The MTU is assigned to the tap netdevice according to the argument, but
packet transmission and reception just write/read on an fd with the
default limit being the socket buffer size.
As a new rte_eth_dev_data is allocated during tap device init, ensure it
is set again dev->data->mtu.
Once the actual netdevice is created via tun_alloc(), make sure to apply
the desired MTU to the netdevice.

Since there is no "descriptor done" flag like on Intel drivers, the
approach is different on mlx5 driver.
- for Tx, we call txq_complete() to free descriptors processed by
the hw, then we check if the descriptor is between tail and head
- for Rx, we need to browse the cqes, managing compressed ones,
to get the number of used descriptors.

Introduce a new API to get the status of a descriptor.
For Rx, it is almost similar to rx_descriptor_done API, except it
differentiates "used" descriptors (which are hold by the driver and not
returned to the hardware).
For Tx, it is a new API.
The descriptor_done() API, and probably the rx_queue_count() API could
be replaced by this new API as soon as it is implemented on all PMDs.

e1000 igb driver does not implement a tx_rs_thresh to free mbufs, it
frees a slot in the ring as needed. However, it could be implemented at

The coremask option in DPDK is difficult to use and we should be
promoting the use of the corelist (-l) option. The patch
adjusts the docs to use -l EAL option instead of the -c option.
The patch only changes the docs and not the code as the -c option
will continue to exist unless it is removed in the future. The -c
option should be kept to maintain backward compatibility.

Every cells of a driver column are painted in yellow.
The trick is to generate some empty content as a big column
above and below the pointed cell.
The position: relative attribute is used for the highlight position
but it makes the border to disappear.
The overflow: hidden attribute is used to mask the generated content
outside of the table.
The class .wy-nav-content has a background which masks the highlighting.
Setting an opacity lower than 1, creates a new stack context and let
the column highlight to be shown.
The background of odd rows was grey and opaque. It is redefined with
a transparent alpha ratio in order to see highlighting on such rows.
