Add a protocol argument to the VLAN packet tagging functions. In case of HW
tagging, we need that protocol available in the ndo_start_xmit functions,
so it is stored in a new field in the skb. The new field fits into a hole
(on 64 bit) and doesn't increase the sks's size.

Rename the hardware VLAN acceleration features to include "CTAG" to indicate
that they only support CTAGs. Follow up patches will introduce 802.1ad
server provider tagging (STAGs) and require the distinction for hardware not
supporting acclerating both.

This change is meant to address several race issues that become possible
because next_to_watch could possibly be set to a value that shows that the
descriptor is done when it is not. In order to correct that we instead make
next_to_watch a pointer that is set to NULL during cleanup, and set to the
eop_desc after the descriptor rings have been written.
To enforce proper ordering the next_to_watch pointer is not set until after
a wmb writing the values to the last descriptor in a transmit. In order to
guarantee that the descriptor is not read until after the eop_desc we use the
read_barrier_depends which is only really necessary on the alpha architecture.

Tighten up some of the code surrounding MAC addresses. Since the PF is
now giving all zeros instead of a random address, check for this case
and generate a random address. This ensures that we always know when we
have a random address and udev won't get upset about it.
Additionally, tighten up some of the log messages and clean up the
formatting.

Dan Carpenter noticed that ixgbevf initial default was different than
the rest. But the problem is broader than that, only one Intel driver (ixgb)
was doing it almost right.

Renamed dev_hw_addr_random to eth_hw_addr_random() to reflect that
this function only assign a random ethernet address (MAC). Removed
the second parameter (u8 *hwaddr), it's redundant since the also
given net_device already contains net_device->dev_addr.
Set it directly.
Adapt igbvf and ixgbevf to the changed function.
Small fix for ixgbevf_probe(): if ixgbevf_sw_init() fails
(which means the device got no dev_addr) handle the error and
jump to err_sw_init as already done by igbvf in similar case.

The existing ITR code is broken and confusing, with lots of similarly-named
variables that do different things. Additionally, after the driver carefully
determines the optimal interrupt rate for the adapter, it then
ignores it and always writes a fixed, suboptimal value.
This patch refactors that code to make variable names more descriptive of
what they actually do, and then actually writes the calculated result to
the hardware.
Preliminary testing shows that netperf TCP_STREAM tests goes from ~918Mbps
to ~940Mbps, and TCP_RR goes from ~2k transactions/sec up to > 8k.
