Do not cancel scan in disconnect callback. If there is an active scan,
it will be cancelled by firmware, then host driver will be properly
notified by event.
Cancelling scan in disconnect callback occasionally may lead to the
following race issue. Host is able to queue one scan after scan
abort in disconnect callback, and another scan after scan abort
in event handler. As a result, firmware receives second scan

Now with wlcore using PM runtime, we can also add support for Linux
generic wakeirq handling for it if configured in the dts file.
The wakeirq can be configured as the second interrupt in the dts file
with interrupts-extended property where it is the padconf irq of the OOB
GPIO pin used for wlcore interrupt.
Note that eventually we should also allow configuring wlcore to use the
SDIO dat1 IRQ for wake-up, and in that case the the wakeirq should be
configured to be the padconf interrupt of the dat1 pin and not the
padconf interrupt of the OOB GPIO pin.

The driver sends an action frame down and waits for a completion signal
triggered by the received BRCMF_E_ACTION_FRAME_OFF_CHAN_COMPLETE event
to continue the process. However, the action frame could be transmitted
either on the current channel or on an off channel. For the on-channel
case, only BRCMF_E_ACTION_FRAME_COMPLETE event will be received when
the frame is transmitted, which make the driver always wait a full
timeout duration. This patch has the completion signal be triggered by
receiving the BRCMF_E_ACTION_FRAME_COMPLETE event for the on-channel
case.

Presently, for non-zero copy case, separate pages are allocated for
storing plaintext and encrypted text of records. These pages are stored
in sg_plaintext_data and sg_encrypted_data scatterlists inside record
structure. Further, sg_plaintext_data & sg_encrypted_data are passed
to cryptoapis for record encryption. Allocating separate pages for
plaintext and encrypted text is inefficient from both required memory
and performance point of view.
This patch adds support of inplace encryption of records. For non-zero
copy case, we reuse the pages from sg_encrypted_data scatterlist to
copy the application's plaintext data. For the movement of pages from
sg_encrypted_data to sg_plaintext_data scatterlists, we introduce a new
function move_to_plaintext_sg(). This function add pages into
sg_plaintext_data from sg_encrypted_data scatterlists.
tls_do_encryption() is modified to pass the same scatterlist as both
source and destination into aead_request_set_crypt() if inplace crypto
has been enabled. A new ariable 'inplace_crypto' has been introduced in
record structure to signify whether the same scatterlist can be used.
By default, the inplace_crypto is enabled in get_rec(). If zero-copy is
used (i.e. plaintext data is not copied), inplace_crypto is set to '0'.

Similar to other patches from ERic.
As diagnosed by Song Liu, ndo_poll_controller() can
be very dangerous on loaded hosts, since the cpu
calling ndo_poll_controller() might steal all NAPI
contexts (for all RX/TX queues of the NIC). This capture
can last for unlimited amount of time, since one
cpu is generally not able to drain all the queues under load.
In netvsc driver it uses NAPI for TX completions. The default
poll_napi will do this for us now and avoid the capture.

dpaa2-eth: Add support for Rx flow classification
The Management Complex (MC) firmware initially allowed the
configuration of a single key to be used both for Rx flow hashing
and flow classification. This prevented us from supporting
Rx flow classification independently of the hash key configuration.
Newer firmware versions expose separate commands for
configuring the two types of keys, so we can use them to
introduce Rx classification support. For frames that don't match
any classification rule, we fall back to statistical distribution
based on the current hash key.
The first patch in this set updates the Rx hashing code to use
the new firmware API for key config. Subsequent patches introduce
the firmware API for configuring the classification and actual
support for adding and deleting rules via ethtool.

Add support for inserting and deleting Rx flow classification
rules through ethtool.
We support classification based on some header fields for
flow-types ether, ip4, tcp4, udp4 and sctp4.
Rx queues are core affine, so the action argument effectively
selects on which cpu the matching frame will be processed.
Discarding the frame is also supported.

For firmware versions that support it, configure an Rx flow
classification key at probe time.
Hardware expects all rules in the classification table to share
the same key. So we setup a key containing all supported fields
at driver init and when a user adds classification rules through
ethtool, we will just mask out the unused header fields.
Since the key composition process is the same for flow
classification and hashing, reuse existing code where possible.
