Summary: [dpdk-25.11-rc0]
checksum_offload/do_not_insert_checksum_on_the_transmi
t_packet: core dumped occurred when send packets
Product: DPDK
Version: unspecified
Hardware: x86
OS: FreeBSD
Status: UNCONFIRMED
Severity: normal
Priority: Normal
Component: testpmd
Assignee: [email protected]
Reporter: [email protected]Target Milestone: ---
Step:
=====
1. bind ports to DPDK
kenv hw.nic_uio.bdfs="75:0:0,75:0:1,75:0:2,75:0:3" kldload ./x86_64-native-bsdapp-gcc/kmod/nic_uio.ko 2. exit testpmd
2. Launch testpmd
x86_64-native-bsdapp-gcc/app/dpdk-testpmd -l 0,28 -n 4 -a 0000:4b:00.0 -a
0000:4b:00.1 -a 0000:4b:00.2 -a 0000:4b:00.3 -- -i --portmask=0x1
--enable-rx-cksum --port-topology=loop
set verbose 1
set fwd csum
csum mac-swap off 0
start
3. send packets
sendp([Ether(dst="52:00:00:00:00:01", src="52:00:00:00:00:00")/IP(src="10.0.0.1",chksum=0x0)/UDP(chksum=0xf)/("X"*46),Ether(dst="52:00:00:00:00:01", src="52:00:00:00:00:00")/IP(src="10.0.0.1",chksum=0x0)/TCP(chksum=0xf)/("X"*46),Ether(dst="52:00:00:00:00:01", src="52:00:00:00:00:00")/IPv6(src="::1")/UDP(chksum=0xf)/("X"*46),Ether(dst="52:00:00:00:00:01", src="52:00:00:00:00:00")/IPv6(src="::1")/TCP(chksum=0xf)/("X"*46)],iface="ens801f0",count=4)
