Get rid of dubious casts to (void *) which causes a sparse warning.
And move largeish function from inline to the one file that uses the code,
the compiler can then decide to inline it.

The 82550 & 51 parts have an extended configuration block that
includes a bit "GMRC", required to enable the expected TCO behavior,
in config byte offset 22d.  The config block sent by the failing driver
does include the extension area, but this bit is not initialised,
and the downlaod only specifies 0x16 bytes to be sent to the NIC
(thaht's bytes 00..21d). By initializing the GMRC bit, and extending
the download size for D102+ MACs, the problem is resolved.

We intend this patch to improve spidernet interrupt handling to be
more strict.  We had following problem and this patch solves it.

 -when CONFIG_DEBUG_SHIRQ=y, request_irq() calls handler().
 -when spider_net_open() is called, it calls request_irq() which calls
  spider_net_interrupt().
 -if some specific interrupt bit is set at this timing, it calls
  netif_rx_schedule() and spider_net_poll() is scheduled.
 -spider_net_open() calls netif_poll_enable() which clears the bit
  __LINK_STATE_RX_SCHED.
 -when spider_net_poll() is called, it calls netif_rx_complete() which
  causes BUG_ON() because __LINK_STATE_RX_SCHED is not set.

The 3cSOHO100-TX needs a mdio_sync() before mdio_read() to read the MII
transceiver registers properly.  Adding EXTRA_PREAMBLE to drv_flags of the
3cSOHO100-TX will force this.

This problem exists already for years (I checked back to 2.6.8).
Setting duplex for the 3cSOHO100-TX was more or less a random process.
Till 2.6.15 it was more likely that the diver ends up in half
duplex mode, after the code change in 2.6.16 it was more likely
to end up in full duplex mode. I wonder why nobody noticed this earier.

Hopefully addresses

Add rudimentary check for the case that the page table overflows due to
merging of s/g elements by the IOMMU.  This would have lead to
overwriting of arbitrary memory.

After this change I expect that an offending command will be

core.  It's a border case and not worth to implement a recovery
