If wol state of phy hardware is enabled after reset, phy_ethtool_get_wol()
returns that wol.wolopts is true.
However, since net_device.wol_enabled is zero and this doesn't apply wol
state until calling ethtool_set_wol(), so mdio_bus_phy_may_suspend()
returns true, that is, it's in a state where phy can suspend even though
wol state is enabled.
In this inconsistency, phy_suspend() returns -EBUSY, and at last,
suspend sequence fails with the following message:
dpm_run_callback(): mdio_bus_phy_suspend+0x0/0x58 returns -16
PM: Device 65000000.ethernet-ffffffff:01 failed to suspend: error -16
PM: Some devices failed to suspend, or early wake event detected
In order to fix the above issue, this patch forces to set initial wol state
to disabled as default.

The response for a SNMP request can consist of multiple parts, which
the cmd callback stages into a kernel buffer until all parts have been
received. If the callback detects that the staging buffer provides
insufficient space, it bails out with error.
This processing is buggy for the first part of the response - while it
initially checks for a length of 'data_len', it later copies an
additional amount of 'offsetof(struct qeth_snmp_cmd, data)' bytes.
Fix the calculation of 'data_len' for the first part of the response.
This also nicely cleans up the memcpy code.

Instead of freeing the RX buffers, release them back into the pool.
We wait for the maximum number of buffers supported by a single
release command to accumulate before issuing the command.
Also, don't unmap the Rx buffers at the beginning of the Rx routine
anymore, since that would require remapping them before release.
Instead, just do a DMA sync at first and only unmap if the frame is
meant for the stack.

The message buffer RAM area is not a contiguous 1KB area but 2 partitions
of 512 bytes each. Till now, we used Message buffers with payload size 8
bytes, which translates to 32 MBs per partition and no spare space is left
in any partition.
However, in upcoming SOC LX2160A the message buffers can have payload size
64 bytes. This results in less than 32 MBs per partition and some empty
area is left at the end of each partition.This empty area should not be
accessed.
Therefore, split the Message Buffer RAM area into two partitions.

Till now the flexcan module supported 8 byte payload size as per CAN 2.0
specifications. But now upcoming flexcan module in NXP LX2160A SOC

Therefore, added provision in the driver for payload size to be 64 bytes.

rx offload depends on number of message buffers, which in turn depends
on messgae buffer size. with the upcoming LX2160A SOC the message buffer
size can be configured to 72 bytes if it were to be used in CAN FD mode.
The current mode in which the flexcan is being operated is known at the
time of flexcan_open() but not at the time of flexcan_probe().
Therefore, move the rx_offload_add() from flexcan_probe() to
flexcan_open(). correspondingly, move rx_offload_delete() from
flexcan_remove() to flexcan_close().

There is no expression deactivation call from the rule replacement path,
hence, chain counter is not decremented. A few steps to reproduce the
problem:
%nft add table ip filter
%nft add chain ip filter c1
%nft add chain ip filter c1
%nft add rule ip filter c1 jump c2
%nft replace rule ip filter c1 handle 3 accept
%nft flush ruleset
<jump c2> expression means immediate NFT_JUMP to chain c2.
Reference count of chain c2 is increased when the rule is added.
When rule is deleted or replaced, the reference counter of c2 should be
decreased via nft_rule_expr_deactivate() which calls
nft_immediate_deactivate().
