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.

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.

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.

3) User uses sysfs interface to flush fdbs from bridge or bridge port:

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

When programming the start of a periodic output, the code wrongly places
the seconds value into the "low" register and the nanoseconds into the
"high" register. Even though this is backwards, it slipped through my
testing, because the re-arming code in the interrupt service routine is
correct, and the signal does appear starting with the second edge.
This patch fixes the issue by programming the registers correctly.

The bna_rx_config struct member paused can be removed as it is never

flags also cannot have BNA_RXF_F_PAUSED value and is always zero.
So the flags member can be removed as well as bna_rxf_flags enum and

This clean-up makes bna_rxf_sm_paused state unsed and can be also removed.

Each transport object, namely TIR and TIS, must have a transport domain

The driver wrongly assumed that it is OK to use TDN=0 without explicit

The TDN will also be used for isolating different processes once user
mode Ethernet will be supported.

When NETIF_F_SG is set, each send WQE may have a different size since
each skb can have different number of fragments as of LSO header etc.
This implies that a given WQE may wrap around the send queue, i.e begin
at its end and continue at its start. While it is legal by the device spec,
we preferred a solution that avoids it - when building of current WQE is
done, if the next WQE may wrap around the send queue, fill the send queue
with NOPs WQEs till its end, so that the next WQE will begin at send queue
start.
NOP WQE for itself cannot wrap around the send queue since it is of
minimal size - 64 bytes, and all send WQEs are a multiple of that size.

was introduced during the code cleanup of commit
6b0c21cede (net: Fix p3_gelic_net sparse warnings),
which re-arranged the ordering of some of the gelic routines.
This change just moves the gelic_descr_get_status() routine up in the
ps3_gelic_net.c source file. There is no functional change.
