Hi William,
That's what memif_refill_queue() does. When you call this function, libmemif
knows you are done with these buffers.

Hi William,
You do not need to copy the packets out of memif. Once you finish
processing all these packets, call memif_refill_queue() function to free these
buffers. Let's say if you receive 32 packets in memif_rx_burst function, after
processing, call memif_refill_queue with count=32 to
to check my setup.

Hi Macro,
Is there any sample code to show how to use SCTP (such as association, packet
transmission/reception, etc.)? And is there any performance report for SCTP?

Hi Daolin,
You can see the code below in gtpu4_encap node, if you set gtpu4_encap as next
node, the sw_if_index should be set correctly. In you case, it should be set to
the gtpu tunnel1.
sw_if_index0 = vnet_buffer(b0)->sw_if_index[VLIB_TX];
A workable solution is add a node as the next node
Hi Jakub,
I’m testing VPP memif and ICMP responder example app. I found there might be
some issues in extras/libmemif code when it runs in zero-copy mode.
1. In memif_connect1 function, only the first region is mmaped, while if
VPP memif runs in zero-copy mode, there will be multiple

Hi,
I have an issue when calculating the checksum of two IP headers with
ip4_header_checksum function. The content of these two IP headers are exactly
the same. The only difference between these 2 IP headers is that, one IP
header's address is 64 bits aligned, while the other one is not (My
