These functions purpose is to add a new MAC filter correctly, whether
we're using VLANs or not. Their goal is to ensure that all active VLANs
get the new MAC filter. Rename them so that their intent is clear. They
function correctly regardless of whether we have any active VLANs or
only have I40E_VLAN_ANY filters. The new names convey how they function
in a more clear manner.

This function won't be appreciably slower when in VLAN mode, so there is
no real reason to not just call it directly. In either case, we still
must search the full table for a MAC/VLAN pair. We do get to stop
searching a tiny bit early in the case of knowing we are not in VLAN
mode, but this is a minor savings and we can avoid the code complexity
by not having to worry about the check.

Now that we have the separate i40e_(add|rm)_vlan_all_mac functions, we
should not be using the i40e_vsi_kill_vlan or i40e_vsi_add_vlan
functions when PVID is set or when VID is less than 1. This allows us to
remove some checks in i40e_vsi_add_vlan and ensures that callers which
need to handle VID=0 or VID=-1 don't accidentally invoke the VLAN mode
handling used to convert filters when entering VLAN mode. We also update
the functions to take u16 instead of s16 as well since they no longer
expect to be called with VID=I40E_VLAN_ANY.

The network stack no longer uses the last_rx member of struct net_device
since the bonding driver switched to use its own private last_rx in
commit 9f242738 ("bonding: use last_arp_rx in slave_last_rx()").

However, some drivers still (ab)use the field for their own purposes and
some driver just update it without actually using it.

Previously, there was an accompanying comment for the last_rx member
added in commit 4dc89133 ("net: add a comment on netdev->last_rx")
which asked drivers not to update is, unless really needed. However,
this commend was removed in commit f8ff080d ("bonding: remove
useless updating of slave->dev->last_rx"), so some drivers added later
on still did update last_rx.

Remove all usage of last_rx and switch three drivers (sky2, atp and
smc91c92_cs) which actually read and write it to use their own private
copy in netdev_priv.

Compile-tested with allyesconfig and allmodconfig on x86 and arm.

This patch does two things.

First it goes through and renames the __page_frag prefixed functions to
__page_frag_cache so that we can be clear that we are draining or
refilling the cache, not the frags themselves.

Second we drop the order parameter from __page_frag_cache_drain since we
don't actually need to pass it since all fragments are either order 0 or
must be a compound page.

Multiple IES API resets can cause a race condition where the mailbox
interrupt request bits can be cleared before being handled. This can
leave certain mailbox messages from the PF to be untreated and the PF
will enter in some inactive state. If this situation occurs, the IES API
will initiate a mailbox version reset which, then, trigger a mailbox
state change. Once this mailbox transition occurs (from OPEN to CONNECT
state), a request for reset will be returned.

This ensures that PF will undergo a reset whenever IES API encounters an
unknown global mailbox interrupt event or whenever the IES API
terminates.

Whenever the igb driver detects the result of a read operation returns
a value composed only by F's (like 0xFFFFFFFF), it will detach the
net_device, clear the hw_addr pointer and warn to the user that adapter's
link is lost - those steps happen on igb_rd32().

In case a PCI error happens on Power architecture, there's a recovery
mechanism called EEH, that will reset the PCI slot and call driver's
handlers to reset the adapter and network functionality as well.

We observed that once hw_addr is NULL after the error is detected on
igb_rd32(), it's never assigned back, so in the process of resetting
the network functionality we got a NULL pointer dereference in both
igb_configure_tx_ring() and igb_configure_rx_ring(). In order to avoid
such bug, this patch re-assigns the hw_addr value in the slot_reset
handler.

Several people have reported firmware leaving the I210/I211 PHY's page

causes the first accesses, PHY_IDx register reads, to access something
else, resulting in device probe failure:

    igb: Copyright (c) 2007-2014 Intel Corporation.
    igb: probe of 0000:01:00.0 failed with error -2

This problem began for them after a previous patch I submitted was

I210 devices using this firmware:

    Intel(R) Boot Agent GE v1.5.78
    Copyright (C) 1997-2014, Intel Corporation

Resetting the PHY before reading from it, ensures the page select
register is in its default state and doesn't make assumptions about
the PHY's register set before the PHY has been probed.

During systemd reboot sequence network driver interface is shutdown
by e1000_close. The PCI driver interface is shut by e1000_shutdown.
The e1000_shutdown checks for netif_running status, if still up it
brings down driver. But it disables msi outside of this if statement,
regardless of netif status. All this is OK when e1000_close happens
after shutdown. However, by default, everything in systemd is done
in parallel. This creates a conditions where e1000_shutdown is called

There are two problems with EEPROM access. One is that it needs to
hold the semaphore until the entire response is read or else the
response can be corrupted by other firmware accesses. The second
problem is that acquiring and releasing the semaphore is slow, so
it should be taken and released once when multiple EEPROM accesses
will be done.

Both of these issues can be solved by adding a new function,

Previously it was possible to trigger BUG_ON() check in free_msix_irqs()
in the case where we call ixgbevf_remove() after a failed recovery from
AER error because the interrupts were not freed.

Also moved the down and free functions into ixgbevf_close_suspend()
same as with ixgbe.
