Has anyone else encountered NFS hangs while doing writes from an
AIX RT to a Sun disk partition? Near as I can tell, the r_inetlen
parameter specified in the /etc/net file can not be 1518 when you
are doing NFS mounts to Suns...although it works fine to Ultrix 2.X
VAX machines. I can't find any documentation on this "maximum packet
length - r_inetlen" paramter and am wondering if 1518 is "standard"
in the rest of the TCP/IP world or what...why does IBM ship 1518 as
the default inetlen if a popular platform like Suns can't handle packets
over 1500?? (At 1518, the Sun console would print "ie0: huge packet")

From Sun:
/usr/include/net/if_ieee802.h:#define	MAX_8023_DLEN		1500
