The be_fill_queue() function can only fail when "eq_vaddress" is NULL and
since it's non-NULL here that means the function call can't fail. But
imagine if it could, then in that situation we would want to store the
"paddr" so that dma memory can be released.

dpaa2-eth: add devlink parser error drop trap support
This patch set adds support in the dpaa2-eth driver for a new group of
devlink drop traps - PARSER_ERROR_DROPS.
The first patch adds a new generic trap group and associated traps,
their definitions in devlink and their corresponding entries in the
Documentation.
Because there might be more devices (besides DPAA2) which do not support
changing the action independently on each trap, a nre devlink callback
is introduced - .trap_group_action_set(). If this callback is populated,
it will take precedence over .trap_action_set() when the user requests
changing the action on all the traps in a group.
The next patches add basic linkage with devlink for the dpaa2-eth driver
and support for the newly added PARSER_ERROR_DROPS. Nothing special
here, just setting up the Rx error queue, interpreting the parse result,
and then reporting any frame received on that queue to devlink.
Changes in v2:
- fix build error in 3/4
Changes in v3:
- removed a commented line in 4/4
- added an extack in 4/4
- fixed up a warning on 32bit in 4/4
- reworded the trap_group_action_set() description in 2/4

Add support for the new group of devlink traps - PARSER_ERROR_DROPS.
This consists of registering the array of parser error drops supported,
controlling their action through the .trap_group_action_set() callback
and reporting an erroneous skb received on the error queue
appropriately.
DPAA2 devices do not support controlling the action of independent
parser error traps, thus the .trap_action_set() callback just returns an
EOPNOTSUPP while .trap_group_action_set() actually notifies the hardware
what it should do with a frame marked as having a header error.

out the q and cq descriptor allocations. That patch was aimed at
making the big tx and rx descriptor queue allocations easier to
manage - the notifyq is much smaller and doesn't need to be split.
This patch simply adds an if/else and slightly different code for

from right there, but
1. it's getting more & more complicated to cover all cases, and
2. we can't re-enable the actually expected number of TX queues later
because we lost the needed information.

its changed via .set_channels), and later use that information when
re-enabling the netdevice.

Some iSCSI targets went with the traditional "export N ports" approach and
then allowed the initiator to multipath over them. Other targets went the
opposite direction and export a single port, and then software on the
target side performs load balancing and failover to other targets via an
iSCSI specific feature or IP takover.
The problem for the 2nd type of config is we quickly run out of our five
retries and get I/O errors. In these setups we want to reduce resource use
on the initiator side so we only wanted the one session and no
dm-multipath. To handle traditional multipath operations like failover we
do IP takover on the target side. So we would have an iSCSI target running
on node1. Some monitoring software decides it's dead or the node is
overloaded so it starts the iSCSI target on node2. The problem is for the
failover case where we might have the equivalent of a dm-multipath
temporary all paths down, or we just have to try more than 5 nodes before
finding a good one.
To handle this type of issue allow the user to configure the disk cmd
retries from -1 to the current max of 5. -1 means infinite retries and
should be used for setups where some other setting is going to control when
to fail. For example iSCSI has the replacement/recovery timeout and fc
(some users have used FC with NPIV and done something similar as IP
takover) has dev_loss_tmo/fast_io_fail which will eventually expire and
fail I/O.

Provide an example script which can be used as a skeleton for offloading
TCAM rules in the Ocelot switches.
Not all actions are demoed, mostly because of difficulty to automate
this from a single board.
For example, policing. We can set up an iperf3 UDP server and client and
measure throughput at destination. But at least with DSA setups, network
namespacing the individual ports is not possible because all switch
ports are handled by the same DSA master. And we cannot assume that the
target platform (an embedded board) has 2 other non-switch generator
ports, we need to work with the generator ports as switch ports (this is
the reason why mausezahn is used, and not IP traffic like ping). When
somebody has an idea how to test policing, that can be added to this
test.

Via the OCELOT_MASK_MODE_REDIRECT flag put in the IS2 action vector, it
is possible to replace previous forwarding decisions with the port mask
installed in this rule.
I have studied Table 54 "MASK_MODE and PORT_MASK Combinations" from the
VSC7514 documentation and it appears to behave sanely when this rule is
installed in either lookup 0 or 1. Namely, a redirect in lookup 1 will
overwrite the forwarding decision taken by any entry in lookup 0.

The issue which led to the introduction of this check was that MAC_ETYPE
rules, such as filters on dst_mac and src_mac, would only match non-IP
frames. There is a knob in VCAP_S2_CFG which forces all IP frames to be
treated as non-IP, which is what we're currently doing if the user
requested a dst_mac filter, in order to maintain sanity.
But that knob is actually per IS2 lookup. And the good thing with
exposing the lookups to the user via tc chains is that we're now able to
