Make sure to check the number of endpoints to avoid dereferencing a
NULL-pointer or accessing memory beyond the endpoint array should a
malicious device lack the expected endpoints.
The endpoints are specifically dereferenced in the i2400m_bootrom_init
path during probe (e.g. in i2400mu_tx_bulk_out).

Change packet type handler to ETH_P_IP instead of ETH_P_ALL
since we are already expecting an IP packet.
Also, using ETH_P_ALL will cause the loopback test packet type handler
to be called on all outgoing packets, especially our own self loopback
test SKB, which will be validated on xmit as well, and we don't want that.
Tested with:
ethtool -t ethX
validated that the loopback test passes.

When deleting offloaded TC flows, we must correctly identify E-switch
rules. The current check could get us wrong w.r.t to rules set on the
PF. Since it's possible to set NIC rules on the PF, switch to SRIOV
offloads mode and then attempt to delete a NIC rule.
To solve that, we add a flags field to offloaded rules, set it on
creation time and use that over the code where currently needed.

The autogroups list is a list of non overlapping group boundaries
sorted by their start index. If the autogroups list wasn't empty
and an empty group slot was found at the start of the list,
the new group was added to the end of the list instead of the
beginning, as the prev initializer was incorrect.
When this was repeated, it caused multiple groups to have
overlapping boundaries.
Fixed that by correctly initializing the prev pointer to the
start of the list.

not using a devm_hmon API, resulting in the device being removed

When using the internal PHY it must be powered up when the MII is probed
or the PHY will not be detected. Since the PHY is powered up at reset
this has not been a problem. However, when the kernel is restarted with
kexec the PHY will likely be powered down when the kernel starts so it
will not be detected and the Ethernet link will not be established.
This commit explicitly powers up the internal PHY when the GENET driver
is probed to correct this behavior.

ACPI support has been added to ARM IOMMU driver in 4.10 kernel
and that has resulted in VNIC interfaces throwing translation
faults when kernel is booted with ACPI as driver was not using
DMA API. This patch fixes the issue by using DMA API which inturn
will create translation tables when IOMMU is enabled.
Also VNIC doesn't have a seperate receive buffer ring per receive
queue, so there is no 1:1 descriptor index matching between CQE_RX
and the index in buffer ring from where a buffer has been used for
DMA'ing. Unlike other NICs, here it's not possible to maintain dma
address to virt address mappings within the driver. This leaves us
no other choice but to use IOMMU's IOVA address conversion API to
get buffer's virtual address which can be given to network stack
for processing.

Improve UDP TX performance by:
* reducing the ring size from 2K to 512
* replacing the numerous streaming DMA allocations for info buffers and
gather lists with one large consistent DMA allocation per ring
BQL is not effective here. We reduced the ring size because there is heavy
overhead with dma_map_single every so often. With iommu=on, dma_map_single
in PF Tx data path was taking longer time (~700usec) for every ~250
packets. Debugged intel_iommu code, and found that PF driver is utilizing
too many static IO virtual address mapping entries (for gather list entries
and info buffers): about 100K entries for two PF's each using 8 rings.
Also, finding an empty entry (in rbtree of device domain's iova mapping in
kernel) during Tx path becomes a bottleneck every so often; the loop to
find the empty entry goes through over 40K iterations; this is too costly
and was the major overhead. Overhead is low when this loop quits quickly.

This restores the ability to set a team device's mtu to anything higher
than 1500. Similar to the reported issue with bonding, the team driver
calls ether_setup(), which sets an initial max_mtu of 1500, while the
underlying hardware can handle something much larger. Just set it to
ETH_MAX_MTU to support all possible values, and the limitations of the
underlying devices will prevent setting anything too large.

The ethtool api {get|set}_settings is deprecated.
We move this driver to new api {get|set}_link_ksettings.
As I don't have the hardware, I'd be very pleased if
someone may test this patch.

The amount of TX/RX buffers that the vNIC driver currently allocates
is different from the amount agreed upon in negotiation with firmware.
Correct that by allocating the requested number of buffers confirmed
by firmware.

Use a counter to track the number of outstanding transmissions sent
that have not received completions. If the counter reaches the maximum
number of queue entries, stop transmissions on that queue. As we receive
more completions from firmware, wake the queue once the counter reaches
an acceptable level.
This patch prevents hardware/firmware TX queue from filling up and
and generating errors. Since incorporating this fix, internal testing
has reported that these firmware errors have stopped.

Configuring VLANs from the VF side had no effect, because the PF ignored
filters of type VFPF_VLAN_FILTER in the VF-PF message.
Add the missing filter type to configure.

filters->count is the number of filters we were supposed to configure.
There is no reason to increase it by +1 when printing the count in an error
message.
