varies, this may cause a packet header error. Currently, there are two
methods in txonly mode to randomly change the packets.
1. Set txsplit random and txpkts (x[,y]*), the number of segments
   each packets will be a random value between 1 and total number of
   segments determined by txpkts settings.
   The step as follows:
     a) ./testpmd -w xxx -l xx -n 4 -- -i --disable-device-start
     b) port config 0 tx_offload multi_segs on

     d) set txsplit rand
     e) set txpkts 2048,2048,2048,2048

The nb_segs of the packets sent by testpmd will be 1~4. The real packet
length will be 2048, 4096, 6144 and 8192. But in fact the packet length
in ip header and udp header will be fixed by 8178 and 8158.

2. Set txonly-multi-flow. the ip address will be varied to generate
   multiple flow.
   The step as follows:
     a) ./testpmd -w xxx -l xx -n 4 -- -i --txonly-multi-flow
     b) set fwd txonly
     c) start
The ip address of each pkts will change randomly, but since the header
is fixed, the checksum may be a error value.

Therefore, this patch adds a function to update the packet length and
check sum in the pkts header when the txsplit mode is set to rand or
multi-flow is set.
