bnx2x: Enhancements & semantic changes series

This patch series contains several semantic (or mostly semantic) patches,
as well as adding support for packet aggregations on the receive path
of windows VMs and updating bnx2x to the new FW recently accepted upstream.

Please consider applying these patches to `net-next'.

(This is a repost as net-next was still closed when this was previously
sent)

    This new firmware fixes following bugs:
     1. HW attention appears and traffic stops when iSCSI firmware tries to
        retransmit iSCSI login command when the iSCSI login is carrying data
        not aligned to 4-bytes.
     2. FCoE traffic fails to run when running in switch-independent multi-function
        mode and there's more than one interface supporting FCoE on a given port.
     3. While two ports are running FCoE with at least one of them has a function
        number (>1) on the same engine in a 4-port device a zeroed CQE is given,
        causing FCoE traffic to stop.

bnx2x_panic_dump() prints all kind of driver information, including slowpath

this flow will likely cause a panic in the system as it will access NULL

There are several places in IOV related flows where PF needs to determine
whether a VF slowpath elements have already been configured (i.e., this
affect its ability to configure/remove classifications for the VF).

This patch changes the conditions for the validation and performs a cleaner
validation (e.g., by replacing several validations with a single one).

of_get_phy_mode() uses a local array to map phy_interface_t values from
include/linux/net/phy.h to a string which is read from the 'phy-mode' or
'phy-connection-type' property. In preparation for exposing the PHY
interface mode through sysfs, perform the following:

- mode phy_modes from drivers/of/of_net.c to include/linux/phy.h such
  that it is right below the phy_interface_t enum
- make it a static inline function returning the string such that we can
  use it by just including include/linux/net/phy.h
- add a PHY_INTERFACE_MODE_MAX enum value to guard the iteration in
  of_get_phy_mode()

Some PHYs out there can be very quirky with respect to how they would
report the auto-negotiation is completed. Allow drivers to override the
generic aneg_done() implementation by providing their own.

Since not all drivers have been updated yet to use genphy_aneg_done() as
aneg_done() callback, we explicitely check that this callback is valid
before calling into it.

phy_print_status() currently uses dev_name(&phydev->dev) which will
usually result in printing something along those lines for Device Tree
aware drivers:

libphy: f0b60000.etherne:0a - Link is Down
libphy: f0ba0000.etherne:00 - Link is Up - 1000/Full

This is not terribly useful for network administrators or users since we
expect a network interface name to be able to correlate link events with
interfaces. Update phy_print_status() to use netdev_info() with
phydev->attached_dev which is the backing network device for our PHY
device. The leading dash is removed since netdev_info() prefixes the
messages with "<interface>: " already.

Cleanup patches for the SFC driver

This patch set consists of some cleanup and housekeeping
patches for the sfc driver.
These patches help to reduce the differences between the in-
tree and out-of-tree driver.

  sfc: Rewrite adjustment of PPS event in a clearer way
  sfc: Replace TSOH_OFFSET with the equivalent NET_IP_ALIGN
  sfc: Rename 'use_options' variable in tso_start() to clearer
    'use_opt_desc'
  sfc: Remove unused definitions of EF10 user-mode DMA descriptors
  sfc: Correct comment about number of TX queues used on EF10
  sfc: Preserve rx_frm_trunc counters when resizing DMA rings
  sfc: Use canonical pointer type for MAC address in
    efx_set_mac_address()
  sfc: Update product naming
  sfc: Cosmetic changes to self-test from the out-of-tree driver
  sfc: Fail self-test with -EBUSY, not -EIO, if the device is busy
  sfc: Add/remove blank lines to taste

There is substantial latency in generation and handling of PPS events
from the NIC, which we have to correct for before passing a host
timestamp to the PPS subsystem.  We compare clocks with the MC,
giving us two offsets to subtract from the timestamp generated by
pps_get_ts():

(a) Time from the last good sync (where we got host and NIC timestamps
    for nearly the same instant) to the time we called pps_get_ts()
(b) Time from NIC top of second to the last good sync

We currently calculate (a) + (b) in a quite confusing way.
Instead, calculate (a) completely, then add (b) to it.
