Subject: [dpdk-dev] [dpdk-users] Issue in draining packets when head is null
Date: Mon, 13 Jan 2020 13:04:33 +0530	[thread overview]
Message-ID: <CAMfGv3=AtM+rqrhVRRH3wfiJskvrcp4ikB+B9S+=UrAq8A2n8A@mail.gmail.com> (raw)

Hi all,
This is regarding an issue in the draining packet using rte_reorder_drain.
Suppose we have a window size of 16 and we get packets with sequence no
like 0,1,2,4,5,6. On performing drain operation, I retrieve packets like
0,1,2.
Since now order_buf->entries[order_buf->head] i.e. order_buf->entries[3] is
null i won't be able to any more like 4,5,6. I would be able to do it only
when I get at a packet with a sequence number above window size. This may
be highly undesirable if we have large window sizes say 1024, 2048, etc. we
wouldn't be able to drain any more packets until a packet above window size
is received. Also since the struct rte_rorder_buffer are defined in the
source .c file, we are not able to move head of buffer from applications. *Is
there any specific reasons why it is implemented like this in the library.
Are there any ways to overcome this.*
