====================
sh_eth: E-MAC interrupt handler cleanups

   Here's a set of 3 patches against DaveM's 'net-next.git' repo. I'm cleaning
up the E-MAC interrupt handling with the main goal of factoring out the E-MAC
interrupt handler into a separate function.

[1/3] sh_eth: handle only enabled E-MAC interrupts
[2/3] sh_eth: no need for *else* after *goto*
[3/3] sh_eth: factor out sh_eth_emac_interrupt()

9b39f05ce8 sh_eth: factor out sh_eth_emac_interrupt()
The E-MAC interrupt (EESR.ECI) is not always caused  by an error condition,
so  it really shouldn't be handled by sh_eth_error(). Factor out the E-MAC
interrupt handler, sh_eth_emac_interrupt(),  removing the ECI bit from the
EESR's values throughout the driver...

Update Cogent Embedded's copyright and clean up the whitespace in Renesas'
copyright, while at it...

1940f24076 sh_eth: no need for *else* after *goto*
Well, checkpatch.pl complains about *else* after *return* and *break* but
not after *goto*... and it probably should have complained about the code
in sh_eth_error().  Win couple LoCs by removing that *else*. :-)

4063469971 sh_eth: handle only enabled E-MAC interrupts
The driver should only handle the enabled E-MAC interrupts, like it does
for the E-DMAC interrupts since commit 3893b27345 ("sh_eth: workaround
for spurious ECI interrupt"),  so mask ECSR with  ECSIPR when reading it
in sh_eth_error().

====================
net: systemport: Fix padding vs. TSB insertion

This patch series fixes how we pad the packets submitted to the SYSTEMPORT
adapter, and how the transmit status block (prepended 8 bytes) fits in the
picture. The first patch is not technically a bug fix, but is required for the
second path to be applied and to greatly simplify the skb length calculation.

38e5a85562 net: systemport: Pad packet before inserting TSB
Inserting the TSB means adding an extra 8 bytes in front the of packet
that is going to be used as metadata information by the TDMA engine, but
stripped off, so it does not really help with the packet padding.

For some odd packet sizes that fall below the 60 bytes payload (e.g: ARP)
we can end-up padding them after the TSB insertion, thus making them 64
bytes, but with the TDMA stripping off the first 8 bytes, they could
still be smaller than 64 bytes which is required to ingress the switch.

Fix this by swapping the padding and TSB insertion, guaranteeing that
the packets have the right sizes.

IPvlan setup uses one mac-address (of master). The IPv6 link-local
addresses are derived using the mac-address on the link. Lack of
dev-ids makes these link-local addresses same for all slaves including
that of master device. dev-ids are necessary to add differentiation

a1b7a4dea6 xfs: fix crash and data corruption due to removal of busy COW extents
There is a race window between write_cache_pages calling
clear_page_dirty_for_io and XFS calling set_page_writeback, in which
the mapping for an inode is tagged neither as dirty, nor as writeback.

If the COW shrinker hits in exactly that window we'll remove the delayed
COW extents and writepages trying to write it back, which in release
kernels will manifest as corruption of the bmap btree, and in debug
kernels will trip the ASSERT about now calling xfs_bmapi_write with the
COWFORK flag for holes.  A complex customer load manages to hit this
window fairly reliably, probably by always having COW writeback in flight
while the cow shrinker runs.

This patch adds another check for having the I_DIRTY_PAGES flag set,
which is still set during this race window.  While this fixes the problem
I'm still not overly happy about the way the COW shrinker works as it
still seems a bit fragile.

10GbE Intel Wired LAN Driver Updates 2017-01-03

This series contains updates to ixgbe and ixgbevf only.

