Petri Gynther 8d88c6ebb3 net: bcmgenet: enable MoCA link state change detection
Currently, MoCA fixed PHYs are always in link-up state, regardless of
whether the link is actually up or not.

Add code to properly detect MoCA link state changes and to reflect the
new state in MoCA fixed PHY. Only GENET V3 and V4 MACs are capable of
detecting MoCA link state changes.

The code works as follows:
1. GENET MAC detects MoCA link state change and issues UMAC_IRQ_LINK_UP
   or UMAC_IRQ_LINK_DOWN interrupt.
2. Link up/down interrupt is processed in bcmgenet_irq_task(), which
   calls phy_mac_interrupt().
3. phy_mac_interrupt() updates the fixed PHY phydev->link and kicks
   the PHY state machine.
4. PHY state machine proceeds to read the fixed PHY link status
   register.
5. When the fixed PHY link status register is being read, the new
   function bcmgenet_fixed_phy_link_update() gets called. It copies
   the fixed PHY phydev->link value to the fixed PHY status->link.
6. PHY state machine receives the new link state of the fixed PHY.
7. MoCA fixed PHY link state now correctly reflects the real MoCA
   hardware link state.

Uwe Kleine-König 687908c2b6 net: phy: at803x: simplify using devm_gpiod_get_optional and its 4th argument
Since 39b2bbe3d7 (gpio: add flags argument to gpiod_get*() functions)
which appeared in v3.17-rc1, the gpiod_get* functions take an additional
parameter that allows to specify direction and initial value for output.
Moreover use devm_gpiod_get_optional instead of ignoring all errors
returned by devm_gpiod_get and simplify accordingly.

The result is more strict error handling which is good.

Oliver Hartkopp a5581ef4c2 can: introduce new raw socket option to join the given CAN filters
The CAN_RAW socket can set multiple CAN identifier specific filters that lead
to multiple filters in the af_can.c filter processing. These filters are
indenpendent from each other which leads to logical OR'ed filters when applied.

This socket option joines the given CAN filters in the way that only CAN frames
are passed to user space that matched *all* given CAN filters. The semantic for
the applied filters is therefore changed to a logical AND.

This is useful especially when the filterset is a combination of filters where
the CAN_INV_FILTER flag is set in order to notch single CAN IDs or CAN ID
ranges from the incoming traffic.

As the raw_rcv() function is executed from NET_RX softirq the introduced
variables are implemented as per-CPU variables to avoid extensive locking at
CAN frame reception time.

Oliver Hartkopp 514ac99c64 can: fix multiple delivery of a single CAN frame for overlapping CAN filters
The CAN_RAW socket can set multiple CAN identifier specific filters that lead
to multiple filters in the af_can.c filter processing. These filters are
indenpendent from each other which leads to logical OR'ed filters when applied.

This patch makes sure that every CAN frame which is filtered for a specific
socket is only delivered once to the user space. This is independent from the
number of matching CAN filters of this socket.

As the raw_rcv() function is executed from NET_RX softirq the introduced
variables are implemented as per-CPU variables to avoid extensive locking at
CAN frame reception time.

Nicolas Ferre c69618b3e4 net/macb: fix probe sequence to setup clocks earlier
As accessing the peripheral registers need the clocks to be set, we have to
enable them as soon as possible. Their configuration depend on the type of
device used and determined by the DT compatible string. That lead to add
another initialization function in the DT configuration structure.
As the device private structure length depend on an information read in the
registers, we have to store the clock pointers in temporary variables before
feeding the structure fields.

David S. Miller 7b6249bba9 Lots of updates for net-next; along with the usual flurry
of small fixes, cleanups and internal features we have:
  * VHT support for TDLS and IBSS (conditional on drivers though)
  * first TX performance improvements (the biggest will come later)
  * many suspend/resume (race) fixes
  * name_assign_type support from Tom Gundersen

Jiri Pirko fbcb217059 net: rename dev to orig_dev in deliver_ptype_list_skb
Unlike other places, this function uses name "dev" for what should be
"orig_dev", which might be a bit confusing. So fix this.

Eran Ben Elisha 6fcd27354b net/mlx4_en: Support general selective view of ethtool statistics
The driver uses a bitmask to indicate which statistics should be
displayed to the user in ethtool. The bitmask is u64, therefore we are
limited for a selective view of up to 64 statistics. Extend the bitmap
in order to show more than 64 statistics.

In addition, add packet statistics to the ethtool display for PF.
