yes that's true.
since i am using the adaptive LZW
compression scheme it requires construction of string
table for compression/decompression. So an ip packet
of size 1500 bytes requires a table of size (4KB +
4KB + 2KB =12KB).
further still i copy the ip packet
data in another data buffer (about 1.4KB) and
then compress it.
So all this adds up to about 14KB.
Right now i can't do with less than 14KB.
as i said before the compression/decompression works
fine. but soon the kernel would panic with one
of the vm_fault: error message.
what would be the best possible way to
allocate/deallocate 14KB memory per packet without
causing vm_faults ??
is there anything i am missing ??
thanks
