This patch corrects a message bug in the via-velocity driver which
bothered me for some time.
The messages printed during device init look like the following:
[ 8.486422] eth%d: set value of parameter Wake On Lan options to 0
^^!
[ 8.487340] eth0: VIA Networking Velocity Family Gigabit Ethernet Adapter
Note the unresolved format string.
dev->name is unavailable before register_netdev, so use
dev_driver_string(&pdev->dev), which is also consistent with other
drivers.
"char *devname" parameters had to be converted to "const char *devname" to
be consistent with dev_driver_string return value.

Updates of the RBRDU have two different meanings depending on their
context:
1. the receiving process has not started - the value which is written
into the RBRDU register is supposed to be the free rx descriptors
count (rounded to a multiple of 4)
2. the receiving process is running - the value increments the count
above (sic)
The update is currently issued deep inside the rx replenish chain (see
velocity_give_many_rx_descs).
Let's propagate enough information to the caller so that the rx
replenish functions do not depend on hardware any more.
It is needed to perform the Rx/Tx buffers housekeeping when MTU changes.

Executive summary: the bounce buffers are in my way
- they use something like a 64 * 1500 bytes area of PCI
consistent area
- they are not resized when the MTU changes
- they are used
- to hand-pad undersized packets. skb_pad anyone ?
- to linearize fragmented skbs whose fragment count
goes beyond the 7 fragments hardware limit in order
to claim scatter-gather support
Actually the SG code is commented out and I wonder if it
could not be implemented (ab-)using the large send feature
of the chipset since the latter should support some
multi-descriptor packet transmitting.

- setting the address filtering registers for vlans is not
needed when there is no vlan
The non-tagged interface is filtered out as soon as a tagged

zero-tagged interface is created.

Instead of all drivers reading pci config space to get the revision
ID, they can now use the pci_device->revision member.
This exposes some issues where drivers where reading a word or a dword
for the revision number, and adding useless error-handling around the
read. Some drivers even just read it for no purpose of all.
In devices where the revision ID is being copied over and used in what
appears to be the equivalent of hotpath, I have left the copy code
and the cached copy as not to influence the driver's performance.
