718f4a2537 be2net: Fix number of Rx queues used for flow hashing
Number of Rx queues used for flow hashing returned by the driver is
incorrect and this bug prevents user to use the last Rx queue in
indirection table.

Let's say we have a NIC with 6 combined queues:

[root@sm-03 ~]# ethtool -l enp4s0f0
Channel parameters for enp4s0f0:
Pre-set maximums:
RX:             5
TX:             5
Other:          0
Combined:       6
Current hardware settings:
RX:             0
TX:             0
Other:          0
Combined:       6

Default indirection table maps all (6) queues equally but the driver
reports only 5 rings available.

[root@sm-03 ~]# ethtool -x enp4s0f0
RX flow hash indirection table for enp4s0f0 with 5 RX ring(s):
    0:      0     1     2     3     4     5     0     1
    8:      2     3     4     5     0     1     2     3
   16:      4     5     0     1     2     3     4     5
   24:      0     1     2     3     4     5     0     1
...

Now change indirection table somehow:

[root@sm-03 ~]# ethtool -X enp4s0f0 weight 1 1
[root@sm-03 ~]# ethtool -x enp4s0f0
RX flow hash indirection table for enp4s0f0 with 6 RX ring(s):
    0:      0     0     0     0     0     0     0     0
...
   64:      1     1     1     1     1     1     1     1
...

Now it is not possible to change mapping back to equal (default) state:

[root@sm-03 ~]# ethtool -X enp4s0f0 equal 6
Cannot set RX flow hash configuration: Invalid argument

710f3e5961 be2net: Support UE recovery in BEx/Skyhawk adapters
This patch supports recovery from UEs caused due to Transient Parity
Errors (TPE), in BE2, BE3 and Skyhawk adapters. This change avoids
system reboot when such errors occur. The driver recovers from these
errors such that the adapter resumes full operational status as prior
to the UE.

Following is the list of changes in the driver to support this:

o The driver registers its UE recoverable capability with ARM FW at init
time. This also allows the driver to know if the feature is supported in
the FW.

o As the UE recovery requires precise time bound processing, the driver
creates its own error recovery work queue with a single worker thread (per
module, shared across functions).

o Each function runs an error detection task at an interval of 1 second as
required by the FW. The error detection logic already exists for BEx/SH,
but it now runs in the context of a separate worker thread.

o When an error is detected by the task, if it is recoverable, the PF0
driver instance initiates a soft reset, while other PF driver instances
wait for the reset to complete and the chip to become ready. Once
the chip is ready, all driver instances including PF0, resume to
reinitialize the respective functions.

o The PF0 driver checks for some recovery criteria, to determine if the
recovery can be initiated. If the criteria is not met, the PF0 driver does
not initiate a soft reset, it retains the existing behavior to stop
further processing and requires a reboot to get the chip to operational
state again.

o To allow each function to share the workq, while also making progress in
its recovery process, a per-function recovery state machine is used.
The per-function tasks avoid blocking operations like msleep() while in
this state machine (until reinit state) and instead reschedule for the
required delay.

o With these changes, the existing error recovery code for Lancer also
runs in the context of the new worker thread.

following cmds:
ethtool -L ethX combined N rx M-N  (when N < M)
ethtool -L ethX combined M tx N-M (when M < N)

Setting both RX-only and TX-only channels is still not supported.

45f13df75f be2net: Enable Wake-On-LAN from shutdown for Skyhawk
Skyhawk does support wake-up from ACPI shutdown state - S5, provided the
platform supports it (like Auxiliary power source etc). The changes listed
below are done to fix this.

1) There's no need to defer the HW configuration of WOL to be_suspend().
Remove this in be_suspend() and move it to be_set_wol() ethtool function
so it is configured directly in the context of ethtool. This automatically
takes care of the shutdown case.

2) The driver incorrectly uses WOL_CAP field in the FW response to
get_acpi_wol_cap() command, to determine if WOL is enabled. Instead the
driver must rely on the macaddr field in the response to infer WOL state.

3) In be_get_config() during init, if we find that WOL is enabled in FW,
call pci_enable_wake() to enable pmcsr.pme_en bit. This is needed to
support persistent WOL configuration provided by the FW in some platforms.

4) Remove code in be_set_wol() that writes to PCICFG_PM_CONTROL_OFFSET
to set pme_en bit; pci_enable_wake() sets that.

5f07b3c51a be2net: support TX batching using skb->xmit_more flag
This patch uses skb->xmit_more flag to batch TX requests.
TX is flushed either when xmit_more is false or there is
no more space in the TXQ.

Skyhawk-R and BEx chips require an even number of wrbs to be posted.
So, when a batch of TX requests is accumulated, the last header wrb
may need to be fixed with an extra dummy wrb.

This patch refactors be_xmit() routine as a sequence of be_xmit_enqueue()
and be_xmit_flush() calls. The Tx completion code is also
updated to be able to unmap/free a batch of skbs rather than a single
skb.

892311f66f ethtool: Support for configurable RSS hash function
This patch extends the set/get_rxfh ethtool-options for getting or
setting the RSS hash function.

It modifies drivers implementation of set/get_rxfh accordingly.

This change also delegates the responsibility of checking whether a
modification to a certain RX flow hash parameter is supported to the
driver implementation of set_rxfh.

User-kernel API is done through the new hfunc bitmask field in the
ethtool_rxfh struct. A bit set in the hfunc field is corresponding to an
index in the new string-set ETH_SS_RSS_HASH_FUNCS.

Got approval from most of the relevant driver maintainers that their
driver is using Toeplitz, and for the few that didn't answered, also
assumed it is Toeplitz.

This patch fixes the following minor issues with log messages in be2net:
  1) Period is not required at the end of log message.
  2) Remove "Unknown grp5 event" logs to reduce noise. The driver can safely
     ignore async events from FW it's not interested in.
  3) Reword a log message for better readability to say that SRIOV
     "is disabled" rather than "not supported".

ethtool expects a -ve status value to be returned when a driver method
