Re: [vpp-dev] dpdk-20.02 compile error for Intel atom
looks like your compiler version is so old that it doesn’t know about
silvermont. You need newer one suggest gcc-8 at least.
Also if i read it right, you use kernel 3.10, suggest using something newer.
VPP uses syscalls which are not available in kernel 3.10

[vpp-dev] Observed Txpacket drops (dpdk tx failure)
Hi, I am seeing "Tx packet drops" on a VPP controlled DPDK device (VPP 18.07). Initially, traffic was working fine between the device and a SecGW connected via an IPsec tunnel. After a few hours, the device has become unreachable and ARP became unresolved. Cleared VPP counters and initiated the ping again, then observed that the ARP requests from SecGW were reaching the device but ARP response packets were dropping at DPDK. The below is the "show error" output when ping was initiated from SecGW to the device. CountNode Reason 7 pps-policer PPS Policer classify hits 7arp-input ARP req to host 13 kni-receive ARP req from Host 7 kni-receive ARP resp from Host 1ipsec-output-ip6IPSec pkts received 1ipsec-output-ip6IPSec policy bypass 1ip6-fragpacket smaller than MTU 1ip6-fragnumber of sent fragments 21 EthernetSwitch2/0/0-tx Tx packet drops (dpdk tx failure) The below is the "show hardware" output.
