There will be BUG_ON() triggered in include/linux/skbuff.h leading to
intermittent kernel panic, when the skb length underflow is detected.
Fix this by dropping the packet if such length underflows are seen
because of inconsistencies in the hardware descriptors.

Some older NIC hardware isn't capable of doing VLAN push on RX and pop
on TX.
A workaround has been added in software to support it, but it has a
performance penalty since it requires a hairpin + loopback.
There's no such limitation with the newer NICs, so no need to pay the
price of the w/a. With this change the software w/a is disabled for
certain HW versions and steering modes that support it.

There are two different internal steering modes, abstracted from the
rest of the driver. In order to keep upper layer of the driver agnostic
to the differences in capabilities of the steering modes, this patch
introduces mlx5_fs_get_capabilities() API to check if a certain software
defined capability is supported. It differs from the capabilities
exposed by the hardware, as it takes into account the flow steering mode
(SMFS/DMFS) currently enabled.
This implementation supports only two capability flags:
MLX5_FLOW_STEERING_CAP_VLAN_PUSH_ON_RX
MLX5_FLOW_STEERING_CAP_VLAN_POP_ON_TX
They map to DR_ACTION_STATE_PUSH_VLAN and DR_ACTION_STATE_POP_VLAN
actions, implemented in SW steering earlier in commit f5e22be534e0
("net/mlx5: DR, Split modify VLAN state to separate pop/push states").
Which enables using of pop/push vlan without restrictions, e.g. doing
vlan pop on TX and RX, compared to FW steering that supports only vlan
pop on RX and push on TX.
Other capabilities can be added in the future.

ct clear action is a normal flow with a modify header for registers to

In later commit we are going to instantiate multiple attr instances
for flow instead of single attr.
Parsing TC sample allocates a new memory but there is no symmetric
cleanup in the infrastructure.
To avoid asymmetric alloc/free use sample_attr as part of the flow attr
and not allocated and held as a pointer.
This will avoid a cleanup leak when sample action is not on the first
attr.

A failing usercopy of the fence_rep object will lead to a stale entry in
the file descriptor table as put_unused_fd() won't release it. This
enables userland to refer to a dangling 'file' object through that still
valid file descriptor, leading to all kinds of use-after-free
exploitation scenarios.
Fix this by deferring the call to fd_install() until after the usercopy
has succeeded.

Pull rpmsg fixes from Bjorn Andersson:
"The cdev cleanup in the rpmsg_char driver was not performed properly,
resulting in unpredicable behaviour when the parent remote processor
is stopped with any of the cdevs open by a client.
Two patches transitions the implementation to use cdev_device_add()
and cdev_del_device(), to capture the relationship between the two
objects, and relocates the incorrectly placed cdev_del()"

Upon error the ieee802154_xmit_complete() helper is not called. Only
ieee802154_wake_queue() is called manually. We then leak the skb
structure.
Free the skb structure upon error before returning.
