Subject: [dpdk-users] rte_flow() usage of htonl() for ipv4 addr masks?
Date: Sun, 9 Aug 2020 21:03:12 -0500
Message-ID: <CAHJJQSVpmT=Nhe5yoswQFTkRMZC1cVpcpuH99bY=t04vWKqEow@mail.gmail.com> (raw)

Hi,

In the flow_filtering sample application, the IP's mask was set without
using htonl().
https://github.com/DPDK/dpdk/blob/master/examples/flow_filtering/flow_blocks.c#L85

Another DPDK page <https://doc.dpdk.org/guides/howto/rte_flow.html> shows
how a testpmd command is translated to C code.
On this page though, Example 4.2 (Range IPv4 drop) has used htonl() to set
the mask.

Any clarification on how to load the mask would be helpful.

Thanks,
Arvind
