Subject: Unable to Configure GRO in Testpmd
Hello Jiayu,
This's Wael from Mellanox DPDK team, I'm working on GRO feature and seems to be
not working on my machines, I do the following:
First I'm starting testpmd using the following command line:
"
/download/dpdk/x86_64-native-linuxapp-gcc/build/app/test-pmd/testpmd n 4 -w
82:00.0 -w 82:00.1 -- --burst=64 --mbcache=512 --portmask 0xf -i --txd=1024
--rxd=1024 --nb-cores=9 --rxq=2 --txq=2 --txqflags=0
"
Then:
Testpmd> set fwd csum
Testpmd> gro on 0
Testpmd> gro on 1
Testpmd> start
Then send the following TCP/IPV4 fragmented packet via scapy:
"
p=Ether(src=get_if_hwaddr('ens3f1'), dst=
'24:8A:07:8D:AE:B6')/IP(src='1.1.1.1',
dst='192.168.241.100')/TCP(sport=3512,dport=545)
p.add_payload(('F' * 500))
frags=fragment(p, fragsize=100)
for fragment in frags:send(fragment,iface="ens3f0")
"
"

|>>>

|>>>
"
With this configuration is the expected to receive the fragmented packets and
merge it as a single one?
Kindest Regards,
