As pointed out by Jamal, an action could be shared by
multiple filters, so we can't use list to chain them
any more after we get rid of the original tc_action.
Instead, we could just save pointers to these actions
in tcf_exts, since they are refcount'ed, so convert
the list to an array of pointers.
The "ugly" part is the action API still accepts list
as a parameter, I just introduce a helper function to
convert the array of pointers to a list, instead of
relying on the C99 feature to iterate the array.

Intel Wired LAN Driver Updates 2016-08-16
This series contains fixes to e1000e, igb, ixgbe and i40e.
Kshitiz Gupta provides a fix for igb to resolve the PHY delay compensation
math in several functions.
Jarod Wilson provides a fix for e1000e which had to broken up into 2
patches, first is prepares the driver for expanding the list of NICs
that have occasional ~10 hour clock jumps when being used for PTP.
Second patch actually fixes i218 silicon which has been experiencing
the clock jumps while using PTP.
Alex provides 2 patches for ixgbe now that he is back at Intel. First
fixes setting VLNCTRL.VFE bit, which was left unchanged in earlier patches
which resulted in disabling VLAN filtering for all the VFs. Second
corrects the support for disabling the VLAN tag filtering via the
feature bit.
Lastly, David fixes i40e which was causing a kernel panic when
non-contiguous traffic classes or traffic classes not starting with TC0,
were configured on a link partner switch. To fix this, changed the
logic when determining the total number of TCs enabled.

When packets enter the device they are classified to a priority group
(PG) buffer based on their PCP value. After their egress port and
traffic class are determined they are moved to the switch's shared
buffer and await transmission, if:
(Ingress{Port}.Usage < Thres && Ingress{Port,PG}.Usage < Thres &&
Egress{Port}.Usage < Thres && Egress{Port,TC}.Usage < Thres)
||
(Ingress{Port}.Usage < Min || Ingress{Port,PG} < Min ||
Egress{Port}.Usage < Min || Egress{Port,TC}.Usage < Min)
Packets scheduled to transmission through CPU port (trapped to CPU) use
traffic class 7, which has a zero maximum and minimum quotas. However,
when such packets arrive from PG 0 they are admitted to the shared
buffer as PG 0 has a non-zero minimum quota.
Allow all packets to be trapped to the CPU - regardless of the PG they
were classified to - by assigning a 10KB minimum quota for CPU port and
TC7.

One of the conditions to generate an ICMP Redirect Message is that "the

Therefore, we need to be able to trap such packets and let the kernel

Commit bbf2a4757b ("mlxsw: spectrum: Initialize ports at the end of
init sequence") moved ports initialization to the end of the init
sequence, which means ports are the first to be removed during fini.
Since the FDB delayed work is still active when ports are removed it's
possible for it to process FDB notifications of inactive ports,
resulting in a warning message.
Fix that by marking ports as inactive only after unregistering them. The
NETDEV_UNREGISTER event will invoke bridge's driver port removal
sequence that will cause the FDB (and FDB notifications) to be flushed.

The i40e driver was causing a kernel panic when
non-contiguous Traffic Classes, or Traffic Classes not
starting with TC0, were configured on a link partner switch.
i40e does not support non-contiguous TCs.
To fix this, the patch changes the logic when determining
the total number of TCs enabled. Before, this would use the
highest TC number enabled and assume that all TCs below it were
also enabled. Now, we create a bitmask of enabled TCs and scan
it to determine not only the number of TCs, but also if the set
of enabled TCs starts at zero and is contiguous. If not, then
DCB is disabled by only returning one TC.

