Values in enum mlx5e_rq_flag are used as bit indixes.
Intention was to use them with no BIT(i) wrapping.
No functional bug fix here, as the same (shifted)flag bit
is used for all set, test, and clear operations.

The buffers mapping of the Multi-Packet WQEs (of Striding RQ)
is done via UMR posts, one UMR WQE per an RX MPWQE.
A single MPWQE is capable of serving many incoming packets,
usually larger than the budget of a single napi cycle.
Hence, posting a single UMR WQE per napi cycle (and handling its
completion in the next cycle) works fine in many common cases,
but not always.
When an XDP program is loaded, every MPWQE is capable of serving less
packets, to satisfy the packet-per-page requirement.
Thus, for the same number of packets more MPWQEs (and UMR posts)
are needed (twice as much for the default MTU), giving less latency
room for the UMR completions.
In this patch, we add support for multiple outstanding UMR posts,
to allow faster gap closure between consuming MPWQEs and reposting
them back into the WQ.
For better SW and HW locality, we combine the UMR posts in bulks of
(at least) two.
This is expected to improve packet rate in high CPU scale.
Performance test:
As expected, huge improvement in large-scale (48 cores).

The VSC8514 PHY is a 4-ports PHY that is 10/100/1000BASE-T, 100BASE-FX,
1000BASE-X, can communicate with the MAC via QSGMII.
The MAC interface protocol for each port within QSGMII can
be either 1000BASE-X or SGMII, if the QSGMII MAC that the VSC8514 is
connecting to supports this functionality.
VSC8514 also supports SGMII MAC-side autonegotiation on each individual
port, downshifting, can set the blinking pattern of each of its 4 LEDs,
SyncE, 1000BASE-T Ring Resiliency as well as HP Auto-MDIX detection.
This adds support for 10BASE-T, 100BASE-TX, and 1000BASE-T,
QSGMII link with the MAC, downshifting, HP Auto-MDIX detection
and blinking pattern for its 4 LEDs.
The GPIO register bank is a set of registers that are common to all PHYs
in the package. So any modification in any register of this bank affects
all PHYs of the package.
If the PHYs haven't been reset before booting the Linux kernel and were
configured to use interrupts for e.g. link status updates, it is
required to clear the interrupts mask register of all PHYs before being
able to use interrupts with any PHY. The first PHY of the package that
will be init will take care of clearing all PHYs interrupts mask
registers. Thus, we need to keep track of the init sequence in the
package, if it's already been done or if it's to be done.
Most of the init sequence of a PHY of the package is common to all PHYs
in the package, thus we use the SMI broadcast feature which enables us
to propagate a write in one register of one PHY to all PHYs in the same
package.

The default m88e151x LED configuration is 0x1177, used LED[0]
for 1000M link, LED[1] for 100M link, and LED[2] for active.
But for some boards, which use LED[0] for link, and LED[1] for
active, prefer to be 0x1040. To be compatible with this case,
this patch defines a new dev_flag, and set it before connect

The code path for Macs goes through bcm_apple_get_resources(), which
skips over the code that sets up the regulator supplies. As a result,
the call to regulator_bulk_enable() / regulator_bulk_disable() results
in a NULL pointer dereference.
This was reported on the kernel.org Bugzilla, bug 202963.
Unbreak Broadcom Bluetooth support on Intel Macs by checking if the
supplies were set up before enabling or disabling them.
The same does not need to be done for the clocks, as the common clock
framework API checks for NULL pointers.

The BCM43341B has the default MAC address 43:34:1B:00:1F:AC if none
is given. This address was found when enabling Bluetooth on multiple
Intel Edison modules. It also contains the sequence 43341B, the name
the chip identifies itself as. Using the same BD_ADDR is problematic
when having multiple Intel Edison modules in each others range.
The default address also has the LAA (locally administered address)
bit set which prevents a BNEP device from being created, needed for
BT tethering.
Add this to the list of black listed default MAC addresses and let
the user configure a valid one using f.i.

This also fixes crashes observed on platforms with ROME controllers
that are instantiated through ldisc and not as serdev clients. The
crashes are caused by NULL pointer dereferentiations, which stem from
the driver's assumption that a QCA HCI device is always associated with
a serdev device.

This adds the support of enabling MT7663S and MT7668S SDIO-based
Bluetooth function.
There are quite many differences between MT766[3,8]S and standard
Bluetooth SDIO devices such as Type-A and Type-B devices. For example,
MT766[3,8]S have its own SDIO registers layout, definition, SDIO packet
format, and the specific flow should be programmed on them to complete
the device initialization and low power control and so on.
Currently, there are many independent programming sequences from the
transport which are exactly the same as the ones in btusb.c about MediaTek
support [1] and btmtkuart.c. We can try to split the transport independent
Bluetooth setups on the advance, place them into the common files and allow
varous transport drivers to reuse them in the future.

Use the new ingress pool that was added in the previous patch for
control packets (e.g., STP, LACP) that are trapped to the CPU.
The previous management pool is no longer necessary and therefore its
size is set to 0.
The maximum quota for traffic towards the CPU is increased to 50% of the
free space in the new ingress pool and therefore the reserved space is
reduced by half, to 10KB - in both the shared and headroom buffer. This
allows for more efficient utilization of the shared buffer as reserved
space cannot be used for other purposes.

Add extack to shared buffer set operations, so that meaningful error
messages could be propagated to the user.

stmmac_check_ether_addr() checks the MAC address and assigns one in
driver open(). In many cases when we create slave netdevice, the dev
addr is inherited from master but the master dev addr maybe NULL at
that time, so move this call to driver probe so that address is
always valid.

git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux into mlx5-next
Linux 5.1-rc1
We forgot to reset the branch last merge window thus mlx5-next is outdated
and still based on 5.0-rc2. This merge commit is needed to sync mlx5-next
branch with 5.1-rc1.

Pull MIPS fixes from Paul Burton:
"A couple more MIPS fixes:
- Fix indirect syscall tracing & seccomp filtering for big endian
MIPS64 kernels, which previously loaded the syscall number
incorrectly & would always use zero.
- Fix performance counter IRQ setup for Atheros/ath79 SoCs, allowing
perf to function on those systems.
And not really a fix, but a useful addition:
- Add a Broadcom mailing list to the MAINTAINERS entry for BMIPS
systems to allow relevant engineers to track patch submissions"

The RTF_ADDRCONF flag filters out routes added by RA's in determining
which routes can be appended to an existing one to create a multipath
route. Restore the flag check and add a comment to document the RA piece.

After commit c7a1ce397ada ("ipv6: Change addrconf_f6i_alloc to use
ip6_route_info_create"), the gateway is no longer filled in for fib6_nh
structs in a prefix route. Accordingly, the RTF_ADDRCONF flag check can
be dropped from the 'rt6_qualify_for_ecmp'.
Further, RTF_DYNAMIC is only set in rt6_info instances, so it can be
removed from the check as well.
This reduces rt6_qualify_for_ecmp and the mlxsw version to just checking
if the nexthop has a gateway which is the real indication of whether
entries can be coalesced into a multipath route.
