In case of netdev registration failure the code path will
jump to init_fail label:
init_fail:
netdev_err(ndev, "init failed\n");
moxart_mac_free_memory(ndev);
irq_map_fail:

So, there is no need to call free_netdev() before jumping
to error handling path, since it can cause UAF or double-free

IRQs are requested during driver's ndo_open() and then later
freed up in disable_interrupts() during driver unload.
A race exists where driver can set the CXGB4_FULL_INIT_DONE
flag in ndo_open() after the disable_interrupts() in driver
unload path checks it, and hence misses calling free_irq().
Fix by unregistering netdevice first and sync with driver's
ndo_open(). This ensures disable_interrupts() checks the flag
correctly and frees up the IRQs properly.

bonding has been supporting ipsec offload.
When SA is added, bonding just passes SA to its own active real interface.
But it doesn't manage SA.
So, when events(add/del real interface, active real interface change, etc)
occur, bonding can't handle that well because It doesn't manage SA.
So some problems(panic, UAF, refcnt leak)occur.
In order to make it stable, it should manage SA.
That's the reason why struct bond_ipsec is added.
When a new SA is added to bonding interface, it is stored in the
bond_ipsec list. And the SA is passed to a current active real interface.
If events occur, it uses bond_ipsec data to handle these events.
bond->ipsec_list is protected by bond->ipsec_lock.
If a current active real interface is changed, the following logic works.
1. delete all SAs from old active real interface
2. Add all SAs to the new active real interface.
3. If a new active real interface doesn't support ipsec offload or SA's
option, it sets real_dev to NULL.

There are two pointers in struct xfrm_state_offload, *dev, *real_dev.
These are used in callback functions of struct xfrmdev_ops.
The *dev points whether bonding interface or real interface.
If bonding ipsec offload is used, it points bonding interface If not,
it points real interface.
And real_dev always points real interface.
So, netdevsim should always use real_dev instead of dev.
Of course, real_dev always not be null.

The current location of the callback delete can lead to a race
condition where deleting the callback requires a write_lock on
the nf_table, but at the same time another thread from netfilter
could have taken a read lock on the table before trying to offload.
Since the driver is taking a rtnl_lock this can lead into a deadlock
situation, where the netfilter offload will wait for the cls_flower
rtnl_lock to be released, but this cannot happen since this is
waiting for the nf_table read_lock to be released before it can
delete the callback.
Solve this by completely removing the nf_flow_table_offload_del_cb
call, as this will now be cleaned up by act_ct itself when cleaning
up the specific nf_table.

Normally, if a reset fails due to failover or other communication error
there is another reset (eg: FAILOVER) in the queue and we would process
that reset. But if we are unable to communicate with PHYP or VIOS after
H_FREE_CRQ, there would be no other resets in the queue and the adapter
would be in an undefined state even though it was in the OPEN state
earlier. While starting the reset we set the carrier to off state so
we won't even get the timeout resets.
If the last queued reset fails, retry it as a hard reset (after the
usual 60 second settling time).

DMAC filtering can be achieved by either NPC MCAM rules or
CGX/RPM MAC filters. Currently we are achieving this by NPC
MCAM rules. This patch offloads DMAC filters to CGX/RPM MAC
filters instead of NPC MCAM rules. Offloading DMAC filter to
CGX/RPM block helps in reducing traffic to NPC block and
save MCAM rules

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.

Commit bf3504cea7d7e ("net: dsa: mv88e6xxx: Add 6390 family PCS
registers to ethtool -d") added support for dumping SerDes PCS registers
via ethtool -d for Peridot.
The same implementation is also valid for Topaz, but was not
enabled at the time.

Commit 0df952873636a ("mv88e6xxx: Add serdes Rx statistics") added
support for RX statistics on SerDes ports for Peridot.
This same implementation is also valid for Topaz, but was not enabled
at the time.
We need to use the generic .serdes_get_lane() method instead of the
Peridot specific one in the stats methods so that on Topaz the proper
one is used.

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.
