Add command line parameter:
--rxhdrs=eth[,ipv4]
Set the protocol_hdr of segments to scatter packets on receiving if
split feature is engaged. And the queues with BUFFER_SPLIT flag.
Add interactive mode command:
testpmd>set rxhdrs eth,ipv4,ipv4-udp
(protocol sequence should be valid)
The protocol split feature is off by default. To enable protocol split,
you need:
1. Start testpmd with multiple mempools. E.g. --mbuf-size=2048,2048
2. Configure Rx queue with rx_offload buffer split on.
3. Set the protocol type of buffer split. E.g. set rxhdrs eth,eth-ipv4
(default protocols of testpmd : eth|ipv4|ipv6|ipv4-tcp|ipv6-tcp|
ipv4-udp|ipv6-udp|ipv4-sctp|ipv6-sctp|grenat|inner-eth|
inner-ipv4|inner-ipv6|inner-ipv4-tcp|inner-ipv6-tcp|
inner-ipv4-udp|inner-ipv6-udp|inner-ipv4-sctp|inner-ipv6-sctp)
Above protocols can be configured in testpmd. But the configuration can
only be applied when it is supported by specific pmd.
