====================
NFC 4.6 pull request
This is a very small one this time, with only 5 patches.
There are a couple of big items that could not be merged/finished
on time.
We have:
- 2 LLCP fixes for a race and a potential OOM.
- 2 cleanups for the pn544 and microread drivers.
- 1 Maintainer addition for the s3fwrn5 driver.

This is an implementation of MACsec/IEEE 802.1AE. This driver
provides authentication and encryption of traffic in a LAN, typically
with GCM-AES-128, and optional replay protection.

When operating the at803x in SGMII mode, resuming the chip
from power down brings up the copper-side link but leaves
the SGMII link in unconnected state (tested with at8031
attached to gianfar). In effect, this caused a permanent
link loss once the related interface was put down.
This patch ensures that power down handling in supspend()
and resume() is also applied to the SGMII link.

Bulk free of SKBs happen transparently by the API call napi_consume_skb().
The napi budget parameter is needed by napi_consume_skb() to detect

Bulk free of SKBs happen transparently by the API call napi_consume_skb().
The napi budget parameter is usually needed by napi_consume_skb()
to detect if called from netpoll. In this patch it has an extra meaning.
For mlx4 driver, the mlx4_en_stop_port() call is done outside
NAPI/softirq context, and cleanup the entire TX ring via
mlx4_en_free_tx_buf(). The code mlx4_en_free_tx_desc() for
freeing SKBs are shared with NAPI calls.
To handle this shared use the zero budget indication is reused,
and handled appropriately in napi_consume_skb(). To reflect this,
variable is called napi_mode for the function call that needed
this distinction.

For pcie nic, after setting link speed and there is no link driver does not need
to do phy reset until link up.
For some pcie nics, to do this will also reset phy speed down counter and prevent
phy from auto speed down.
This patch fix the issue reported in following link.

Firmware now tells us that the reset is done by passing a magic value
via register. Use it to shorten the wait in case this is supported.
With old firmware, we still wait until the timeout is reached.

On AT91 SoCs, the User Register (USRIO) exposes a switch to configure the
"Reduced" or "Traditional" version of the Media Independent Interface
(RMII vs. MII or RGMII vs. GMII).
As on the older EMAC version, on GMAC, this switch is set by default to the
non-reduced type of interface, so use the existing capability and extend it to
GMII as well. We then keep the current logic in the macb_init() function.
The capabilities of sama5d2, sama5d4 and sama5d3 GEM interface are updated in
the macb_config structure to be able to properly enable them with a traditional
interface (GMII or MII).

Remove the "prepare for reconnect" pr_info in xenbus.c. It's largely
uninteresting and the states of the frontend and backend can easily be
observed by watching the (o)xenstored log.

The code does not currently support a frontend passing multiple extra info
fragments to the backend in a tx request. The xenvif_get_extras() function
handles multiple extra_info fragments but make_tx_response() assumes there
is only ever a single extra info fragment.
This patch modifies xenvif_get_extras() to pass back a count of extra
info fragments, which is then passed to make_tx_response() (after
possibly being stashed in pending_tx_info for deferred responses).

The Raspberry Pi Foundation's firmware updates are shipping device
trees using the old string, so we'll keep recognizing that as this rev
of V3D. Still, we should use a more specific name in the upstream DT
to clarify which board is being supported, in case we do other revs of
V3D in the future.

This class supports a WFI method (0x0078) that's not present on the
KeplerChannelGpfifoA class.
The binary driver exposes both classes on these GPUs for some reason,
though there doesn't appear to be any difference in the setup that's
done for each (ie. even if you allocate GpfifoA, the WFI method will
still work).
We shall just expose GpfifoB, as I don't see a good reason to report
the presence of both.
