we have two processes to do:
P1#: ifconfig eth0 down; which will call bnx2_close, then will
, and set Null to stats_blk
P2#: ifconfig eth0; which will call bnx2_get_stats64, it will
use stats_blk.
In one case:
--P1#-- --P2#--
stats_blk(no null)
bnx2_free_mem
->bp->stats_blk = NULL
GET_64BIT_NET_STATS
then it will cause 'NULL Pointer' Problem.
it is as well with 'ethtool -S ethx'.
Allocate the statistics block at probe time so that this problem is
impossible

t4_check_fw_version() can return several error codes (-EINVAL, -EBUSY,
-EAGAIN). The present code sets the adapter state to UNINIT only if its
an EFAULT. In all the error cases set the adapter to uninitialized state.
In t4_check_fw_version() if call to t4_get_fw_version() fails, repeat the
operation a few times before returning failure.

The Kconfig currently controlling compilation of this code is:
drivers/net/ethernet/ti/Kconfig:config TI_CPSW_PHY_SEL
drivers/net/ethernet/ti/Kconfig: bool "TI CPSW Switch Phy sel Support"
...meaning that it currently is not being built as a module by anyone.
Lets remove the couple traces of modularity so that when reading the
driver there is no doubt it is builtin-only.
Since module_platform_driver() uses the same init level priority as
builtin_platform_driver() the init ordering remains unchanged with
this commit.
Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.
We also delete the MODULE_LICENSE tag etc. since all that information
was (or is now) contained at the top of the file in the comments.

In preparation to handling system errors at the mlx5_core level, change the
interface of cmd_work_handler to accept a 64 bit argument for the vector.
This allows to encode a flag that signifies when the handler is called
as a result of a driver logic that wishes to terminate commands that
the hardware may not be able to terminate. Such command completions
are detected at the handler and proper return status is encoded.
To be able to terminate page handler commands, we make sure to set
the corresponding bit in the bitmask.

Using VFGEN_RSTAT to detect a VF reset is an endeavor that is fraught
with peril. It's entirely too easy to miss a reset because none of the
bits are sticky. By the time the VF driver reads the register, the reset
may have been processed and cleaned up by the PF driver, leaving the
register in the same state that it was before the reset.
Instead, detect a reset with the VF_ARQLEN register. When the VF is
reset, the enable bit in this register is cleared, and it stays cleared
until the VF driver processes the reset and re-enables the admin queue.
Because we now deal with multiple registers in the reset and watchdog
tasks, rename the rstat_val variable to reg_val.

Ran into an issue where PF's VSI type list was different from VF's,
which was resulted in different enum index. The VSI type list can
be different depending on what build flag is used for PF and VF.
The change is to explicitly assign enum index for each VSI type
so that PF and VF always reference to the same VSI type event if the
enum lists are different.

This patch fixes a problem where the PF's fdir filter table would have an
entry that the hw was unable to add. This notification happens in the hot
path, so instead of trying to fix it then, we note the location in the
failure case and delete it during regular fdir subtask callback. Without
this patch, a case can occur where an invalid entry gets replayed and a
valid one is not.

Under certain circumstances, the device may not have enough resources to
enable all of the VFs that it advertises in config space. Although the
number of supported VFs is reported upon driver init, it is not obvious
when this is different from the number reported in config space. To
eliminate this confusion, add an error message explaining the problem.
Additionally, move the 'Allocating VFs' message down below the error
checks so as to prevent further confusion.

====================
Intel Wired LAN Driver Updates 2015-10-07
This series contains updates to i40e and i40evf only.
Paul updates i40e to simply increase the amount of time we wait for a
reset to complete since we have seen in some rare occasions the reset
can take longer to complete.
Shannon updates the driver to turn on Wake-on-LAN by default if it is
enabled in the hardware config to begin with, rather than always disable
it and wait for the user to expressly turn it on. Added new device id's
and support for future devices. Fixed a possible type compare problem
between a size and possible negative number. Also fixed a shift value
that was wrong, which ended up with a bad bitmask. Did general house
cleaning of the driver to cleanup several low lying fruit in the
driver. Fixed an issue where new unicast address's would be added to
the VSI list and then immediately removed and would never actually
make it down to the hardware. Resolved the issue by removing the
separation from unicast and multicast in the search for filters to be
deleted.
Mitch fixes an issue where the hardware would continue to access the
memory formerly used by the rings for a VF which have been removed,
causing memory corruption or DMAR errors. To relieve this condition,
explicitly stop all rings associated with each VF before releasing its
resources. Also fixed a panic if the driver is unable to enable MSI-X
or its unable to acquire enough vectors, so propagate interrupt
allocation failure information to the calling function. Cleaned up
opcode that is not required.
Carolyn extends the size of the test available for the interrupt names
so that all the descriptive data available for the Flow Director
interrupts is not truncated.
Catherine fixes an issue where there was a possibility of speed getting
set to 0 if advertised is set to 0 (which is the case when autoneg is
disabled).
Jesse fixes the checksum on big endian machines, so added code to swap
it correctly. Also fixed a bug in the return from get_link_status()
where only true or false was being returned, but false could mean
multiple things. So allow the caller to get all the return values
in the call chain bubbled back to the source so that the reason for
the failure does not get lost.
Anjali adds statistics to keep track of how many times we ask the stack
to linearize the SKB because the hardware cannot handle SKBs with more
than 8 frags per segment/single packet.
