Currently the driver support only ethernet eswitch, and we want to
protect downstream IPoIB netdev from trying to access it in IB link.

In order to have different RX handler per profile, fix and refactor the
current code to take the rx handler directly from the netdevice profile
rather than computing it on runtime as it was done with the switchdev
mode representor rx handler.
This will also remove the current wrong assumption in mlx5e_alloc_rq
code that mlx5e_priv->ppriv is of the type vport_rep.

Implement mlx5e's IPoIB SKB transmit using the helper functions provided
by mlx5e ethernet tx flow, the only difference in the code between
mlx5e_xmit and mlx5i_xmit is that IPoIB has some extra fields to fill
(UD datagram segment) in the TX descriptor (WQE) and it doesn't need to
have any vlan handling.

Like the mlx5e ethernet mode, on IPoIB mode we need to create RX steering
tables, but IPoIB do not require MAC and VLAN steering tables so the
only tables we create in here are:
1. TTC Table (Traffic Type Classifier table for RSS steering)
2. ARFS Table (for accelerated RFS support)
Creation of those tables is identical to mlx5e ethernet mode, hence the
use of mlx5e_create_ttc_table and mlx5e_arfs_create_tables.

In preparation for mlx5e RDMA net_device support, here we generalize
mlx5e_attach/detach in a way that those functions will be agnostic
to link type. For that we move ethernet specific NIC net device logic out
of those functions into {nic,rep}_{enable/disable} mlx5e NIC and
representor profiles callbacks.
Also some of the logic was moved only to NIC profile since it is not right
to have this logic for representor net device (e.g. set port MTU).

Or Gerlitz says:
====================
mlx5e-pedit 2017-03-28
This series adds support for offloading modifications of packet headers using
ConnectX-5 HW header re-write as an action applied during packet steering.
The offloaded SW mechanism is TC's pedit action. The offloading is
supported for E-Switch steering of VF traffic in the SRIOV
switchdev mode and for NIC (non eswitch) RX.
One use-case for this offload on virtual networks, is when the hypervisor
implements flow based router such as Open-Stack's DVR, where L2 headers
of guest packets re-written with routers' MAC addresses and the IP TTL
is decremented.
Another use case (which can be applied in parallel with routing) is
stateless NAT where guest L3/L4 headers are re-written.
The series is built as follows: the 1st six patches are preperations which
don't yet add new functionality, patches 7-8 add the FW APIs (data-structures
and commands) for header re-write, and patch nine allows offloading driver
to access pedit keys.
The 10th patch is somehow the core of the series, where we translate from
the pedit way to represent set of header modification elements to the FW
API for that same matter.
Once a set of HW modification is established, we register it with the FW
and get a modify header ID. When this ID is used with an action during
packet steering, the HW applies the header modification on the packet.
Patches 11 and 12 implement the above logic as an offload for pedit action
for the NIC and E-Switch use-cases.
I'd like to thanks Elijah Shakkour <elijahs@mellanox.com> for implementing
and helping me testing this functionality on HW simulator, before it could
be done with FW.

Parse/translate a set of TC pedit actions to be formed in the HW API format.
User-space provides set of keys where each one of them is made of: command (add or
set), header-type, byte offset within that header along with a 32 bit mask and value.
The mask dictates what bits in the 32 bit word that starts on the offset we should
be dealing with, but under negative polarity (unset bits are to be modified).
We do a 1st pass over the set of keys while using the header-type and offset to
fill the masks and the values into a data-structure containting all the
supported network headers.
We then do a 2nd pass over the set of fields to re-write supported by the HW,
where for each such candidate field, we use the masks filled on the 1st pass to
realize if we should offloading re-write it.
In case offloading is required, we fill a HW descriptor with the following:
(1) the header field to modify
(2) the bit offset within the field from where to modify (set command only)
(3) the value to set/add
(4) the length in bits 1...32 to modify (set command only)
Note that it's possible for a given pedit mask to dictate modifying the
same header field multiple times or to modify multiple header fields.
Currently such combinations are not supported for offloading, hence, for set
commands, the offset within the field is always zero, and the length to modify
is the field size.

The code for adding tc fdb flows leaves things half set when it fails
in the middle. Currently we are not leaking things (e.g eswitch
vlan reference, encap reference and HW resources) since the main
code to add flower rules does a cleanup by calling mlx5e_tc_del_flow().
This cleanup further works just b/c we're checking there if the HW rule
for the flow we are attempting to delete is valid before touching it, and
since under the current possible combinations of supported actions it's okay
to go and blidnly deref or delete all the action related resources (encap, vlan).
Instead, do things properly, namely make sure that if add flow fails we
clean all what was allocated or referenced. Now, the flow delete code can
blindly deref/deallocate both the rule and the actions related resources and
when more action combinations are introduced (such as the upcoming header
re-write) we are fine with clear and robust code.
While here, align all of nic/fdb parse actions/add flow functions to get
mlx5e_tc_flow struct param and pick the attributes or whatever else needed
from there.

Use the new fail-safe channels switch mechanism to set new
netdev mtu and lro settings.
MTU and lro settings demand some HW configuration changes after new
channels are created and ready for action. In order to unify switch
channels routine for LRO and MTU changes, and maybe future configuration
features, we now pass to it a modify HW function pointer to be
invoked directly after old channels are de-activated and before new
channels are activated.