Fix PHY delay compensation math in igb_ptp_tx_hwtstamp() and
igb_ptp_rx_rgtstamp. Add PHY delay compensation in
igb_ptp_rx_pktstamp().
In the IGB driver, there are two functions that retrieve timestamps
received by the PHY - igb_ptp_rx_rgtstamp() and igb_ptp_rx_pktstamp().
The previous commit only changed igb_ptp_rx_rgtstamp(), and the change
was incorrect.
There are two instances in which PHY delay compensations should be
made:
- Before the packet transmission over the PHY, the latency between
when the packet is timestamped and transmission of the packets,
should be an add operation, but it is currently a subtract.
- After the packets are received from the PHY, the latency between
the receiving and timestamping of the packets should be a subtract
operation, but it is currently an add.

Commit 08ef55c6f2
("net-next: mediatek: fix gigabit and flow control advertisement")
had supported proper flow control settings for GMAC1. But for GMAC0,
1.GMAC0 shares the common logic with GMAC1 inside mtk_phy_link_adjust()
to adapt various settings for the target phy.
2.GMAC0 uses fixed-phy to connect to a builtin gigabit switch with
fixed link speed as commit 0c72c50f6f
("net-next: mediatek: add fixed-phy support") describes.
3.However, fixed-phy doesn't enable SUPPORTED_Pause & SUPPORTED_Asym_Pause
supported flag on default that would cause mtk_phy_link_adjust() not to
enable flow control setting on GMAC0 properly and cause packet dropped
when high traffic.
Due to these reasons, the patch adds SUPPORTED_Pause & SUPPORTED_Asym_Pause

Commit b5a099c67a "net: ethernet: davicom: fix devicetree irq
resource" causes an interrupt storm after the ethernet interface
is activated on S3C24XX platform (ARM non-dt), due to the interrupt
trigger type not being set properly.
It seems, after adding parsing of IRQ flags in commit 7085a7401b
"drivers: platform: parse IRQ flags from resources", there is no path
for non-dt platforms where irq_set_type callback could be invoked when
we don't pass the trigger type flags to the request_irq() call.
In case of a board where the regression is seen the interrupt trigger
type flags are passed through a platform device's resource and it is
not currently handled properly without passing the irq trigger type
flags to the request_irq() call. In case of OF an of_irq_get() call
within platform_get_irq() function seems to be ensuring required irq_chip
setup, but there is no equivalent code for non OF/ACPI platforms.
This patch mostly restores irq trigger type setting code which has been
removed in commit ("net: ethernet: davicom: fix devicetree irq resource").

Driver modifies the supplied NAPI budget in qlcnic_83xx_msix_tx_poll()
function. Instead, it should use the budget as it is.

This patch fixes a data structure corruption bug in the SRIOV VF mailbox
handler code. While handling mailbox commands from the atomic context,
driver is accessing and updating qlcnic_async_work_list_struct entry fields
in the async work list. These fields could be concurrently accessed by the
work function resulting in data corruption.
This patch restructures async mbx command handling by using a separate
async command list instead of using a list of work_struct structures.
A single work_struct is used to schedule and handle the async commands
with proper locking mechanism.

This patch remove the wrong substraction from info->data in
tg3_get_rxnfc function. Without this patch, the number of RSS
queues reported is less by one.

When the rx coalescing time is 0, interrupts
are not generated from the controller and rx path hangs.
To avoid this rx hang, updating the driver to not allow
rx coalescing time to be 0.

Building with -Wmaybe-uninitialized shows a potential use of
an uninitialized variable:
drivers/net/ethernet/apm/xgene/xgene_enet_hw.c: In function 'xgene_enet_phy_connect':
drivers/net/ethernet/apm/xgene/xgene_enet_hw.c:802:23: warning: 'phy_dev' may be used uninitialized in this function [-Wmaybe-uninitialized]
Although the compiler correctly identified this based on the function,
the current code is still safe as long dev->of_node is non-NULL
for the case of CONFIG_ACPI=n, which is currently the case.
The warning is now disabled by default, but still appears when
building with W=1, and other build test tools should be able to
detect it as well. Adding an #else clause here makes the code
more robust and makes it clear to the compiler that this cannot
happen.
