[dpdk-users] l2fwd example program error : Cannot init mbuf pool

["P D, Arun (Nokia - IN/Bangalore)" <arun.p_d@nokia.com>]

Hello,

I have been trying to run the example program of DPDK namely l2fwd. I have initialized the EAL environments. When I execute the l2fwd program I get error as below.

The error is its failing to initialie mbuf pool.

[root@localhost app]# ./l2fwd -c 2 -n 2
