Tim Harvey 29ca3b3175 net: thunderx: use proper interface type for RGMII
The configuration of the OCTEONTX XCV_DLL_CTL register via
xcv_init_hw() is such that the RGMII RX delay is bypassed
leaving the RGMII TX delay enabled in the MAC:

	/* Configure DLL - enable or bypass
	 * TX no bypass, RX bypass
	 */
	cfg = readq_relaxed(xcv->reg_base + XCV_DLL_CTL);
	cfg &= ~0xFF03;
	cfg |= CLKRX_BYP;
	writeq_relaxed(cfg, xcv->reg_base + XCV_DLL_CTL);

This would coorespond to a interface type of PHY_INTERFACE_MODE_RGMII_RXID
and not PHY_INTERFACE_MODE_RGMII.

Fixing this allows RGMII PHY drivers to do the right thing (enable
RX delay in the PHY) instead of erroneously enabling both delays in the
PHY.

Vadim Pasternak 36844c855b mlxsw: core: Add validation of hardware device types for MGPIR register
When reading the number of gearboxes from the hardware, the driver does
not validate the returned 'device type' field. The driver can therefore
wrongly assume that the queried devices are gearboxes.

On Spectrum-3 systems that support different types of devices, this can
prevent the driver from loading, as it will try to query the
temperature sensors from devices which it assumes are gearboxes and in
fact are not.

For example:
[  218.129230] mlxsw_minimal 2-0048: Reg cmd access status failed (status=7(bad parameter))
[  218.138282] mlxsw_minimal 2-0048: Reg cmd access failed (reg_id=900a(mtmp),type=write)
[  218.147131] mlxsw_minimal 2-0048: Failed to setup temp sensor number 256
[  218.534480] mlxsw_minimal 2-0048: Fail to register core bus
[  218.540714] mlxsw_minimal: probe of 2-0048 failed with error -5

Fix this by validating the 'device type' field.

Ido Schimmel 490f0542a7 mlxsw: spectrum_router: Clear offload indication from IPv6 nexthops on abort
Unlike IPv4, in IPv6 there is no unique structure to represent the
nexthop and both the route and nexthop information are squashed to the
same structure ('struct fib6_info'). In order to improve resource
utilization the driver consolidates identical nexthop groups to the same
internal representation of a nexthop group.

Therefore, when the offload indication of a nexthop changes, the driver
needs to iterate over all the linked fib6_info and toggle their offload
flag accordingly.

During abort, all the routes are removed from the device and unlinked
from their nexthop group. The offload indication is cleared just before
the group is destroyed, but by that time no fib6_info is linked to the
group and the offload indication remains set.

Fix this by clearing the offload indication just before dropping the
reference from the nexthop.

Madalin Bucur 73a21fa817 dpaa_eth: support all modes with rate adapting PHYs
Stop removing modes that are not supported on the system interface
when the connected PHY is capable of rate adaptation. This addresses
an issue with the LS1046ARDB board 10G interface no longer working
with an 1G link partner after autonegotiation support was added
for the Aquantia PHY on board in

commit 09c4c57f7b ("net: phy: aquantia: add support for auto-negotiation configuration")

Before this commit the values advertised by the PHY were not
influenced by the dpaa_eth driver removal of system-side unsupported
modes as the aqr_config_aneg() was basically a no-op. After this
commit, the modes removed by the dpaa_eth driver were no longer
advertised thus autonegotiation with 1G link partners failed.

For a cyclic work queue, when not requesting a completion per WQE,
a single CQE might indicate the completion of several WQEs.
However, in case some WQE in the batch causes an error, then an error

Florian Fainelli 263a425a48 net: systemport: Avoid RBUF stuck in Wake-on-LAN mode
After a number of suspend and resume cycles, it is possible for the RBUF
to be stuck in Wake-on-LAN mode, despite the MPD enable bit being
cleared which instructed the RBUF to exit that mode.

Avoid creating that problematic condition by clearing the RX_EN and
TX_EN bits in the UniMAC prior to disable the Magic Packet Detector
logic which is guaranteed to make the RBUF exit Wake-on-LAN mode.

in iperf3 was reduced from 950Mbps to ~900Mbps. Therefore effectively
revert the original change, just use pcie_set_readrq() now instead of

Harini Katakam f822e9c4ff net: macb: Limit maximum GEM TX length in TSO
GEM_MAX_TX_LEN currently resolves to 0x3FF8 for any IP version supporting
TSO with full 14bits of length field in payload descriptor. But an IP
errata causes false amba_error (bit 6 of ISR) when length in payload
descriptors is specified above 16387. The error occurs because the DMA
falsely concludes that there is not enough space in SRAM for incoming
payload. These errors were observed continuously under stress of large
packets using iperf on a version where SRAM was 16K for each queue. This
errata will be documented shortly and affects all versions since TSO
functionality was added. Hence limit the max length to 0x3FC0 (rounded).

