MAC block supports 32 dmac filters which are logically
divided among all attached LMACS.

For example MAC block0 having one LMAC then maximum supported
filters are 32 where as MAC block1 having 4 enabled LMACS
them maximum supported filteres are 8 for each LMAC.

This patch adds mbox handlers to add/delete/update mac entry
in DMAC filter table.

dsa: mv88e6xxx: Topaz fixes

here comes some fixes for the Topaz family (Marvell 88E6141 / 88E6341)
which I found out about when I compared the Topaz' operations
structure with that one of Peridot (6390).

This is v2. In v1, I accidentally sent patches generated from wrong
branch and the 5th patch does not contain a necessary change in
serdes.c.

Changes from v1:
- the fifth patch, "enable SerDes RX stats for Topaz", needs another
  change in serdes.c
- Andrew's Reviewed-by to 1,2,3,4 and 6

Commit bf3504ce ("net: dsa: mv88e6xxx: Add 6390 family PCS

via ethtool -d for Peridot.

The same implementation is also valid for Topaz, but was not

Setting the EXT_ENERGY_DET_MASK bit allows the port energy detection
logic of the internal PHY to prevent the system from sleeping. Some
internal PHYs will report that energy is detected when the network
interface is closed which can prevent the system from going to sleep
if WoL is enabled when the interface is brought down.

Since the driver does not support waking the system on this logic,
this commit clears the bit whenever the internal PHY is powered up
and the other logic for manipulating the bit is removed since it
serves no useful function.

The DSA core has a layered structure, and even though we end up
returning 0 (success) to user space when setting a bonding/team upper
that can't be offloaded, some parts of the framework actually need to
know that we couldn't offload that.

For example, if dsa_switch_lag_join returns 0 as it currently does,
dsa_port_lag_join has no way to tell a successful offload from a
software fallback, and it will call dsa_port_bridge_join afterwards.
Then we'll think we're offloading the bridge master of the LAG, when in
fact we're not even offloading the LAG. In turn, this will make us set
skb->offload_fwd_mark = true, which is incorrect and the bridge doesn't
like it.

Dynamic LMTST region setup

This patch series allows RVU PF/VF to allocate memory for
LMTST operations instead of using memory reserved by firmware
which is mapped as device memory.
The LMTST mapping table contains the RVU PF/VF LMTST memory base
address entries. This table is used by hardware for LMTST operations.
Patch1 introduces new mailbox message to update the LMTST table with
the new allocated memory address.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>

The current driver uses static LMTST region allocated by firmware.
This memory gets populated as PF/VF BAR2. RVU PF/VF driver ioremap
the memory as device memory for NIX/NPA operation. Since the memory
is mapped as device memory we see performance degration. To address
this issue this patch implements runtime memory allocation.
RVU PF/VF allocates memory during device probe and share the base
address with RVU AF. RVU AF then configure the LMT MAP table
accordingly.

Introducing a new mailbox to support updating lmt entries
and common lmt base address scheme i.e. multiple pcifuncs
can share lmt region to reduce L1 cache pressure for application.
Parameters passed to mailbox includes the primary pcifunc
value whose lmt regions will be shared by other secondary
pcifuncs. Here secondary pcifunc will be the one who is
calling the mailbox.
For example:
By default each pcifunc has its own LMT base address:
        PCIFUNC1    LMT_BASE_ADDR A
        PCIFUNC2    LMT_BASE_ADDR B
        PCIFUNC3    LMT_BASE_ADDR C
        PCIFUNC4    LMT_BASE_ADDR D
Application will choose PCIFUNC1 as base/primary pcifunc
and as and when other pcifunc(secondary pcifuncs) gets
probed, this mailbox will be called and LMTST table will
be updated as:
        PCIFUNC1    LMT_BASE_ADDR A
        PCIFUNC2    LMT_BASE_ADDR A
        PCIFUNC3    LMT_BASE_ADDR A
        PCIFUNC4    LMT_BASE_ADDR A

On FLR lmtst map table gets resetted to the default lmt
base addresses for all secondary pcifuncs.
