Change the Sphinx default theme from "alabaster" to the ReadTheDocs
theme. See for example:
http://dpdk.readthedocs.org/en/latest/
This looks better for technical documentation and in particular
it has a 80 char wide verbatim block rendering.
Also add logos for the html and latex docs.

SR-IOV is supported using bnx2x poll mode driver running as VF driver and
native linux driver running as PF (in host/hypervisor). There is no issue
while running with the PF driver which is at the base version as that of
PMD. However, there is a compatibility issue between newer out-of-box PF
drivers with older VF driver. So the newer VFs would also need to send
BNX2X_VF_TLV_PHYS_PORT_ID (among other TLVs) to differentiate between
newer and older VFs.

If you stop and start the driver, the rx queue will have the previous
index values when programming the adapter. Therefore, we should always
reset the queue indices when the rx ring is setup. Note: We need to
clear (write) the status block's completion queue index since it is
possibly in a read cache.
Tidy some init code to make it clearer what the defaults are.

When refilling freelists for the first time and if it fails, the rxq
is freed and returns ENOMEM. There is a check while freeing hardware rxq
to pass freelist context id if the freelist exists or 0xffff otherwise.
The error path is only reached if freelist exists. So, fix is to remove
the useless check for freelist existence.

IEEE1588 forwarding mode uses same port to receive and transmit packets.
In this mode, the MAC address in the packets are not touched,
and therefore, packets could be sent with the same destination
MAC address as the MAC address of the port that is transmitting,
which causes the packet to be dropped in some NICs.
In order to avoid this scenario, MAC addresses are swapped
before packet is sent out.

The current implementation of VFIO will not with the new no-IOMMU mode
in 4.4 kernel. The original code assumed that IOMMU group zero would
never be used. Group numbers are assigned starting at zero, and up
until now the group numbers came from the hardware which is likely
to use group 0 for system devices that are not used with DPDK.
The fix is to allow 0 as a valid group and rearrange code
to split the return value from the group value.
