            Bug ID: 754
           Summary: quick question about including netinet/ip.h in
                    rte_ethdev.h
           Product: DPDK
           Version: 19.11
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: ethdev
          Assignee: dev@dpdk.org
          Reporter: jy7805.heo@samsung.com
  Target Milestone: ---

Hello all, 

I'm making some application using DPDK. Once I want to include <linux/ip.h> and
<rte_ethdev.h> together, below redefinition error is being show. 


/usr/include/linux/ip.h:86:8: error: redefinition of ‘struct iphdr’
 struct iphdr {
        ^~~~~
In file included from /usr/local/include/rte_ip.h:21:0,
                 from /usr/local/include/rte_flow.h:24,
                 from /usr/local/include/rte_eth_ctrl.h:11,
                 from /usr/local/include/rte_ethdev.h:978,
                 from
/home/jy7805.heo/git/srsLTE/lib/include/srslte/dpdk/dpdk_utils.h:18,
                 from
/home/jy7805.heo/git/srsLTE/lib/include/srslte/dpdk/dpdk_threads.h:9,
                 from
/home/jy7805.heo/git/srsLTE/lib/include/srslte/ph_thread/ph_tx.h:4,
                 from /home/jy7805.heo/git/srsLTE/lib/src/ph_thread/ph_tx.cc:1:

I found that rte_ip.h is including netinet/ip.h which is making collision with
linux/ip.h

Does anyone who ever seen this kind of error before ? Should I change
linux/ip.h to netinet/ip.h ? 

Thank you. 

Thank you.

What distribution? 
In the general the simple solution is not include linux/ip.h
