Prevent setting of devlink traps on the uplink while in switchdev mode.
In this mode, it is the SW switch responsibility to handle both packets
with a mismatch in destination MAC or VLAN ID. Therefore, there are no
flow steering tables to trap undesirable packets and driver crashes upon
setting a trap.

This reverts commit 9c63faaa931e443e7abbbee9de0169f1d4710546, which
introduces a suspend/resume regression on Jetson TX2 boards that can be
reproduced every time. Given that the issue that this was supposed to
fix only occurs very sporadically the safest course of action is to
revert before v5.12 and then we can have another go at fixing the more
rare issue in the next release (and perhaps backport it if necessary).
The root cause of the observed problem seems to be that when the system
is suspended, some packets are still in transit. When the descriptors
for these buffers are cleared on resume, the descriptors become invalid
and cause a fatal bus error.

Normally, the bootloader will already initialize the MAC address
registers of the ENETC and the driver will just use them or generate a
random one, if it is not initialized.
Add a new way to provide the MAC address: via device tree. Besides the
usual 'mac-address' property, there is also the possibility to fetch it
via a NVMEM provider. The sl28 board stores the MAC address in the SPI
NOR flash OTP region. Having this will allow linux to fetch the MAC
address from there without being dependent on the bootloader.
No in-tree boards have the device tree properties set, thus for these,
this is a no-op.

Commit a14d273ba159 ("net: macb: restore cmp registers on resume path")
introduces the restore of CMP registers on resume path. In case the IP
doesn't support type 2 screeners (zero on DCFG8 register) the
struct macb::rx_fs_list::list is not initialized and thus the
list_for_each_entry(item, &bp->rx_fs_list.list, list) loop introduced in
commit a14d273ba159 ("net: macb: restore cmp registers on resume path")
will access an uninitialized list leading to crash. Thus, initialize
the struct macb::rx_fs_list::list without taking into account if the
IP supports type 2 screeners or not.

During cotable resize we pin the backup buffer to make sure the
trylock doesn't fail. We were never unpinning the backup buffer
resulting in every subsequent cotable resize trying to release a
pinned bo. After we copy the old backup to the new we can release
the pin.
Mob's are always pinned so we just have to make sure we unpin
them before releasing them.

We were not correctly unpinning no longer needed buffers. In particular
vmw_buffer_object, which is internally often pinned on creation wasn't
unpinned on destruction and none of the internal MOB buffers were
unpinned before being put back. Technically this existed for a
long time but commit 57fcd550eb15 ("drm/ttm: Warn on pinning without
holding a reference") introduced a WARN_ON which was filling up the
kernel logs rather quickly.
Quite frankly internal usage of vmw_buffer_object and in general
pinning needs to be refactored in vmwgfx but for now this makes
it work.

__ibmvnic_open calls napi_disable without checking whether NAPI polling
has already been disabled or not. This could cause napi_disable
being called twice, which could generate deadlock. For example,
the first napi_disable will spin until NAPI_STATE_SCHED is cleared
by napi_complete_done, then set it again.
When napi_disable is called the second time, it will loop infinitely
because no dev->poll will be running to clear NAPI_STATE_SCHED.
To prevent above scenario from happening, call ibmvnic_napi_disable()
which checks if napi is disabled or not before calling napi_disable.

Setting 10G without autonegotiation is invalid according to
phy_ethtool_ksettings_set(). Thus, we need to set it during
autonegotiation.
If 1G autonegotiation can't complete for quite a time, but there is
signal in line, switch line interface type to 10GBase-R, if supported,
in hope for link to be established.
And vice versa. If 10GBase-R link can't be established for quite a time,
and autonegotiation is enabled, and there is signal in line, switch line
interface type to appropriate 1G mode, i.e. 1000Base-X or SGMII, if

commit df7b59ba9245 ("dm verity: fix FEC for RS roots unaligned to
block size") introduced the possibility for misaligned roots IO
relative to the underlying device's logical block size. E.g. Android's
default RS roots=2 results in dm_bufio->block_size=1024, which causes
the following EIO if the logical block size of the device is 4096,
given v->data_dev_block_bits=12:
E sd 0 : 0:0:0: [sda] tag#30 request not aligned to the logical block size
E blk_update_request: I/O error, dev sda, sector 10368424 op 0x0:(READ) flags 0x0 phys_seg 1 prio class 0
E device-mapper: verity-fec: 254:8: FEC 9244672: parity read failed (block 18056): -5
Fix this by onlu using f->roots for dm_bufio blocksize IFF it is
aligned to v->data_dev_block_bits.

Currently each packet inserted in eswitch is tagged with a internal
metadata to indicate source vport. Metadata tagging is not always
needed. Metadata insertion is needed for multi-port RoCE, failover
between representors and stacked devices. In many other cases,
metadata enablement is not needed.
Metadata insertion slows down the packet processing rate of the E-switch
when it is in switchdev mode.
Below table show performance gain with metadata disabled for VXLAN
offload rules in both SMFS and DMFS steering mode on ConnectX-5 device.
----------------------------------------------
| steering | metadata | pkt size | rx pps |
| mode | | | (million) |
----------------------------------------------
| smfs | disabled | 128Bytes | 42 |
----------------------------------------------
| smfs | enabled | 128Bytes | 36 |
----------------------------------------------
| dmfs | disabled | 128Bytes | 42 |
----------------------------------------------
| dmfs | enabled | 128Bytes | 36 |
----------------------------------------------
Hence, allow user to disable metadata using driver specific devlink
parameter. Metadata setting of the eswitch is applicable only for the
switchdev mode.
Example to show and disable metadata before changing eswitch mode:
$ devlink dev param show pci/0000:06:00.0 name esw_port_metadata
pci/0000:06:00.0:
name esw_port_metadata type driver-specific
values:
cmode runtime value true
$ devlink dev param set pci/0000:06:00.0 \
name esw_port_metadata value false cmode runtime
