be2net: Fix pcie error recovery in case of NIC+RoCE adapters
Interrupts registered by RoCE driver are not unregistered when
msix interrupts are disabled during error recovery causing a
crash. Detach the adapter instance from RoCE driver when error
is detected to complete the cleanup. Attach the driver again after
the adapter is recovered from error.

All of the i40e (XL710/X710) 10/20/40GbE NICs lack support for indicating
INTx is asserted via the interrupt bit in the PCI status register. The
DisINTx bit in the command register is functional, causing these devices to
be incorrectly detected as supporting INTx masking. Quirk them to properly
indicate no INTx masking support.

Previously we were only looking at the FW supported PHY types if link
was down, because we want to be more specific when link is up. This
refactor changes this. When link is down, we still rely on the FW
supported PHY types, but when link is up, we select the possible
supported link modes from what we know about the current PHY type, and
AND that with the FW supported PHY types.

This patch adds priv-flag knob to configure global true promisc
support. With this patch the user can decide the flavor of
promiscuous that the VFs will see when promiscuous mode is enabled
on the interface. Since this a global setting for the whole device,
the priv-flag is exposed only on the first PF of the device.
The default is true promisc support is off, which means the promisc
mode for the VF will be limited/defport mode.
For the PF, we still will be in limited promisc unless in MFP mode
irrespective of the flavor picked through this knob.
Usage:
On PF0
ethtool --show-priv-flags p261p1
Private flags for p261p1:
MFP : off
LinkPolling : off
flow-director-atr : on
veb-stats : off
hw-atr-eviction : off
vf-true-promisc-support: off
to enable setting true promisc
ethtool --set-priv-flags p261p1 vf-true-promisc-support on
At this point if the VF is set to trust and promisc is enabled
on the VF through
ip link set ... promisc on
The VF/VFs will be able to see ALL ingress traffic

When testing on systems with very limited amounts of RAM, a bug was
found where, while changing the number of descriptors using ethtool,
the driver didn't test the limits of system memory before permanently
assuming it would be able to get receive buffer memory.
Work around this issue by pre-allocation of the receive buffer
memory, in the "ghost" ring, which is then used during reinit
using the new ring length.

The hardware supports a 16 byte descriptor for receive, but the
driver was never using it in production. There was no performance
benefit to the real driver of 16 byte descriptors, so drop a whole
lot of complexity while getting rid of the code.
Also since the previous patch made us use no-split mode all the
time, drop any support in the driver for any other value in dtype
and assume it is always zero (aka no-split).
Hooray for code removal!

This is part 2 of the Rx refactor series, just including
changes to i40evf.
This refactor aligns the receive routine with the one in
ixgbe which was highly optimized. This reduces the code
we have to maintain and allows for (hopefully) more readable
and maintainable RX hot path.
In order to do this:
- consolidate the receive path into a single function that doesn't
use packet split but *does* use pages for Rx buffers.
- remove the old _1buf routine
- consolidate several routines into helper functions
- remove VF ethtool control over packet split
- remove priv_flags interface since it is unused

If the VF is privileged/trusted it can do as it may please including
but not limited to hogging resources and playing unfair.
But if the VF is not privileged/trusted it still can add some number
(8) of MAC and VLAN addresses.
Other restrictions with respect to Port VLAN and normal VLAN still apply
to not privileged/trusted VF.

If the PF driver reports proper support, allow the PF driver to
configure RSS on the behalf of the VF driver. This will allow for RSS
support on future hardware without changes to the VF driver.
Unfortunately, the old RSS code still needs to stay as the driver needs
to be compatible with PF drivers that don't support this interface. But
this change still simplifies the data structures a bunch and makes this
code simpler to read and maintain.

The feature flags list for i40e and i40evf is beginning to become pretty
massive. I plan to add another 4 or so features to these drivers and
duplicating the flags for each and every flags list is becoming a bit
repetitive.
The primary change here is that we now build our features list around
hw_encap_features. After that we assign that to vlan_features,
hw_features, and finally map that onto features. In addition we end up
throwing features onto hw_encap_features that end up having no effect such
as the Rx offloads and SCTP_CRC. However that should have no impact and
makes things a bit easier for us as hw_encap_features is one of the less
updated features maps available.
For i40evf I went through and sanity checked a few features as well.
Specifically RXCSUM was being set as a read-only feature which didn't make
much sense. I have updated things so we can clear the NETIF_F_RXCSUM flag
since that is really a software feature and not a hardware one anyway so
disabling it is just a matter of ignoring the result from the hardware.

If the driver happens to read a register during the time in which the
device is undergoing reset, it will receive a value of 0xdeadbeef
instead of a valid value. Unfortunately, the driver may misinterpret
this as a valid value, especially if it's just looking for individual
bits.
Add an explicit check for this value when we are looking for admin queue
errors, and trigger reset recovery if we find it.

In the polling routines for i40e and i40evf we were using bitwise operators
to avoid the side effects of the logical operators, specifically the fact
that if the first case is true with "||" we skip the second case, or if it
is false with "&&" we skip the second case. This fixes an earlier patch
that converted the bitwise operators over to the logical operators and
instead replaces the entire thing with just an if statement since it should
be more readable what we are trying to do this way.

From what I can tell the practical limitation on the size of the Tx data
buffer is the fact that the Tx descriptor is limited to 14 bits. As such
we cannot use 16K as is typically used on the other Intel drivers. However
artificially limiting ourselves to 8K can be expensive as this means that
we will consume up to 10 descriptors (1 context, 1 for header, and 9 for
payload, non-8K aligned) in a single send.
I propose that we can reduce this by increasing the maximum data for a 4K
aligned block to 12K. We can reduce the descriptors used for a 32K aligned
block by 1 by increasing the size like this. In addition we still have the
4K - 1 of space that is still unused. We can use this as a bit of extra
padding when dealing with data that is not aligned to 4K.
By aligning the descriptors after the first to 4K we can improve the
efficiency of PCIe accesses as we can avoid using byte enables and can fetch
full TLP transactions after the first fetch of the buffer. This helps to
improve PCIe efficiency. Below is the results of testing before and after
with this patch:
Recv Send Send Utilization Service Demand
Socket Socket Message Elapsed Send Recv Send Recv
Size Size Size Time Throughput local remote local remote
bytes bytes bytes secs. 10^6bits/s % S % U us/KB us/KB
Before:
87380 16384 16384 10.00 33682.24 20.27 -1.00 0.592 -1.00
After:
87380 16384 16384 10.00 34204.08 20.54 -1.00 0.590 -1.00
So the net result of this patch is that we have a small gain in throughput
due to a reduction in overhead for putting together the frame.

Calling dev_close() causes IFF_UP to be cleared which will remove the
interfaces routes and some addresses. That's probably not what the user
intended when running the offline selftest. Besides this does not happen
if the interface is brought down before the test, so the current
behaviour is inconsistent.
Instead call the net_device_ops ndo_stop function directly and avoid
touching IFF_UP at all.

This patch addresses a bug introduced based on my interpretation of the
XL710 datasheet. Specifically section 8.4.1 states that "A single transmit
packet may span up to 8 buffers (up to 8 data descriptors per packet
including both the header and payload buffers)." It then later goes on to
say that each segment for a TSO obeys the previous rule, however it then
refers to TSO header and the segment payload buffers.
I believe the actual limit for fragments with TSO and a skbuff that has
payload data in the header portion of the buffer is actually only 7
fragments as the skb->data portion counts as 2 buffers, one for the TSO
header, and one for a segment payload buffer.
