Add support for reception of jumbo frames
Jumbo frames are now supported through the addition of a "mtu" parameter of the port in the config file. Setting the mtu to a value higher than 1500 bytes will enable the reception of jumbo frames. In addition, the rte_eth_dev_set_mtu is now set for all pmds. Finally, setting mbuf_size does not set MEMPOOL_F_NO_SPREAD anymore. This option was only used for pure debugging. Big packets can be received using two ways - Using multiple "small" mbufs, i.e. around 2K. This is the default. - Using one big mbuf holding the whole packet. This can be enabled by setting a parameter mbuf_size in the receiving core configuration Change-Id: Idd60ad31f41c89f9522dff4d894af2696b7a2ea1 Signed-off-by: Xavier Simonart <xavier.simonart@intel.com>
