gso_type is being used in binary AND operations together with SKB_GSO_UDP.
The issue is that variable gso_type is of type unsigned short and
SKB_GSO_UDP expands to more than 16 bits:
SKB_GSO_UDP = 1 << 16
this makes any binary AND operation between gso_type and SKB_GSO_UDP to
be always zero, henc

Now for the abandoned chunks in unsent outq, it would just free the chunks.

Now outstanding_bytes is only increased when appending chunks into one

Now when doing asoc reset, it cleans up sacked and abandoned queues

It's safe for the sender of response, as these 3 queues are empty at

When doing asoc reset, if the sender of the response has already sent some
chunk and increased asoc->next_tsn before the duplicate request comes, the
response will use the old result with an incorrect sender next_tsn.

the send
As it says in rfc6525#section5.1.4, before sending the request,

outstanding TSNs abandoned.
Prior to this patch, it tried to consider all outstanding TSNs abandoned

Now the out stream reset in sctp stream reconf could be done even if
the stream outq is not empty. It means that users can not be sure

To make this more synchronous, it shouldn't allow to do out stream
reset until these chunks in unsent outq all are sent o
This patchset is to make stream reset and asoc reset work more correctly
for stream reconfig.
Thank to Marcelo making them very clear.
Xin Long (5):
sctp: use sizeof(__u16) for each stream number length instead of magic
number
sctp: only allow the out stream reset when the stream outq is
Now in stream reconf part there are still some places using magic
number 2 for each stream number length. To make it more readable,
this patch is to replace them with sizeof(__u16).