Vasundhara Volam d407302895 bnxt_en: Fix logic that disables Bus Master during firmware reset.
The current logic that calls pci_disable_device() in __bnxt_close_nic()
during firmware reset is flawed.  If firmware is still alive, we're
disabling the device too early, causing some firmware commands to
not reach the firmware.

Fix it by moving the logic to bnxt_reset_close().  If firmware is
in fatal condition, we call pci_disable_device() before we free
any of the rings to prevent DMA corruption of the freed rings.  If
firmware is still alive, we call pci_disable_device() after the
last firmware message has been sent.

Michael Chan 12de2eadf8 bnxt_en: Fix RDMA driver failure with SRIOV after firmware reset.
bnxt_ulp_start() needs to be called before SRIOV is re-enabled after
firmware reset.  Re-enabling SRIOV may consume all the resources and
may cause the RDMA driver to fail to get MSIX and other resources.
Fix it by calling bnxt_ulp_start() first before calling
bnxt_reenable_sriov().

We re-arrange the logic so that we call bnxt_ulp_start() and
bnxt_reenable_sriov() in proper sequence in bnxt_fw_reset_task() and
bnxt_open().  The former is the normal coordinated firmware reset sequence
and the latter is firmware reset while the function is down.  This new
logic is now more straight forward and will now fix both scenarios.

It's found that stmmac_xmit() and stmmac_resume() sometimes might
run concurrently, possibly resulting in a race condition between
mod_timer() and setup_timer(), being called by stmmac_xmit() and
stmmac_resume() respectively.

Since the resume() runs setup_timer() every time, it'd be safer to
have del_timer_sync() in the suspend() as the counterpart.

Linus Torvalds c5951e7c8e The main MIPS changes for 5.6:
- Support mremap() for the VDSO, primarily to allow CRIU to restore the
   VDSO to its checkpointed location.
 
 - Restore the MIPS32 cBPF JIT, after having reverted the enablement of
   the eBPF JIT for MIPS32 systems in the 5.5 cycle.
 
 - Improve cop0 counter synchronization behaviour whilst onlining CPUs by
   running with interrupts disabled.
 
 - Better match FPU behaviour when emulating multiply-accumulate
   instructions on pre-r6 systems that implement IEEE754-2008 style MACs.
 
 - Loongson64 kernels now build using the MIPS64r2 ISA, allowing them to
   take advantage of instructions introduced by r2.
 
 - Support for the Ingenic X1000 SoC & the really nice little CU Neo
   development board that's using it.
 
 - Support for WMAC on GARDENA Smart Gateway devices.
 
 - Lots of cleanup & refactoring of SGI IP27 (Origin 2*) support in
   preparation for introducing IP35 (Origin 3*) support.
 
 - Various Kconfig & Makefile cleanups.

Andy Shevchenko dd3e7cba16 ocfs2/dlm: move BITS_TO_BYTES() to bitops.h for wider use
There are users already and will be more of BITS_TO_BYTES() macro.  Move
it to bitops.h for wider use.

In the case of ocfs2 the replacement is identical.

As for bnx2x, there are two places where floor version is used.  In the
first case to calculate the amount of structures that can fit one memory
page.  In this case obviously the ceiling variant is correct and
original code might have a potential bug, if amount of bits % 8 is not
0.  In the second case the macro is used to calculate bytes transmitted
in one microsecond.  This will work for all speeds which is multiply of
1Gbps without any change, for the rest new code will give ceiling value,
for instance 100Mbps will give 13 bytes, while old code gives 12 bytes
and the arithmetically correct one is 12.5 bytes.  Further the value is
used to setup timer threshold which in any case has its own margins due
to certain resolution.  I don't see here an issue with slightly shifting
thresholds for low speed connections, the card is supposed to utilize
highest available rate, which is usually 10Gbps.

Add to debug dump more information on the platform it was collected
from (pci func, path id).
Provide human readable reg fifo erros.

Removed static debug arrays from HSI Functions, and move them to
the hwfn.

Some structures were slightly changed (removing reserved chip id
for example) which lead to many long initializations being modified
with one parameter less during initialization. This leads to
some long diffs that don't really change anything.

The QM phase init tool can be invoked multiple times during

The logic for setting the values did not init all values, basically
assuming the runtime array was all zeroes. But if it was invoked
multiple times, nobody was zeroing it after the first time.

In this change we zero the runtime array right after using it.
