Currently, driver supports flow classification to PF
receive queues based on TCP/UDP 4 tuples [src_ip, dst_ip,
src_port, dst_port] only.
This patch enables to configure different flow profiles
[For example - only UDP dest port or src_ip based] on the
adapter so that classification can be done according to
just those fields as well. Although, at a time just one
type of flow configuration is supported due to limited
number of flow profiles available on the device.
For example -
ethtool -N enp7s0f0 flow-type udp4 dst-port 45762 action 2
ethtool -N enp7s0f0 flow-type tcp4 src-ip 192.16.4.10 action 1
ethtool -N enp7s0f0 flow-type udp6 dst-port 45762 action 3

MFW requests the TLVs in interrupt context. Extracting of the required
data from upper layers and populating of the TLVs require process context.
The patch adds work-queues for processing the tlv requests. It also adds
the implementation for requesting the tlv values from appropriate protocol
driver.

The patch adds driver support for processing TLV requests/repsonses
from the mfw and upper driver layers respectively. The implementation
reads the requested TLVs from the shared memory, requests the values
from upper layer drivers, populates this info (TLVs) shared memory and
notifies MFW about the TLV values.

ILT entry requires 12 bit right shifted physical address.
Existing mask for ILT entry of physical address i.e.
ILT_ENTRY_PHY_ADDR_MASK is not sufficient to handle 64bit
address because upper 8 bits of 64 bit address were getting
masked which resulted in completer abort error on
PCIe bus due to invalid address.
Fix that mask to handle 64bit physical address.

The bpf syscall and selftests conflicts were trivial
overlapping changes.
The r8169 change involved moving the added mdelay from 'net' into a
different function.
A TLS close bug fix overlapped with the splitting of the TLS state
into separate TX and RX parts. I just expanded the tests in the bug
fix from "ctx->conf == X" into "ctx->tx_conf == X && ctx->rx_conf

This patch adds driver changes for supporting the Unified Fabric Port
(UFP). This is a new paritioning mode wherein MFW provides the set of
parameters to be used by the device such as traffic class, outer-vlan
tag value, priority type etc. Drivers receives this info via notifications
from mfw and configures the hardware accordingly.

`mf_mode' field indicates the multi-partitioning mode the device is
configured to. This method doesn't scale very well, adding a new MF mode
requires going over all the existing conditions, and deciding whether those
are needed for the new mode or not.
The patch defines a set of bit-fields for modes which are derived according
to the mode info shared by the MFW and all the configuration would be made
according to those. To add a new mode, there would be a single place where
we'll need to go and choose which bits apply and which don't.

prevent passing the length of the source buffer to strncpy() and guarantee
null termination.

There may be a need for VF driver to request PF to explicitly update its
bulletin with a MAC address.
e.g. When user assigns a MAC address to VF while VF is still down,
and PF's bulletin board contains different MAC address, in this case,
when VF's interface is brought up, it gets loaded with MAC address from
bulletin board which is not desirable.
To handle this corner case, we need a new TLV to request PF to update
its bulletin board with suggested MAC.
This request will be honored only for trusted VFs.

As per existing behavior, when PF sets a MAC address for a VF
(also called as forced MAC), VF is not allowed to change its
MAC address afterwards.
This puts the limitation on few use cases such as bonding of VFs,
where bonding driver asks VF to change its MAC address.
This patch uses a VF trust mode to allow VF to change its MAC address
in spite PF has set a forced MAC for that VF.

Fun set of conflict resolutions here...
For the mac80211 stuff, these were fortunately just parallel
adds. Trivially resolved.
In drivers/net/phy/phy.c we had a bug fix in 'net' that moved the
function phy_disable_interrupts() earlier in the file, whilst in
'net-next' the phy_error() call from this function was removed.
In net/ipv4/xfrm4_policy.c, David Ahern's changes to remove the
'rt_table_id' member of rtable collided with a bug fix in 'net' that
added a new struct member "rt_mtu_locked" which needs to be copied
over here.
The mlxsw driver conflict consisted of net-next separating
the span code and definitions into separate files, whilst
a 'net' bug fix made some changes to that moved code.
The mlx5 infiniband conflict resolution was quite non-trivial,
the RDMA tree's merge commit was used as a guide here, and
here are their notes:
====================
Due to bug fixes found by the syzkaller bot and taken into the for-rc
branch after development for the 4.17 merge window had already started
being taken into the for-next branch, there were fairly non-trivial
merge issues that would need to be resolved between the for-rc branch
and the for-next branch. This merge resolves those conflicts and
provides a unified base upon which ongoing development for 4.17 can
be based.
Conflicts:
drivers/infiniband/hw/mlx5/main.c - Commit 42cea83f9524
(IB/mlx5: Fix cleanup order on unload) added to for-rc and
commit b5ca15ad7e61 (IB/mlx5: Add proper representors support)
add as part of the devel cycle both needed to modify the
init/de-init functions used by mlx5. To support the new
representors, the new functions added by the cleanup patch
needed to be made non-static, and the init/de-init list
added by the representors patch needed to be modified to
match the init/de-init list changes made by the cleanup
patch.
Updates:
drivers/infiniband/hw/mlx5/mlx5_ib.h - Update function
prototypes added by representors patch to reflect new function
names as changed by cleanup patch
drivers/infiniband/hw/mlx5/ib_rep.c - Update init/de-init
stage list to match new order from cleanup patch

Rdma requires ILT Memory to be allocated for it's QPs.
Each ILT entry points to a page used by several Rdma QPs.
To avoid allocating all the memory in advance, the rdma
implementation dynamically allocates memory as more QPs are
added, however it does not dynamically free the memory.
The memory should have been freed on rmmod qedr, but isn't.
This patch adds the memory freeing on rmmod qedr (currently
it will be freed with qed is removed).
An outcome of this bug, is that if qedr is unloaded and loaded
without unloaded qed, there will be no more RoCE traffic.
The reason these are related, is that the logic of detecting the
first QP ever opened is by asking whether ILT memory for RoCE has
been allocated.
In addition, this patch modifies freeing of the Task context to
always use the PROTOCOLID_ROCE and not the protocol passed,
this is because task context for iWARP and ROCE both use the
ROCE protocol id, as opposed to the connection context.
