This change removes use of constants for rx buffer queue size
and instead calculates the queue length based on what he MTU
is set to.

This network device driver shares the same hardware as the qla4xxx
iSCSI driver. Changing the MTU via the device interface will
cause qla4xxx to crash as there is no way to make notification.
Users wishing to change the MTU must do so using an iSCSI
utility such as Qlogic SanSurfer. This forces the user to
unload/reload this network device driver after the MTU
value has been changed in flash.

We do not need to zero out the 64 byte MAC request I/O control block.
  By zeroing out the control block and setting it to proper fields is
redundant work.  This is because in the qla3xxx_send() function we will
already set the proper fields in this structure.  The unused fields are
not looked at by the hardware and do not need to be zeroed out.

The return code was not properly set when when allocating memory or mapping
memory failed.  Depending on the stack, the return code would sometimes
return 0, which indicates everything was ok, when in fact there was an error.
  This would cause trouble when the module was removed.  Now, we will pass
back the proper return code when an error occurs during the PCI probe.

The driver contains this little piece of candy:

#if defined(CONFIG_DMA_NONCOHERENT) || defined(CONFIG_NOT_COHERENT_CACHE)
#define ETH_DMA_ALIGN           L1_CACHE_BYTES
#else
#define ETH_DMA_ALIGN           8
#endif

Any reason why we're not using dma_get_cache_alignment() instead?

It looks like the skge driver inherited another bug from the sk98lin code.
If I send from 1000mbit port to a machine on 100mbit port, the switch should
be doing hardware flow control, but no pause frames show up in the statistics.

This is the analog of the recent sky2 fixes. The device needs to listen
for multicast pause frames and then not discard them.

This version moves the medium variable to the card specific structure and
changes the GMII_* to BCM54XX_* #defines.

This patch adds improved version of enable_fiber for both the 5421 and
the 5461 phy. It is now possible to specify with these wether you want
autonegotiation or not. This is needed for bladecenter switches where
some expect autonegotiation and some dont seem to like this at all.
Depending on this flag it sets phy->autoneg accordingly for the fiber mode.

More importantly it implements proper read_link and poll_link functions
for both phys which can handle both copper and fiber mode by determining
the medium first and then branching to the required functions. For fiber
they all work fine, for copper they are not tested but return the result
of the genmii_* function anyway which is supposed to work.

The patch moves the genmii_* functions around to avoid foreward declarations.
