Cleanup gfar_start_xmit()'s fast path by factoring out "redundant"
FCB insertion code (repeated gfar_add_fcb() calls and related)
and by reducing the number of if() clauses (i.e. if(fcb) checks).
Improve maintainability (e.g. there's less code and easier to read)
also by introducing do_csum and do_vlan to mark the other 2 Tx TOE
functionalities, following the same model as do_tstamp.
fcb_len may also be 0 now, to mark that Tx FCB insertion conditions
(do_csum, do_vlan, do_tstamp) have not been met.

Both [eTSEC76] and [eTSEC12] errata relate to Tx checksum generation
(for some MPC83xx and MCP8548 older revisions). They require the same
workaround: manual checksum computation and insertion, and disabling
the H/W Tx csum acceleration feature (per frame) through Tx FCB
(Frame Control Block) csum offload settings.
The workaround for [eTSEC76] needs to be fixed because it currently
fails to disable H/W Tx csum insertion via FCB. This patch fixes it
and provides a common workaround implementation for both Tx csum errata.

We're already protected by RTNL lock, so nothing can happen to bond/its
slaves, and thus the locking is useless here (both bond->lock and
bond->curr_active_slave).
Also, add ASSERT_RTNL() both to bond_set_rx_mode() and bond_hw_addr_swap()
to catch possible uses of it without RTNL locking.
This patch also saves us from a lockdep false-positive in
bond_set_rx_mode() vs bond_hw_addr_swap().

Currently we use a lot of time comparison math for arp_interval
comparisons, which are sometimes quite hard to read and understand.
All the time comparisons have one pattern:
(time - arp_interval_jiffies) <= jiffies <= (time + mod *
arp_interval_jiffies + arp_interval_jiffies/2)
Introduce a new helper - bond_time_in_interval(), which will do the math in
one place and, thus, will clean up the logical code. This helper introduces
a bit of overhead (by always calculating the jiffies from arp_interval),
however it's really not visible, considering that functions using it
usually run once in arp_interval milliseconds.
There are several lines slightly over 80 chars, however breaking them would
result in more hard-to-read code than several character after the 80 mark.

This change brings the suppressor attribute names into line; it also changes
the data types to provide a more consistent interface.
While -1 indicates that the suppressor is not enabled, values >= 0 for
suppress_prefixlen or suppress_ifgroup reject routing decisions violating the
constraint.
This changes the previously presented behaviour of suppress_prefixlen, where a
prefix length _less_ than the attribute value was rejected. After this change,
a prefix length less than *or* equal to the value is considered a violation of
the rule constraint.
It also changes the default values for default and newly added rules (disabling
any suppression for those).

NetLabel has the ability to selectively assign network security labels
to outbound traffic based on either the LSM's "domain" (different for
each LSM), the network destination, or a combination of both. Depending
on the type of traffic, local or forwarded, and the type of traffic
selector, domain or address based, different hooks are used to label the
traffic; the goal being minimal overhead.
Unfortunately, there is a bug such that a system using NetLabel domain
based traffic selectors does not correctly label outbound local traffic
that is not assigned to a socket. The issue is that in these cases
the associated NetLabel hook only looks at the address based selectors
and not the domain based selectors. This patch corrects this by
checking both the domain and address based selectors so that the correct
labeling is applied, regardless of the configuration type.
In order to acomplish this fix, this patch also simplifies some of the
NetLabel domainhash structures to use a more common outbound traffic
mapping type: struct netlbl_dommap_def. This simplifies some of the code
in this patch and paves the way for further simplifications in the
future.

Veaceslav Falico says:
====================
Recent patches revealed an old bug, which was there for quite awhile. It's
related to vlan on top of bonding and ndo_neigh_setup(). When vlan device
is initiated, it calls its real_dev->ndo_neigh_setup(), and in case of
bonding - it will modify neigh_parms->neigh_setup to point to
bond_neigh_init, while neigh_parms are of vlan's dev.
This way, when neigh_parms->neigh_setup() of vlan's dev is called, the
bonding function will be called, which expects the dev to be struct
bonding, but will receive a vlan dev.
It was hidden before because of bond->first_slave usage. Now, with
Nikolay's conversion to list/RCU, first_slave is gone and we hit a null
pointer dereference when working with lists/slave.
First patch moves ndo_neigh_setup() in neigh_parms_alloc() to the bottom,
so that the ->dev will be available to the caller. It doesn't really change
anything, however is needed for the second patch.
Second patch makes bond_neigh_setup() (bond->ndo_neigh_setup()) check if
the neigh_parms are really from a bonding dev, and only modify the
neigh_setup in this case.
