GCC complains in these queue index operations because we
perform operations of the form:

	x = some_operation(++x);

which is undefined.  Replace with:

	x = some_operation(x + 1);

which is well defined and provides the intended operation.

This updates the bonding driver to support v2.6.27-rc3 enhancements
(b11f8d8c aka. "ethtool: Expand ethtool_cmd.speed to 32 bits") which
allow to encode the Mbps link speed on 32-bits (Max 4 Pbps) instead of
16 (Max 65536 Mbps).

This patch also attempts to compact struct slave by reordering its
fields.

The __get_link_speed() function returns a u16 value which was stored
in a u32 local variable. This patch uses the return value directly,
thus fixing that minor type consistency.

The 'duplex' field in struct slave being encoded on 8 bits, to be more
consistent we use a u8 integer (instead of u16) whenever we copy it to
local variables.

When physical identification of an adapter is done by toggling the
mechanism on and off through software utilizing the set_phys_id operation,
it is done with a fixed duration for both on and off states.  Some drivers
may want to set a custom duration for the on/off intervals.  This patch
changes the API so the return code from the driver's entry point when it
is called with ETHTOOL_ID_ACTIVE can specify the frequency at which to
cycle the on/off states, and updates the drivers that have already been
converted to use the new set_phys_id and use the synchronous method for
identifying an adapter.

The physical identification frequency set in the updated drivers is based
on how it was done prior to the introduction of set_phys_id.

Compile tested only.  Also fixes a compiler warning in sfc.

v2: drivers do not return -EINVAL for ETHOOL_ID_ACTIVE
v3: fold patchset into single patch and cleanup per Ben's feedback
