This patch cleans up promiscuous configuration when a VF reset occurs.
Previously the promiscuous mode settings were still there after the VF
driver removal.

This resolves an issue where the VF link state was not being updated

Clear ADDR64 dma bit in DMACFG register in case that HW_DMA_CAP_64B is
not detected on 64bit system.
The issue was observed when bootloader(u-boot) does not check macb
feature at DCFG6 register (DAW64_OFFSET) and enabling 64bit dma support
by default. Then macb driver is reading DMACFG register back and only
adding 64bit dma configuration but not cleaning it out.

The check for pci_is_pcie() is redundant here because all
chip versions >=18 are PCIe only anyway. In addition use
dma_set_mask_and_coherent() instead of separate calls to
pci_set_dma_mask() and pci_set_consistent_dma_mask().

Until now, the Rx flow hash key was a 5-tuple (IP src, IP dst,
IP nextproto, L4 src port, L4 dst port) fixed value that we
configured at probe.
Add support for configuring this hash key at runtime.
We support all standard header fields configurable through ethtool,
but cannot differentiate between flow types, so the same hash key
is applied regardless of protocol.
We also don't support the discard option.

With CONFIG_DMA_API_DEBUG enabled we get DMA unmapping warning in
various places of the mvneta driver, for example when putting down an
interface while traffic is passing through.
The issue is when using s/w buffer management, the Rx buffers are mapped
using dma_map_page but unmapped with dma_unmap_single. This patch fixes
this by using the right unmapping function.

The SPI protocol for the QCA7000 doesn't have any fault detection.
In order to increase the drivers reliability in noisy environments,
we could implement a write verification inspired by the enc28j60.
This should avoid situations were the driver wrongly assumes the
receive interrupt is enabled and miss all incoming packets.
This function is disabled per default and can be controlled via module
parameter wr_verify.

This commit allows each TXQ to be picked in a round-robin fashion by

This patch fixes skb_shared area, which will be corrupted
upon reception of 4K jumbo packets.
Originally build_skb usage purpose was to reuse page for skb to eliminate
needs of extra fragments. But that logic does not take into account that
skb_shared_info should be reserved at the end of skb data area.
In case packet data consumes all the page (4K), skb_shinfo location
overflows the page. As a consequence, __build_skb zeroed shinfo data above
the allocated page, corrupting next page.
The issue is rarely seen in real life because jumbo are normally larger
than 4K and that causes another code path to trigger.
But it 100% reproducible with simple scapy packet, like:
sendp(IP(dst="192.168.100.3") / TCP(dport=443) \
/ Raw(RandString(size=(4096-40))), iface="enp1s0")

As diagnosed by Song Liu, ndo_poll_controller() can
be very dangerous on loaded hosts, since the cpu
calling ndo_poll_controller() might steal all NAPI
contexts (for all RX/TX queues of the NIC). This capture
can last for unlimited amount of time, since one
cpu is generally not able to drain all the queues under load.
tun uses NAPI for TX completions, so we better let core
networking stack call the napi->poll() to avoid the capture.

Up until now, mlxsw tolerated firmware versions that weren't exactly
matching the required version, if the branch number matched. That
allowed the users to test various firmware versions as long as they were
on the right branch.
On the other hand, it made it impossible for mlxsw to put a hard lower
bound on a version that fixes all problems known to date. If a user had
a somewhat older FW version installed, mlxsw would start up just fine,
possibly performing non-optimally as it would use features that trigger
problematic behavior.
Therefore tweak the check to accept any FW version that is:
- on the same branch as the preferred version, and
- the same as or newer than the preferred version.

There are two tqp_num variables "hdev->tqp_num" and "kinfo->tqp_num"
used in VF. "hdev->tqp_num" is the total tqp number allocated to the
VF, and "kinfo->tqp_num" indicates the tqp number being used by the
VF. Usually the two variables are equal. But for the case hdev->tqp_num
larger than rss_size_max, and num_tc is 1, "kinfo->tqp_num" will be
less than "hdev->tqp_num".
In original codes, "hdev->tqp_num" is always used to traverse the

The previous commit to ravb had the side effect of making the PHY
advertise Pause and Asym Pause, which previously did not happen. By
default, phydev->supported has both forms of pause enabled, but
phydev->advertising does not. The new phy_remove_link_mode() copies
phydev->supported to phydev->advertising after removing the requested
link mode. These Pause configuration bits appears it stops the PHY
from completing Auto-Neg and the link remains down. Be explicit and
remove the Pause and Asym Pause modes, so restoring the old behavior.
