The ocelot switch has been supporting LAG offload since its initial
commit, however felix could not make use of that, due to lack of a LAG
abstraction in DSA. Now that we have that, let's forward DSA's calls
towards the ocelot library, who will deal with setting up the bonding.

At present there is an issue when ocelot is offloading a bonding
interface, but one of the links of the physical ports goes down. Traffic
keeps being hashed towards that destination, and of course gets dropped
on egress.
Monitor the netdev notifier events emitted by the bonding driver for
changes in the physical state of lower interfaces, to determine which
ports are active and which ones are no longer.
Then extend ocelot_get_bond_mask to return either the configured bonding
interfaces, or the active ones, depending on a boolean argument. The
code that does rebalancing only needs to do so among the active ports,
whereas the bridge forwarding mask and the logical port IDs still need
to look at the permanently bonded ports.

We can now simplify the implementation by always using ocelot_get_bond_mask
to look up the other ports that are offloading the same bonding interface
as us.
In ocelot_set_aggr_pgids, the code had a way to uniquely iterate through
LAGs. We need to achieve the same behavior by marking each LAG as visited,
which we do now by using a temporary 32-bit "visited" bitmask. This is
ok and we do not need dynamic memory allocation, because we know that
this switch architecture will not have more than 32 ports (the PGID port
masks are 32-bit anyway).

The setup of logical port IDs is done in two places: from the inconclusively
named ocelot_setup_lag and from ocelot_port_lag_leave, a function that
also calls ocelot_setup_lag (which apparently does an incomplete setup
of the LAG).
To improve this situation, we can rename ocelot_setup_lag into
ocelot_setup_logical_port_ids, and drop the "lag" argument. It will now
set up the logical port IDs of all switch ports, which may be just
slightly more inefficient but more maintainable.

The index of the LAG is equal to the logical port ID that all the
physical port members have, which is further equal to the index of the
first physical port that is a member of the LAG.
The code gets a bit carried away with logic like this:
if (a == b)
c = a;
else
c = b;
which can be simplified, of course, into:
c = b;
(with a being port, b being lp, c being lag)
This further makes the "lp" variable redundant, since we can use "lag"
everywhere where "lp" (logical port) was used. So instead of a "c = b"
assignment, we can do a complete deletion of b. Only one comment here:
if (bond_mask) {
lp = __ffs(bond_mask);
ocelot->lags[lp] = 0;
}
lp was clobbered before, because it was used as a temporary variable to
hold the new smallest port ID from the bond. Now that we don't have "lp"
any longer, we'll just avoid the temporary variable and zeroize the
bonding mask directly.

Since this code should be called from pure switchdev as well as from
DSA, we must find a way to determine the bonding mask not by looking
directly at the net_device lowers of the bonding interface, since those
could have different private structures.
We keep a pointer to the bonding upper interface, if present, in struct
ocelot_port. Then the bonding mask becomes the bitwise OR of all ports
that have the same bonding upper interface. This adds a duplication of
functionality with the current "lags" array, but the duplication will be
short-lived, since further patches will remove the latter completely.

IPv6 header information is not currently part of the entropy source for
the 4-bit aggregation code used for LAG offload, even though it could be.
The hardware reference manual says about these fields:
ANA::AGGR_CFG.AC_IP6_TCPUDP_PORT_ENA
Use IPv6 TCP/UDP port when calculating aggregation code. Configure
identically for all ports. Recommended value is 1.
ANA::AGGR_CFG.AC_IP6_FLOW_LBL_ENA
Use IPv6 flow label when calculating AC. Configure identically for all
ports. Recommended value is 1.
Integration with the xmit_hash_policy of the bonding interface is TBD.

Since switchdev/DSA exposes network interfaces that fulfill many of the
same user space expectations that dedicated NICs do, it makes sense to
not deny bonding interfaces with a bonding policy that we cannot offload,
but instead allow the bonding driver to select the egress interface in
software.

ocelot_netdevice_port_event treats a single event, NETDEV_CHANGEUPPER.
So we can remove the check for the type of event, and rename the

very similar name of ocelot_netdevice_event.

When device side MTU is larger than host side MTU, the packets
(typically rmnet packets) are split over multiple MHI transfers.
In that case, fragments must be re-aggregated to recover the packet
before forwarding to upper layer.
A fragmented packet result in -EOVERFLOW MHI transaction status for
each of its fragments, except the final one. Such transfer was
previously considered as error and fragments were simply dropped.
This change adds re-aggregation mechanism using skb chaining, via
skb frag_list.
A warning (once) is printed since this behavior usually comes from
a misconfiguration of the device (e.g. modem MTU).

have at least two byte alignment, but are annotated with a __packed attribute
to force single-byte alignment:
staging/vt6656/rxtx.h:98:1: warning: alignment 1 of 'struct vnt_rts_g' is less than 2 [-Wpacked-not-aligned]
staging/vt6656/rxtx.h:106:1: warning: alignment 1 of 'struct vnt_rts_ab' is less than 2 [-Wpacked-not-aligned]
staging/vt6656/rxtx.h:116:1: warning: alignment 1 of 'struct vnt_cts' is less than 2 [-Wpacked-not-aligned]
I see no reason why the structure itself would be misaligned, and all members
have at least two-byte alignment within the structure, so use the same
constraint on the sturcture itself.

Building this with 'make W=1' produces a couple of warnings:
rtl8723bs/include/ieee80211.h:730:1: warning: alignment 1 of 'struct ieee80211_assoc_request_frame' is less than 2 [-Wpacked-not-aligned]
rtl8723bs/include/ieee80211.h:737:1: warning: alignment 1 of 'struct ieee80211_assoc_response_frame' is less than 2 [-Wpacked-not-aligned]
The warnings are in dead code, so just remove the bits that
are obviously broken like this.

bcm2835-audio/ as well.
