On all targets that sucker boils down to memcpy_fromio(sbk->data, from, len).
The function name is highly misguiding (it _never_ does any checksums), the
last argument is just a noise and simply expanding the call to memcpy_fromio()
gives shorter and more readable source. For a lot of reasons it has almost
no remaining users, so it's better to just outright kill it.

ucc_geth: Add support to local-mac-address property
ucc_geth: Remove obsolete workaround of link speed change
cxgb3: sysfs attributes in -mm tree
Add Attansic L1 ethernet driver.
IEEE-1275 defines “local-mac-address” to be a standard
property name to specify preassigned network address.
This patch adds support for it.

During an oprofile session of linux-2.6.20 on a dual opteron system, I noticed
an expensive divide was done in tg3_poll().
I am using gcc-4.1.1, so the following comment from drivers/net/tg3.c seems
over-optimistic :
/* Do not place this n-ring entries value into the tp struct itself,
* we really want to expose these constants to GCC so that modulo et
* al. operations are done with shifts and masks instead of with
* hw multiply/modulo instructions. Another solution would be to
* replace things like '% foo' with '& (foo - 1)'.
