This tries to fix priority inversion in the below condition resulting in
long checkpoint delay.
f2fs_get_node_info()
- nat_tree_lock
-> sleep to grab journal_rwsem by contention
checkpoint
- waiting for nat_tree_lock
In order to let checkpoint go, let's release nat_tree_lock, if there's a
journal_rwsem contention.

misc command doesn't do npu_init before sending to firmware, so
it's possible that npu will be turned off while npu firmware is
handling misc commands which causes times out in host driver.
To fix this issue, npu_init/npu_deinit need to be called before
and after misc commands are handled. In addition, only one misc
command should be handled at any moment. The misc command should
be failed right away while the other one is being handled.

* Setting and getting 64bit packet numbers with of SAs.
* Setting (only on SA creation) and getting ssci of SAs.
* Setting salt when installing a SAK.
Added 2 cipher suite identifiers according to 802.1AE-2018 table 14-1:
* MACSEC_CIPHER_ID_GCM_AES_XPN_128
* MACSEC_CIPHER_ID_GCM_AES_XPN_256
In addition, added 2 new netlink attribute types:
* MACSEC_SA_ATTR_SSCI
* MACSEC_SA_ATTR_SALT

Support extended packet number cipher suites (802.1AEbw) frames handling.
This does not include the needed netlink patches.
* Added xpn boolean field to `struct macsec_secy`.
* Added ssci field to `struct_macsec_tx_sa` (802.1AE figure 10-5).
* Added ssci field to `struct_macsec_rx_sa` (802.1AE figure 10-5).
* Added salt field to `struct macsec_key` (802.1AE 10.7 NOTE 1).
* Created pn_t type for easy access to lower and upper halves.
* Created salt_t type for easy access to the "ssci" and "pn" parts.
* Created `macsec_fill_iv_xpn` function to create IV in XPN mode.
* Support in PN recovery and preliminary replay check in XPN mode.
In addition, according to IEEE 802.1AEbw figure 10-5, the PN of incoming
frame can be 0 when XPN cipher suite is used, so fixed the function
`macsec_validate_skb` to fail on PN=0 only if XPN is off.

MACsec offloading to underlying hardware devices is disabled by default
(the software implementation is used). This patch adds support for
changing this setting through the MACsec netlink interface. Many checks
are done when enabling offloading on a given MACsec interface as there
are limitations (it must be supported by the hardware, only a single
interface can be offloaded on a given physical device at a time, rules
can't be moved for now).

This patch introduces the MACsec hardware offloading infrastructure.
The main idea here is to re-use the logic and data structures of the
software MACsec implementation. This allows not to duplicate definitions
and structure storing the same kind of information. It also allows to
use a unified genlink interface for both MACsec implementations (so that
the same userspace tool, `ip macsec`, is used with the same arguments).
The MACsec offloading support cannot be disabled if an interface
supports it at the moment.
The MACsec configuration is passed to device drivers supporting it
through macsec_ops which are called from the MACsec genl helpers. Those
functions call the macsec ops of PHY and Ethernet drivers in two steps:
a preparation one, and a commit one. The first step is allowed to fail
and should be used to check if a provided configuration is compatible
with the features provided by a MACsec engine, while the second step is
not allowed to fail and should only be used to enable a given MACsec
configuration. Two extra calls are made: when a virtual MACsec interface
is created and when it is deleted, so that the hardware driver can stay
in sync.
The Rx and TX handlers are modified to take in account the special case
were the MACsec transformation happens in the hardware, whether in a PHY
or in a MAC, as the packets seen by the networking stack on both the
physical and MACsec virtual interface are exactly the same. This leads
to some limitations: the hardware and software implementations can't be
used on the same physical interface, as the policies would be impossible
to fulfill (such as strict validation of the frames). Also only a single
virtual MACsec interface can be offloaded to a physical port supporting
hardware offloading as it would be impossible to guess onto which
interface a given packet should go (for ingress traffic).
Another limitation as of now is that the counters and statistics are not
reported back from the hardware to the software MACsec implementation.
This isn't an issue when using offloaded MACsec transformations, but it
should be added in the future so that the MACsec state can be reported
to the user (which would also improve the debug).

underlying device (phydev for now).

Currently when dtr high is send by the host, dsr high should be
sent by the device by performing a term io to acm conversion.
But if dtr high is received twice, serial state which is converted
to acm signal is again converted, leading to serial state becoming
null. Fix this by clearing ACM bits from previous conversion before
performing uart to acm conversion.

If the net dev init process is scheduled out in between registering
a callback for in-channel and out-channel and start command for these
channels gets processed at this time (after registering the callback
for out channel but before registeringthe callback for in-channel)
then with existing logic, we never register with the network interface.
Checking the out channel status directly rather than using local bool
variable out_channel_started before calling
mhi_dev_net_open_chan_create_netif API. If out channel status is
connected the mhi_dev_net_open_chan_create_netif API is called.

M0 (mhi resume) processing and doorbell interrupt processing are done
in different contexts. And there can be a chance that DB processing
can proceed even before the resume is completely done.
Say while processing M0, MHI has issued M0-ack but not updated channel
state to running state for *all* channels yet. The host can start ringing
DB the moment it sees M0-ack and it's the channel is in running state.
To avoid this race condition, ensure MHI doesn't process any CHDB
interrupt until it's completely done with the resume.
