Previously, IPv6 extension header parsing was disabled for all devices
supported by e1000e when using packet split mode. However, as per a
silicon errata, only certain devices need this restriction and will need
to disable IPv6 extension header parsing for all modes.

Secondary unicast and multicast addresses are added to the Receive
Address registers (RAR) for most parts supported by the driver. For
82579, there is only one actual RAR and a number of Shared Receive Address
registers (SHRAR) that are shared among the driver and f/w which can be
reserved and write-protected by the f/w. On this device, use the SHRARs
that are not taken by f/w for the additional addresses.
Add a MAC ops function pointer infrastructure (similar to other MAC
operations in the driver) for setting RARs, introduce a new rar_set
function for 82579 and convert the existing code that sets RARs on other
devices to a generic rar_set function.

Replace occurrences of 'if (<bool expr> == <1|0>)' with
'if ([!]<bool expr>)'
Replace occurrences of '<bool var> = (<non-bool expr>) ? true : false'
with '<bool var> = <non-bool expr>'.
Replace occurrence of '<bool var> = <non-bool expr>' with
'<bool var> = !!<non-bool expr>'
While the latter replacement is not really necessary, it is done here for
consistency and clarity. No functional changes.

Rename e1000e_reload_nvm() to e1000e_reload_nvm_generic() to signify the

MAC ops function pointer to be consistent with the driver design.

Rename e1000e_setup_link() to e1000e_setup_link_generic() to signify the
function is used for more than one MAC-family type. The 82571-family has
a custom setup_link function which also calls the generic function. The
ich8lan-family has a custom function which should just be called via the
function pointer. The 80003es2lan-family just uses the generic function.

Rename e1000e_id_led_init() to e1000e_id_led_init_generic() to signify the
function is used for more than one MAC-family type. For the ich8lan MAC
family, some MACs use the generic function and others use the function
e1000_id_led_init_pchlan(). In all cases where e1000e_id_led_init() was
called directly, change to call the function pointer to be consistent with
the driver design.

Per ./Documentation/CodingStyle, goto statements are acceptable for the
centralized exiting of functions when there are multiple exit points which
share common work such as cleanup. When no common work is required for
multiple exit points, the function should just return at these exit points
instead of doing an unnecessary jump to a centralized return. This patch
cleans up the inappropriate use of goto statements, and removes unnecessary
variables (or move to a smaller scope) where possible as a result of the
cleanups.

The e1000_init_mac_params_XXX() functions (where XXX is one of the three
MAC-family types 80003es2lan, 82571 and ich8lan) was not meant to require a
pointer to the adapter struct but does require a pointer to the hw struct.
Pass that pointer in to the functions instead.
