tx and Rx directions.
Add capabilities bits that indicate an interface can only perform
in-bound TCPv4 or UDPv4 checksums.  There is at least one Gig-E chip
for which this is true (Level One LXT-1001), and this is also the
case for the Intel i82559 10/100 Ethernet chips.