Emil fixes ixgbe to use the NVM settings for FEC, so do not override the
settings.  Fixed the indirection table for x550, where newer devices can
support up to 64 RSS queues.  Extends the rtnl_lock() to protect the call
to netif_device_detach() and ixgbe_clear_interrupt_scheme() to avoid
against a double free WARN and/or a BUG in free_msi_irqs().  Fixed AER
error handling by making sure that the driver frees the IRQs in
ixgbe_io_error_detected() when responding to a PCIe AER error, and to
restore them when the interface recovers.

Tony updates the driver to report the driver version to the firmware using
the host interface command for x550 devices.  Fixed the PHY reset check
for x550em_ext_t PHY type.  Fixed bounds checking for x540 devices to
ensure the index is valid for the LED function.  Fixed the BaseT adapters
which support 100Mb capability and were not reporting the capability.

Ken Cox adds a missing check for the trusted bit before trying to set the
MACVLAN MAC address.

Yusuke Suzuki fixes an issue with 82599 and x540 devices where receive
timestamps were not working becase the bitwise operation for RX_HWSTAMP
falg was incorrect.

Don ensures that x553 KR/KX devices correctly advertise link speeds.
Adds the mailbox message to allow for VF promiscuous mode support.

Mark fixes two issues with EEPROM access, where the semaphore was not
being held until the entire response was read and the acquiring/releasing
of the semaphore is slow.  Cleaned up firmware version method and
functions which are no longer used.  Added new interfaces for firmware
commands to access some new PHYs.

v2: fixed tab indentation in patch 12 and mis-spelled words in patch 15
    based on feedback from Sergei Shtylyov and Rami Rosen.

3efa9ed260 ixgbe: Fix issues with EEPROM access
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,
ixgbe_hic_unlocked, to issue firmware commands that will assume
that the caller has acquired the needed semaphore.

aeb4c73100 ixgbe: Fix incorrect bitwise operations of PTP Rx timestamp flags
Rx timestamp does not work on 82599 and X540 because bitwise operation
of RX_HWTSTAMP flags is incorrect and ixgbe_ptp_rx_hwtstamp() is never

b19cf6eea9 ixgbevf: fix AER error handling
Make sure that we free the IRQs in ixgbevf_io_error_detected() when
responding to an PCIe AER error and also restore them when the
interface recovers from it.

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.

a9d2d53a78 ixgbe: test for trust in macvlan adjustments for VF
There are two methods for setting mac addresses in a Macvlan, that
differentiate themselves in the function macvlan_set_mac_Address.
If the macvlan mode is passthru, then we use the dev_set_mac_address
method, otherwise we use the dev_uc api via macvlan_sync_addresses.
The latter method (which would stem from using any non-passthru mode,
like bridge, or vepa), calls down into the driver in a path that terminates
in ixgbevf_set_uc_addr_vf, which sends a IXGBE_VF_SET_MACVLAN message,
which causes the pf to spawn the noted error message.  This occurs because
it appears that the guest is trying to delete the mac address of the macvlan
before adding another.

The other path in macvlan_set_mac_address uses dev_set_mac_address, which
calls into ixgbevf_set_mac which uses the IXGBE_VF_SET_MAC_ADDR to the
pf to set the macvlan mac address.

The discrepancy here is in the handlers.  The handler function for
IXGBE_VF_SET_MAC_ADDR (ixgbe_set_vf_mac_addr) has a check for
the vfinfo[].trusted bit to allow the operation if the vf is trusted.
In comparison, the IXGBE_VF_SET_MACVLAN message handler
(ixgbe_set_vf_macvlan_msg) has no such check of the trusted bit.

2dad7b2775 ixgbevf: handle race between close and suspend on shutdown
When an interface is part of a namespace it is possible that
ixgbevf_close() may be called while ixgbevf_suspend() is running
which ends up in a double free WARN and/or a BUG in free_msi_irqs()

To handle this situation we extend the rtnl_lock() to protect the
call to netif_device_detach() and check for !netif_device_present()
to avoid entering close while in suspend.

Also added rtnl locks to ixgbevf_queue_reset_subtask().
