net: marvell: prestera: implement software MDB entries allocation
Define bridge MDB entry (software entry):
- entry that get's created upon receiving MDB management events
(create/delete), that inherently defines a software entry,
which can be enabled (offloaded to the HW) or disabled (removed
from HW).
This separation is done to achieve a better highlevel
management of HW resources - software MDB entry could exist,
while it's not necessarily should be configured on the HW.
For example: by default, the Linux behavior would not replicate
multicast traffic to multicast group members if there's no
active multicast router and thus - no actual multicast traffic
can be received/sent. So, until multicast router appears on the
system no HW configuration should be applied, although SW MDB entries
should be tracked.
Another example would be altering state of 'multicast enabled' on
the bridge: MC_DISABLED should invoke disabling / clearing multicast
groups of specified bridge on the HW, yet upon receiving 'multicast
enabled' event, driver should reconfigure any existing software MDB
groups on the HW.
Keeping track of software MDB entries in such way makes it possible
to properly react on such events.
Define bridge MDB port entry (software entry):
- entry that helps keeping track (on software - driver - level) of which
bridge mebemer interface joined any give MDB group;

net: marvell: prestera: Use dscp_t in struct prestera_kern_fib_cache
Use the new dscp_t type to replace the kern_tos field of struct
prestera_kern_fib_cache. This ensures ECN bits are ignored and makes it
compatible with the dscp fields of struct fib_entry_notifier_info and
struct fib_rt_info.
This also allows sparse to flag potential incorrect uses of DSCP and
ECN bits.
