            Bug ID: 1398
           Summary: [dpdk-24.03] ptpclient causes NIC I225/I226 port RX
                    missed
           Product: DPDK
           Version: unspecified
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: examples
          Assignee: dev at dpdk.org
          Reporter: tingtingx.liao at intel.com
  Target Milestone: ---

[Environment]
DPDK version: a86f381b8 version: 24.03-rc2
OS: Ubuntu 22.04.3 LTS/5.15.0-82-generic
Compiler: gcc (Ubuntu 11.4.0-1ubuntu1~22.04) 11.4.0
Hardware platform: Intel(R) Xeon(R) CPU E5-2699 v4 @ 2.20GHz
NIC hardware: Ethernet Controller I225-LM 15f2
NIC firmware:
driver: igc
version: 5.15.0-82-generic
firmware-version: 1003:8725

[Test Setup]
1. build dpdk-ptpclient
rm -rf x86_64-native-linuxapp-gcc
CC=gcc meson -Denable_kmods=True -Dlibdir=lib -Dc_args=-DRTE_LIBRTE_IEEE1588
--default-library=static x86_64-native-linuxapp-gcc
meson configure -Dexamples=ptpclient x86_64-native-linuxapp-gcc
ninja -C x86_64-native-linuxapp-gcc

2. bind port to vfio-pci and launch dpdk-ptpclient
./usertools/dpdk-devbind.py -b vfio-pci 81:00.0
./x86_64-native-linuxapp-gcc/examples/dpdk-ptpclient  -l 1-2 -n 4 -a
0000:81:00.0  --file-prefix=dpdk_2194090_20240312185937      -- -T 0 -p 0x1 &

3. kill it in a few seconds
killall dpdk-ptpclient

4. launch dpdk-testpmd
x86_64-native-linuxapp-gcc/app/dpdk-testpmd  -l 1-2 -n 4 -a 0000:81:00.0
--file-prefix=dpdk_1781719_20240309165130    -- -i --mbcache=200
--mbuf-size=1024 --portmask=0x1 --max-pkt-len=9000 --port-topology=loop
--tx-offloads=0x00008000
set verbose 1
set fwd mac
start

5. send packets with the peer of port
sendp([Ether(dst='00:a0:c9:00:00:00',
src='00:00:20:00:00:00')/IP()/Raw(load=b'X')],iface="ens162f0",count=1,inter=0)

6. check if port has received a packet

[Results]

    examples/ptpclient: add signal handler for cleanup



    This adds the signal handler for SIGINT, SIGTERM.
    Also, this will come out from infinite loop and do cleanup once it receives
    any of the registered signal.
