The DHCP spec allows the server to specify the MTU. This can be useful for netbooting with UDP-based NFS-root on a network using jumbo frames. This patch allows the kernel IP autoconfiguration to handle this option correctly. It would be possible to use initramfs and add a script to set the MTU, but that seems like a complicated solution if no initramfs is otherwise necessary, and would bloat the kernel image more than this code would. This patch was originally submitted to LKML in 2003 by Hans-Peter Jansen. Signed-off-by: Chris Friesen <cfriesen@nortel.com> Signed-off-by: David S. Miller <davem@davemloft.net>
