    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
information. Since VFs don't initialize slowpath information, a VF reaching
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).

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.

In preparation for allowing PHY drivers to potentially override their
auto-negotiation done callback, move the contents of phy_aneg_done() to
genphy_aneg_done() since that function really is the generic
implementation based on the BMSR_ANEGCOMPLETE status.

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.

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.

Stick the label inside the same #ifdef that the code which calls

ARCH_HAS_IOREMAP_WC, such as arm, mips, sparc, ..., as the others
enable the write combining code and hence use the label.
