net: phy: mxl-gpy: version fix and improvements
Fix the version reporting which was introduced earlier. The version will
not change during runtime, so cache it and save a PHY read on every auto

Now having a major and a minor number, also print the firmware in
human readable form "major.minor". Still keep the 4-digit hexadecimal
representation because that form is used in the firmware changelog
documents. Also, drop the "release" string assuming that most common
case, but make it clearer that the user is running a test version.

net: marvell: prestera: add MDB offloading support
This patch series adds support for the MDB handling for the marvell
Prestera Driver. It's used to propagate IGMP groups registered within
the Kernel to the underlying HW (offload registered groups).
Features:
- define (and implement) main internal MDB-related objects;
- define (and implement) main HW APIs for MDB handling;
- add MDB handling support for both regular ports as well as Bond
interfaces;
- Mirrored behavior of Bridge driver upon multicast router appearance
(all traffic flooded when there's no mcast router; mcast router
receives all mcast traffic, and only group-specific registered mcast
traffic is being received by ports who've explicitly joined any group
when there's a registered mcast router);
- Reworked prestera driver bridge flags (especially multicast)
setting - thus making it possible to react over mcast disabled messages
properly by offloading this state to the underlying HW
(disabling multicast flooding);
Limitations:
- Not full (partial) IGMPv3 support (due to limited switchdev
notification capabilities:
MDB events are being propagated only with a single MAC entry,
while IGMPv3 has Group-Specific requests and responses);
- It's possible that multiple IP groups would receive traffic from
other groups, as MDB events are being propagated with a single MAC
entry, which makes it possible to map a few IPs over same MAC;

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.

When building with Clang we encounter these warnings:
| drivers/net/ethernet/qlogic/qed/qed_dev.c:416:30: error: format

| specifies type 'char' but the argument has type 'int' [-Werror,-Wformat]
| p_llh_info->num_ppfid - 1);
For the first warning, `i` is a u32 which is much wider than the format
specifier `%hhd` describes. This results in a loss of bits after 2^7.
The second warning involves implicit integer promotion as the resulting
type of addition cannot be smaller than an int.
example:
``
uint8_t a = 4, b = 7;
int size = sizeof(a + b - 1);
printf("%d\n", size);
// output: 4
```
See more:
(https://wiki.sei.cmu.edu/confluence/display/c/INT02-C.+Understand+integer+conversion+rules)
"Integer types smaller than int are promoted when an operation is
performed on them. If all values of the original type can be represented
as an int, the value of the smaller type is converted to an int;
otherwise, it is converted to an unsigned int."

bnxt_reinit_after_abort() is called during ifup when a previous
FW reset sequence has aborted or a previous ifup has failed after
detecting FW reset. In all cases, it is safe to assume that a
previous FW reset has completed and the driver may not have fully
reinitialized.
Prior to this patch, it is assumed that the
FUNC_DRV_IF_CHANGE_RESP_FLAGS_HOT_FW_RESET_DONE flag will always be
set by the firmware in bnxt_hwrm_if_change(). This may not be true if
the driver has already attempted to register with the firmware. The
firmware may not set the RESET_DONE flag again after the driver has
registered, assuming that the driver has seen the flag already.
Fix it to always go through the FW reset initialization path if
the BNXT_STATE_FW_RESET_DET flag is set. This flag is always set
by the driver after successfully going through bnxt_reinit_after_abort().
