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
