660255695f On second thought, better restrict the mtu to between 72-65535...strange 
things happen otherwise.

75ee03cb27 Enforce the mtu to between the range 1-65535 before calling the driver 
ioctl routine.

866dba7305 Changed B_AGE policy to work correctly in a world with relatively large

16f62314cd Incorporated post 1.1.5 work from John Dyson. This includes performance 
improvements via the new routines pmap_qenter/pmap_qremove and pmap_kenter/
pmap_kremove. These routine allow fast mapping of pages for those
architectures that have "normal" MMUs. Also included is a fix to the
pageout daemon to properly check a queue end condition.

0d2afceedd Process scheduling changes - adapted from FreeBSD 1.1.5. Basically, 
charge scheduling CPU of child process to the parent and have child
inherit scheduling CPU from parent on fork. Makes a **big** difference
in the feel of the system to interactive users.

d23d07ef95 Merged in post-1.1.5 work done by myself and John Dyson. This includes: 
me:
1) TLB flush optimization that effectively eliminates half of all of the
   TLB flushes. This works by only flushing the TLB when a page is "present"
   in memory (i.e. the valid bit is set in the page table entry). See section
   5.3.5 of the Intel 386 Programmer's Reference Manual.
2) The handling of "CMAP" has been improved to catch attempts at multiple
   simultaneous use.

John:
1) Added pmap_qenter/pmap_qremove functions for fast mapping of pages into
   the kernel. This is for future optimizations and support for the upcoming
   merged VM/buffer cache.

b53902964f fixed bug where large amounts of unidirectional UDP traffic would fill 
the interface output queue and further udp packets would be fragmented
and only partially sent - keeping the output queue full and jamming the
network, but not actually getting any real work done (because you can't
send just 'part' of a udp packet - if you fragment it, you must send
the whole thing). The fix involves adding a check to make sure that the
output queue has sufficient space for all of the fragments.
