When PTP is supported, the dma_mask should be fixed dynamically.

_dev_ is being dereferenced before it is null checked, hence there
is a potential null pointer dereference.
Fix this by moving the pointer dereference after _dev_ has been null
checked.

This patch adapts the tc command line interface to allow bandwidth limits
to be specified as a percentage of the interface's capacity.
Adding this functionality requires passing the specified device string to
each class/qdisc which changes the prototype for a couple of functions: the

The qdisc arg parsing has magic limit of 16 for class which is not required
by kernel. Also the limit of 16 for device name is really IFNAMSIZ.

Tuntap and similar devices can inject GSO packets. Accept type
VIRTIO_NET_HDR_GSO_UDP, even though not generating UFO natively.
Processes are expected to use feature negotiation such as TUNSETOFFLOAD
to detect supported offload types and refrain from injecting other
packet

This patch adds documentation for additional offload modes and
associated parameters in tc-mqprio.
