b08e1ed9cf ixgbe: zero out mailbox buffer on init
This patch initializes the msgbuf array to 0 in order to avoid using random
numbers from the memory as MAC address for the VF.

  ixgbe: ethtool ixgbe_diag_test cleanup

Specifically forcing the laser before the link check can lead to
inconsistent results because it does not guarantee that the link will be
negotiated correctly. Such is the case when dual speed SFP+ module is
connected to a gigabit link partner.

bd8a1b1290 ixgbe: fix incorrect limit value in ring transverse
We were transversing the tx_ring with IXGBE_NUM_RX_QUEUES.  Now this define
happens to have the correct value but this is misleading and a change later
could easily make this no longer true.  I updated it to netdev->num_tx_queues
like we use in ixgbe_get_strings().

f4f1040ae6 ixgbe: disable link when adapter goes down
This patch fixes an issue with the 82599 adapter where it can potentially keep
link lights up when the adapter has gone down. The patch adds a function which
ensures link is disabled, and calls this function when the adapter transitions

80b17be70b qlcnic: underflow in qlcnic_validate_max_tx_rings()
This function checks the upper bound but it doesn't check for negative
numbers:

	if (txq > QLCNIC_MAX_TX_RINGS) {

I've solved this by making "txq" a u32 type.  I chose that because
->tx_count in the ethtool_channels struct is a __u32.

This bug was added in aa4a1f7df7 ('qlcnic: Enable Tx queue changes using

bea5098848 be2net: Fix be_cmd_if_create() to use MBOX if MCCQ is not created
Currently the IF_CREATE FW cmd is issued only *after* MCCQ is created as
it was coded to only use MCCQ. By fixing this, cmd_if_create() can be
called before MCCQ is created and the same routine for VF provisioning
can be called after.
This allows for consolidating all the queue create routines by moving
the be_cmd_if_create() call above all queue create calls in be_setup().

b766630b35 sfc: Eliminate struct efx_mtd
Currently we use struct efx_mtd to represent a physical NVRAM device
and struct efx_mtd_partition to represent a partition on that device.
But this only really makes sense for Falcon, as we don't know or care
whether MC-managed NVRAM partitions are on one or more physical
devices.  It complicates iteration and provides little benefit.
Therefore:

- Replace the pointer to efx_mtd in mtd_info::priv with a pointer to efx_nic
- Move the falcon_spi_device pointer into the union in struct efx_mtd_partition
- Move the device name to efx_mtd_partition::dev_type_name
- Move the efx_mtd_ops pointer to efx_nic::mtd_ops
- Make efx_nic::mtd_list a list of partitions

964e61355e sfc: Cleanup Falcon-arch simple MAC filter state
On Falcon we implement MAC filtering requested by the stack using the
MAC wrapper's single unicast filter and multicast hash filter.  Siena
is very similar, though MAC configuration is mediated by the MC.

Since MCDI operations may sleep, reconfiguration is deferred from
ndo_set_rx_mode to a work item.  However, it still updates the private
variables describing the filter state synchronously.  Contrary to
comments, the later use of these variables is not protected using the
address lock, resulting in race conditions.

Move the state update to a new function
efx_farch_filter_sync_rx_mode() and make the Falcon-arch MAC
configuration functions call that, so that its use is consistently
serialised by the mac_lock.

Invert and rename the promiscuous flag to the more accurate
unicast_filter, and comment that both this and multicast_hash are
not used on EF10.

8803e15042 sfc: Add flag for stack-owned RX MAC filters
MAC filters inserted on request from the stack (ndo_set_rx_mode)
should allow manual steering but not removal.  Currently we have a
special case for Siena's all-multicast and all-unicast MAC filters,
but on EF10 we need to allow for steering of precise MAC filters as
well.

The EFX_FILTER_FLAG_RX_STACK flag changes the behaviour of replacement
and removal requests:

- Replacement *of* a filter with this flag never clears the flag but
  does change steering and saved priority
- Replacement *by* a filter with this flag only sets the flag but does
  not change steering
- Removal with priority < EFX_FILTER_PRI_REQUIRED really resets RX
  steering and saved priority

This could support precise MAC filtering on Siena in future.

As a side-benefit, the default MAC filters are hidden from ethtool
until they are steered.

This patch attempts to work around a problem found with some systems where
the call to pci_diable_link_state_locked() fails.  As a result, ASPM is not,
in fact, disabled.  Changing disable ASPM code to check if state actually
is disabled after the call and, if not, try another way to disable it.

0cf04597b4 e1000e: cleanup whitespace in recent commit
Commit (c96ddb0b e1000e: Use marco instead of digit for defining
e1000_rx_desc_packet_split) moved a define from one file to another but
missed using proper indentation/whitespace.

ed12cc9a14 igb: Expose RSS indirection table for ethtool
This patch adds the ethtool callbacks necessary to change the RETA
indirection table from userspace.

In order to achieve this, we add the indirection table field (rss_indir_tbl)
in the board specific data structure (struct igb_adapter) to preserve the
values across hardware resets.

The indirection table must be initialized with default values in the
following cases:
	* at module init time
	* when the number of RX queues changes.
For this reason we add a new field (rss_indir_tbl_init) in igb_adapter
that keeps track of the number of RX queues. Whenever the number of RX
queues changes, the rss_indir_tbl is modified and initialized with default
values. The rss_indir_tbl_init is updated accordingly.
