The result of __dev_get_by_index() is not checked for NULL and then gets
dereferenced immediately.
Also, __dev_get_by_index() must be called while holding either RTNL lock
or @dev_base_lock, which isn't satisfied by mlx5e_hairpin_get_mdev() or
its callers. This makes the underlying hlist_for_each_entry() loop not
safe, and can have adverse effects in itself.
Fix by using dev_get_by_index() and handling nullptr return value when
ifindex device is not found. Update mlx5e_hairpin_get_mdev() callers to
check for possible PTR_ERR() result.

When HW aggregates packets for an LRO session, it writes the payload
of two consecutive packets of a flow contiguously, so that they usually
share a cacheline.
The first byte of a packet's payload is written immediately after
the last byte of the preceding packet.
In this flow, there are two consecutive write requests to the shared
cacheline:
1. Regular write for the earlier packet.
2. Read-modify-write for the following packet.
In case of relaxed-ordering on, these two writes might be re-ordered.
Using the end padding optimization (to avoid partial write for the last
cacheline of a packet) becomes problematic if the two writes occur
out-of-order, as the padding would overwrite payload that belongs to
the following packet, causing data corruption.
Avoid this by disabling the end padding optimization when both
LRO and relaxed-ordering are enabled.

Separate these from the few drivers that use ndo_do_ioctl to

Currently, all drivers depend on the bool CONFIG_NET_SWITCHDEV, but only
the drivers that call some sort of function exported by the bridge, like
br_vlan_enabled() or whatever, have an extra dependency on CONFIG_BRIDGE.
Since the blamed commit, all switchdev drivers have a functional
dependency upon switchdev_bridge_port_{,un}offload(), which is a pair of
functions exported by the bridge module and not by the bridge-independent
part of CONFIG_NET_SWITCHDEV.
Problems appear when we have:
CONFIG_BRIDGE=m
CONFIG_NET_SWITCHDEV=y
CONFIG_TI_CPSW_SWITCHDEV=y
because cpsw, am65_cpsw and sparx5 will then be built-in but they will
call a symbol exported by a loadable module. This is not possible and
will result in the following build error:
drivers/net/ethernet/ti/cpsw_new.o: in function `cpsw_netdevice_event':
drivers/net/ethernet/ti/cpsw_new.c:1520: undefined reference to
`switchdev_bridge_port_offload'
drivers/net/ethernet/ti/cpsw_new.c:1537: undefined reference to
`switchdev_bridge_port_unoffload'
As mentioned, the other switchdev drivers don't suffer from this because
switchdev_bridge_port_offload() is not the first symbol exported by the
bridge that they are calling, so they already needed to deal with this
in the same way.

This series aims to reduce coupling in mlx5e, particularly between RX

This refactoring is required for upcoming features, ADQ and TX lag
hashing.
The issue with the current code is that TIRs and RQTs are unmanaged,
different places all over the driver create, destroy, track and
configure them, often in an uncoordinated way. The responsibilities of
different units become vague, leading to a lot of hidden dependencies
between numerous units and tight coupling between them, which is prone
to bugs and hard to maintain.
The result of this refactoring is:
1. Creating a manager for RX resources, that controls their lifecycle
and provides a clear API, which restricts the set of actions that other
units can do.
2. Using object-oriented approach for TIRs, RQTs and RX resource

3. Fixing a few bugs and misbehaviors found during the refactoring.
4. Reducing the amount of dependencies, removing hidden dependencies,
making them one-directional and organizing the code in clear abstraction
layers.
5. Explicitly exposing the remaining weird dependencies.
6. Simplifying and organizing code that creates and modifies TIRs and
RQTs.
