====================
Intel Wired LAN Driver Fixes 2019-03-26

This series contains updates to igb, ixgbe, i40e and fm10k.

Jake fixes an issue with PTP in i40e where a previous commit resulted
in a regression where the driver would interpret small negative
adjustments as large positive additions, resulting in incorrect
behavior.

Arvind Sankar fixes an issue in igb where a previous commit would cause
a warning in the PCI pm core and resulted in pci_pm_runtime_suspend
would not call pci_save_state or pci_finish_runtime_suspend.

Ivan Vecera fixes MDIO bus registration with ixgbe, where the driver was
ignoring errors returned when registering and would leave the pointer in
a NULL state which triggered a BUG when un-registering.

Stefan Assmann fixes the check for Wake-On-LAN for i40e, which only
supports magic packet.

Yue Haibing fixes a potential NULL pointer de-reference in fm10k by
adding a simple check if the value is NULL.

      vrf: prevent adding upper devices · 1017e098
      Sabrina Dubroca authored 
      VRF devices don't work with upper devices. Currently, it's possible to
add a VRF device to a bridge or team, and to create macvlan, macsec, or
ipvlan devices on top of a VRF (bond and vlan are prevented respectively
by the lack of an ndo_set_mac_address op and the NETIF_F_VLAN_CHALLENGED
feature flag).

Fix this by setting the IFF_NO_RX_HANDLER flag (introduced in commit
f5426250 ("net: introduce IFF_NO_RX_HANDLER")).

      thunderx: eliminate extra calls to put_page() for pages held for recycling · cd35ef91
      Dean Nelson authored 
      For the non-XDP case, commit 77322538 ("net: thunderx: Optimize
page recycling for XDP") added code to nicvf_free_rbdr() that, when releasing
the additional receive buffer page reference held for recycling, repeatedly
calls put_page() until the page's _refcount goes to zero. Which results in
the page being freed.

This is not okay if the page's _refcount was greater than 1 (in the non-XDP
case), because nicvf_free_rbdr() should not be subtracting more than what
nicvf_alloc_page() had previously added to the page's _refcount, which was
only 1 (in the non-XDP case).

This can arise if a received packet is still being processed and the receive
buffer (i.e., skb->head) has not yet been freed via skb_free_head() when
nicvf_free_rbdr() is spinning through the aforementioned put_page() loop.

If this should occur, when the received packet finishes processing and
skb_free_head() is called, various problems can ensue. Exactly what, depends on
whether the page has already been reallocated or not, anything from "BUG: Bad
page state ... ", to "Unable to handle kernel NULL pointer dereference ..." or
"Unable to handle kernel paging request...".

So this patch changes nicvf_free_rbdr() to only call put_page() once for pages
held for recycling (in the non-XDP case).

      Commit 77322538 ("net: thunderx: Optimize page recycling for XDP")
added code to nicvf_alloc_page() that inadvertently disables receive buffer
page recycling for the non-XDP case by always NULL'ng the page pointer.

This patch corrects two if-conditionals to allow for the recycling of non-XDP
mode pages by only setting the page pointer to NULL when the page is not ready
for recycling.

      Christoph reported a stall while peeking datagram with an offset when
busy polling is enabled. __skb_try_recv_datagram() uses as the loop
termination condition 'queue empty'. When peeking, the socket
queue can be not empty, even when no additional packets are received.

Address the issue explicitly checking for receive queue changes,
as currently done by __skb_wait_for_more_packets().

      net: dsa: mv88e6xxx: fix few issues in mv88e6390x_port_set_cmode · 5ceaeb99
      Heiner Kallweit authored 
      This patches fixes few issues in mv88e6390x_port_set_cmode().

1. When entering the function the old cmode may be 0, in this case
   mv88e6390x_serdes_get_lane() returns -ENODEV. As result we bail
   out and have no chance to set a new mode. Therefore deal properly
   with -ENODEV.

2. Once we have disabled power and irq, let's set the cached cmode to 0.
   This reflects the actual status and is cleaner if we bail out with an
   error in the following function calls.

3. The cached cmode is used by mv88e6390x_serdes_get_lane(),
   mv88e6390_serdes_power_lane() and mv88e6390_serdes_irq_enable().
   Currently we set the cached mode to the new one at the very end of
   the function only, means until then we use the old one what may be
   wrong.

4. When calling mv88e6390_serdes_irq_enable() we use the lane value
   belonging to the old cmode. Get the lane belonging to the new cmode
   before calling this function.

It's hard to provide a good "Fixes" tag because quite a few smaller
changes have been done to the code in question recently.
