This patch cleans up the use of dma_get_required_mask and uses the
simpler dma_set_mask_and_coherent function instead of doing these as
separate steps.
I removed the dma_get_required_mask call because based on some minimal
testing it appears that either (a) we're not doing the right thing with
the call or (b) we don't need it anyways. If the value returned is
<48bits, we'll end up trying with 48 bits anyways. If it's over 48bits,
fm10k can't support that anyways, and we should try 48bits. If 48bits
fails, we'll fallback to 32bits. This cleans up some very funky code.

l2_accel was checked for NULL at the top of fm10k_dfwd_del_station, and
we return if it is not defined. Due to this, we already know it can't be
null here so a separate check is meaningless. Discovered via cppcheck.

This prevents a memory leak in fm10k_set_ringparams. The leak occurs
because we go down, change ring parameters, and then come up. However,
fm10k_down on its own is not clearing the Rx rings. Since fm10k_up
assumes the rings are clean we basically drop the buffers and leak a
bunch of memory. Eventually we hit dirty page faults and reboot the
system. This issue does not occur elsewhere because other flows that
involve fm10k_down go through fm10k_close which immediately called
fm10k_free_all_rx_resources which properly cleans the rings.

This patch resolves a bug in the ts_tx_enqueue code responsible for a
NULL pointer dereference and invalid access of the skb list. We
incorrectly freed the actual skb we found instead of our copy. Thus the
skb queue is essentially invalidated. Resolve this by freeing our clone
in the cases where we did not add it to the queue. This also avoids the
skb memory leak caused by failure to free the clone.

skb_complete_tx_timestamp is intended for use by PHY drivers which
implement a different method of returning timestamps. This method is
intended to be used after a PHY driver accepts a cloned packet via its
phy_driver.txtstamp function. It is not correct to use in the standard
ethernet driver such as fm10k. This patch fixes the following possible
kernel panic.

This change fixes an issue with adding an invalid multicast address
using the iproute2 tool (ip maddr add <MADDR> dev <dev>). The iproute2
tool and the kernel do not validate or filter the multicast addresses
when adding them to the multicast list. Thus, when synchronizing this
list with an invalid entry, the action will be aborted with an error
since the fm10k driver currently validates the list. Consequently,
multicast entries beyond the invalid one will not be processed and
communicated with the switch via the mailbox. This change makes it so
that invalid addresses will simply be skipped and allows synchronizing
the full list to proceed.

We need to delete from offload the device externally learnded fdbs when any
one of these events happen:
1) Bridge ages out fdb. (When bridge is doing ageing vs. device doing
ageing. If device is doing ageing, it would send SWITCHDEV_FDB_DEL
directly).
2) STP state change flushes fdbs on port.
3) User uses sysfs interface to flush fdbs from bridge or bridge port:
echo 1 >/sys/class/net/BR_DEV/bridge/flush
echo 1 >/sys/class/net/BR_PORT/brport/flush
4) Offload driver send event SWITCHDEV_FDB_DEL to delete fdb entry.
For rocker, we can now get called to delete fdb entry in wait and nowait
contexts, so set NOWAIT flag when deleting fdb entry.

One of the items removed from the rocker driver in the Spring Cleanup patch
series was the ability to mark processing in the driver as "no wait" for
those contexts where we cannot sleep. Turns out, we have "no wait"
contexts where we want to program the device. So re-add the
ROCKER_OP_FLAG_NOWAIT flag to mark such processes, and propagate flags to
mem allocator and to the device cmd executor. With NOWAIT, mem allocs are
GFP_ATOMIC and device cmds are queued to the device, but the driver will
not wait (sleep) for the response back from the device.
My bad for removing NOWAIT support in the first place; I thought we could
swing non-sleep contexts to process context using a work queue, for
example, but there is push-back to keep processing in original context.

rocker->neigh_tbl_next_index is used to generate unique indices for neigh
entries programmed into the device. The way new indices were generated was
racy with the new prepare-commit transaction model. A simple fix here
removes the race. The race was with two processes getting the same index,
one process using prepare-commit, the other not:
Proc A Proc B
PREPARE phase
get neigh_tbl_next_index
NONE phase
get neigh_tbl_next_index
neigh_tbl_next_index++
COMMIT phase
neigh_tbl_next_index++
Both A and B got the same index. The fix is to store and increment
neigh_tbl_next_index in the PREPARE (or NONE) phase and use value in COMMIT
phase:
Proc A Proc B
PREPARE phase
get neigh_tbl_next_index
neigh_tbl_next_index++
NONE phase
get neigh_tbl_next_index
neigh_tbl_next_index++
COMMIT phase
// use value stashed in PREPARE phase

The bus interface functions txctl and rxctl may be used while the device
can not be accessed, eg. upon driver .remove() callback. This patch will
immediately return -EIO when this is the case which speeds up the module
unload.

The .get_station() cfg80211 callback is used in several scenarios. In
managed mode it can obtain information about the access-point and its
BSS parameters. In managed mode it can also obtain information about
TDLS peers. In AP mode it can obtain information about connected
clients.

Switch from using semi hard coded interface combinations. This makes
it easier to announce what the firmware actually supports. This fixes
the case where brcmfmac announces p2p but the firmware doesn't
support it.

We expect EEPROM per-rate power table to be filled with
s6 values and warn user if values are invalid. However,
there appear to be devices which don't have this section
of EEPROM initialized. In such case we should ignore
the values and leave the driver power tables set to zero.
Note that vendor driver doesn't care about this case but
mt76x2 skips 0xff per value. We take mt76x2's approach.

Some time ago the function debugfs_create_devm_seqfile() was
introduced in debugfs. The caller simply needs to provide a
device pointer and read function. The function brcmf_debugfs_add_entry()
is now simply a wrapper only doing the work for CONFIG_BRCMDBG.
