commit c9c13ba428 upstream.
Code that iterates over all standard PCI BARs typically uses
PCI_STD_RESOURCE_END. However, that requires the unusual test
"i <= PCI_STD_RESOURCE_END" rather than something the typical
"i < PCI_STD_NUM_BARS".
Add a definition for PCI_STD_NUM_BARS and change loops to use the more
idiomatic C style to help avoid fencepost errors.

commit 894020fdd8 upstream.
Conflicts:
- Minor refractor due to code differences, Thanks to Katrin
- Introduce an compact helper in include/linux/aer
Too many 3rd part modules depend on this symbol, it can break
easily later if we drop in some other modules, so use a
function as alias. We may make is a GPL_SYMBOL later.
The AER interfaces to clear error status registers were a confusing mess:
- pci_cleanup_aer_uncorrect_error_status() cleared non-fatal errors
from the Uncorrectable Error Status register.
- pci_aer_clear_fatal_status() cleared fatal errors from the
Uncorrectable Error Status register.
- pci_cleanup_aer_error_status_regs() cleared the Root Error Status
register (for Root Ports), the Uncorrectable Error Status register,
and the Correctable Error Status register.
Rename them to make them consistent:
From To
---------------------------------------- -------------------------------
pci_cleanup_aer_uncorrect_error_status() pci_aer_clear_nonfatal_status()
pci_aer_clear_fatal_status() pci_aer_clear_fatal_status()
pci_cleanup_aer_error_status_regs() pci_aer_clear_status()
Since pci_cleanup_aer_error_status_regs() (renamed to
pci_aer_clear_status()) is only used within drivers/pci/, move the
declaration from <linux/aer.h> to drivers/pci/pci.h.

If negotiated NVSP version <= NVSP_PROTOCOL_VERSION_6, the offset may

Both rtl_work_func_t() and rtl8152_close() call napi_disable().
Since the two calls aren't protected by a lock, if the close
function starts executing before the work function, we can get into a
situation where the napi_disable() function is called twice in
succession (first by rtl8152_close(), then by set_carrier()).
In such a situation, the second call would loop indefinitely, since
rtl8152_close() doesn't call napi_enable() to clear the NAPI_STATE_SCHED
bit.
The rtl8152_close() function in turn issues a
cancel_delayed_work_sync(), and so it would wait indefinitely for the
rtl_work_func_t() to complete. Since rtl8152_close() is called by a
process holding rtnl_lock() which is requested by other processes, this
eventually leads to a system deadlock and crash.
Re-order the napi_disable() call to occur after the work function
disabling and urb cancellation calls are issued.

When receiving many or larger packets, e.g. when doing a file download,
it was observed that the read buffer size register reports up to 4 bytes
more than the current define allows in the check.
If this is the case, then no data transfer is initiated to receive the
packets (and thus to empty the buffer) which results in a stall of the
interface.
These 4 bytes are a hardware generated frame length which is prepended
to the actual frame, thus we have to respect it during our check.

On some old Firmwares, connector type value was not supported, and value
read from FW was 0. For those, driver used link mode in order to set
connector type in link_ksetting.
After FW exposed the connector type, driver translated the value to ethtool
definitions. However, as 0 is a valid value, before returning PORT_OTHER,
driver run the check of link mode in order to maintain backward
compatibility.
Cited patch added support to EXT mode. With both features (connector type
and EXT link modes) ,if connector_type read from FW is 0 and EXT mode is
set, driver mistakenly compare EXT link modes to non-EXT link mode.
Fixed that by skipping this comparison if we are in EXT mode, as connector
type value is valid in this scenario.

CONFIG_PM is defined, otherwise pm_runtime_get_sync will also be

Modifying the link settings via phylink_ethtool_ksettings_set() and
phylink_ethtool_set_pauseparam() didn't always work as intended for
PHY based setups, as calling phylink_mac_config() would result in the
unresolved configuration being committed to the MAC, rather than the
configuration with the speed and duplex setting.
This would work fine if the update caused the link to renegotiate,
but if no settings have changed, phylib won't trigger a renegotiation
cycle, and the MAC will be left incorrectly configured.
Avoid calling phylink_mac_config() unless we are using an inband mode
in phylink_ethtool_ksettings_set(), and use phy_set_asym_pause() as
introduced in 4.20 to set the PHY settings in
phylink_ethtool_set_pauseparam().

During performance testing, I found that one of my r8169 NICs suffered
a major performance loss, a 8168c model.
Running netperf's TCP_STREAM test didn't return the expected
throughput of > 900 Mb/s, but rather only about 22 Mb/s. Strange
enough, running the TCP_MAERTS and UDP_STREAM tests all returned with
throughput > 900 Mb/s, as did TCP_STREAM with the other r8169 NICs I can
test (either one of 8169s, 8168e, 8168f).
Bisecting turned up commit 93681cd7d9,
"r8169: enable HW csum and TSO" as the culprit.

XDP_TX rings should not be limited by max_num_tx_rings_p_up.
To make sure total number of TX rings never exceed MAX_TX_RINGS,
add similar check in mlx4_en_alloc_tx_queue_per_tc(), where
a new value is assigned for num_up.

The helper mlxsw_sp_ipip_dev_ul_tb_id() determines the underlay VRF of a
GRE tunnel. For a tunnel without a bound device, it uses the same VRF that
the tunnel is in. However in Linux, a GRE tunnel without a bound device
uses the main VRF as the underlay. Fix the function accordingly.
mlxsw further assumed that moving a tunnel to a different VRF could cause
conflict in local tunnel endpoint address, which cannot be offloaded.
However, the only way that an underlay could be changed by moving the
tunnel device itself is if the tunnel device does not have a bound device.
But in that case the underlay is always the main VRF, so there is no
opportunity to introduce a conflict by moving such device. Thus this check
constitutes a dead code, and can be removed, which do.

ethtool expects ETHTOOL_GRXCLSRLALL to set ethtool_rxnfc->data with the
total number of entries in the rx classifier table. Surprisingly, mlx4
is missing this part (in principle ethtool could still move forward and
try the insert).
Tested: compiled and run command:
phh13:~# ethtool -N eth1 flow-type udp4 queue 4
Added rule with ID 255
