- RE: Handling fragmentation in NDIS IM Driver
- Posted by Bryan S. Burgin [MSFT] on August 11th, 2003
Gilad,
You won't be able to rely on any particular behavior. Even if you were
able to get a guarantee from TCPIP - and you can't - there may be other IM
drivers between it and your IM driver that might follow different rules.

Does anyone have a sample code for IP fragmentation
handling in an NDIS driver? I tried to look for any
sample, but found that all the samples ignore this issue.
Furthermore, I since IM is deserialized I can get multiple
fragments at the same time - what is the best way to
handle this? Is there a data structure available (such as
a hash table) that I can use for this?

As I said, copy fragmented packets to a local staging buffer. You can
"serialize" packet flow by using some packet queue mechanism and then
grabbing packets from the queue one by one and handle them. See
NdisInterlockedInsertTailList() etc.
