      {NET, IB}/mlx4: Add device managed flow steering firmware API · 0ff1fb65
      由 Hadar Hen Zion 提交于 
      The driver is modified to support three operation modes.

If supported by firmware use the device managed flow steering
API, that which we call device managed steering mode. Else, if
the firmware supports the B0 steering mode use it, and finally,
if none of the above, use the A0 steering mode.

When the steering mode is device managed, the code is modified
such that L2 based rules set by the mlx4_en driver for Ethernet
unicast and multicast, and the IB stack multicast attach calls
done through the mlx4_ib driver are all routed to use the device
managed API.

When attaching rule using device managed flow steering API,
the firmware returns a 64 bit registration id, which is to be
provided during detach.

Currently the firmware is always programmed during HCA initialization
to use standard L2 hashing. Future work should be done to allow
configuring the flow-steering hash function with common, non
proprietary means.

      net/mlx4_core: Add firmware commands to support device managed flow steering · 8fcfb4db
      由 Hadar Hen Zion 提交于 
      Add support for firmware commands to attach/detach a new device managed
steering mode. Such network steering rules allow the user to provide an
L2/L3/L4 flow specification to the firmware and have the device to steer
traffic that matches that specification to the provided QP.

      net/mlx4: Set steering mode according to device capabilities · c96d97f4
      由 Hadar Hen Zion 提交于 
      Instead of checking the firmware supported steering mode in various
places in the code, add a dedicated field in the mlx4 device capabilities
structure which is written once during the initialization flow and read
across the code.

This also set the grounds for add new steering modes. Currently two modes
are supported, and are named after the ConnectX HW versions A0 and B0.

A0 steering uses mac_index, vlan_index and priority to steer traffic
into pre-defined range of QPs.

B0 steering uses Ethernet L2 hashing rules and is enabled only
if the firmware supports both unicast and multicast B0 steering,

The current steering modes are relevant for Ethernet traffic only,
such that Infiniband steering remains untouched.

      phy: add the EEE support and the way to access to the MMD registers. · a59a4d19
      由 Giuseppe CAVALLARO 提交于 
      This patch adds the support for the Energy-Efficient Ethernet (EEE)
to the Physical Abstraction Layer.
To support the EEE we have to access to the MMD registers 3.20 and
7.60/61. So two new functions have been added to read/write the MMD
registers (clause 45).

An Ethernet driver (I tested the stmmac) can invoke the phy_init_eee to properly
check if the EEE is supported by the PHYs and it can also set the clock
stop enable bit in the 3.0 register.
The phy_get_eee_err can be used for reporting the number of time where
the PHY failed to complete its normal wake sequence.

In the end, this patch also adds the EEE ethtool support implementing:
 o phy_ethtool_set_eee
 o phy_ethtool_get_eee

v1: initial patch
v2: fixed some errors especially on naming convention
v3: renamed again the mmd read/write functions thank to Ben's feedback
v4: moved file to phy.c and added the ethtool support.
v5: fixed phy_adv_to_eee, phy_eee_to_supported, phy_eee_to_adv return
    values according to ethtool API (thanks to Ben's feedback).
    Renamed some macros to avoid too long names.
v6: fixed kernel-doc comments to be properly parsed.
    Fixed the phy_init_eee function: we need to check which link mode
    was autonegotiated and then the corresponding bits in 7.60 and 7.61
    registers.
v7: reviewed the way to get the negotiated settings.
v8: fixed a problem in the phy_init_eee return value erroneously added
    when included the phy_read_status call.
v9: do not remove the MDIO_AN_EEE_ADV_100TX and MDIO_AN_EEE_ADV_1000T
    and fixed the eee_{cap,lp,adv} declaration as "int" instead of u16.

      Fix kernel-doc warning.  This struct member was removed in commit
87568264 ("irq: Remove irq_chip->release()") so remove its
associated kernel-doc entry also.
