71839f7d16 sfc: Distinguish critical and non-critical over-temperature conditions
Set both the 'maximum' and critical temperature limits for LM87
hardware monitors on Falcon boards.  Do not shut down a port until the
critical temperature is reached, but warn as soon as the 'maximum'
temperature is reached.

f18ca36461 sfc: Reduce log level for MCDI error response in efx_mcdi_rpc()
Some errors are expected, e.g. when sending new commands to an MC
running old firmware.  Only the caller of efx_mcdi_rpc() can decide
what is a real error.  Therefore log the error responses with
netif_dbg().

0793f83f0e bnx2x: Add Nic partitioning mode (57712 devices)
NIC partitioning is another flavor of multi function - having few
PCI functions share the same physical port. Unlike the currently
supported mode of multi-function which depends on the switch
configuration and uses outer-VLAN, the NPAR mode is switch independent
and uses the MAC addresses to distribute incoming packets to the different
functions. This patch adds the specific HW setting of the NPAR mode
and some distinctions between switch dependent (SD) and
switch independent (SI) multi-function (MF) modes where the configuration
is not the same.

Advance driver version to 1.60.00-6

6a632625c7 ethoc: remove division from loops
Calculating the BD entry using a modulus operation isn't optimal, especially
inside the loop.  This patch removes the modulus operations in favour of:

i)  simply checking for wrapping in the case of cur_rx
ii) forcing num_tx to be a power of two and using it to mask out the
    entry from cur_tx

The also prevents possible issues related overflow of the cur_rx and cur_tx
counters.

8dac428ae9 ethoc: rework mdio read/write
MDIO read and write were checking whether a timeout had expired to determine
whether to recheck the result of the MDIO operation.  Under heavy CPU usage,
however, it was possible for the timeout to expire before the routine got
around to be able to check a second time even, thus erroneousy returning an
-EBUSY.

This patch changes the the MDIO IO routines to try up to five times to complete
the operation before giving up, thus lessening the dependency on CPU load.

This resolves a problem whereby a ping flood would keep the CPU so busy that
the above problem would manifest itself; the MDIO command to check link status
would fail and the interface would erroneously be shut down.

fa98eb0e86 ethoc: rework interrupt handling
The old interrupt handling was incorrect in that it did not account for the
fact that the interrupt source bits get set irregardless of whether or not
their corresponding mask is set.  This patch fixes that by masking off the
source bits for masked interrupts.

Furthermore, the handling of transmission events is moved to the NAPI polling
handler alongside the reception handler, thus preventing a whole bunch of
interrupts during heavy traffic.

Driver maintains a count of number of pci functions probed
