Actually, this is not what I want. I would like to just use an IRQ
resource with the correct IRQ number. What I want is to hide the IRQ
domain knowledge elsewhere. For instance, in the wrs_device module
that register all our devices. But, since I have to update the kernel
with the least number of changes I will leave this for the future.

Set-up VLAN related registers during driver load instead of during opening
(bringing up) interfaces.
From now VLANs can be configured after loading the driver, but before bringing
up of interfaces. By this no switching is done without VLANs beeing configured.

When the switch is loaded, some PTP outgoing frames get discarded, so we
never get back the timestamp interrupt.  By round-robin'ing the slots,
we get back to the "busy" one, which holds an skb structure that must be
released.

Without this freeing, the skb remains in the output queue of the
socket, and after a while we get EAGAIN in send() because the buffer
is full (400 frames, more or less). And the ptp port is stuck until we
reopen the socket.

This diagnosis exposed the fact that it's not an overflow of pending
descriptors, so I change the message from

  descriptor overflow: tx timestamp pending

to

  discarding tx frame that got no timestamp

Finally, this is pr_warn, not pr_err as we now know it's expected.

In kernel this function returns 1/true on success!

- Remove only for write in #72557df
- NetworkManger (Unbuntu LTS 12.04) insists on accessing to the phy
when it is used from LM32 and flood the dmesg so we remove the warning.

NetworkManager tries to access the phy, so this WARN_ON is
pretty common if the daemon is running. Now we know who is
misbehaving, and the driver can keep silent (disclaimer: this
opinionated message is by Alessandro :)

The calibration procedures are defined but never called. They
were used in wrs-V2 hardware, but callers disappeared in January 2012.
Better remove them than let them rust forever.

This fixes an oops when programs access ethtool methods, especially
wrn_get_drvinfo. It can be reproduced by a simple run of "irqbalance",
which I never did in my development machine.
