Hi While testing my network driver with pktgen I could see an skb greater than 16K without fragments in xmit function. This lead to a fix in my driver that assumes when an SKB whose length is greater than 16K will come with fragments. Apart from pktgen what are the chances or possibilities of getting an SKB greater than 16K without fragments? . When I tried with tools like iperf/iper3/netperf, didn’t see a single incidence where the SKB length is greater than 16K and without frags. Even socket layer I see function alloc_skb_with_frags, does this mean all the larger packets come with frags.
Please pardon if it is not a correct mailing list to ask above question. Thanks Pradeep.
