[ Upstream commit 1d3c6414950badaa38002af3b5857e01a21f01e9 ]

When VLAN tag strip is changed to enable or disable, the hardware requires
the Rx ring to be in a disabled state, otherwise the feature cannot be
changed.

[ Upstream commit ac71ab7816b675f1c9614015bd87bfccb456c394 ]

Hardware requires VLAN CTAG and STAG configuration always matches. And
whether VLAN CTAG or STAG changes, the configuration needs to be changed
as well.

[ Upstream commit 68067f065ee730c7c67b361c3c81808d25d5a90b ]

Fix the issue where some Rx features cannot be changed.

When using ethtool -K to turn off rx offload, it returns error and
displays "Could not change any device features". And netdev-&gt;features
is not assigned a new value to actually configure the hardware.

<title>idpf: don't skip over ethtool tcp-data-split setting</title>

<content type='text'>
[ Upstream commit 67708158e732bf03d076fba1e3d4453fbf8292a2 ]

Disabling tcp-data-split on idpf silently fails:
  # ethtool -G $NETDEV tcp-data-split off
  # ethtool -g $NETDEV | grep 'TCP data split'
  TCP data split:        on

But it works if you also change 'tx' or 'rx':
  # ethtool -G $NETDEV tcp-data-split off tx 256
  # ethtool -g $NETDEV | grep 'TCP data split'
  TCP data split:        off

The bug is in idpf_set_ringparam, where it takes a shortcut out if the
TX and RX sizes are not changing. Fix it by checking also if the
tcp-data-split setting remains unchanged. Only then can the soft reset
be skipped.

<title>bnxt_re: avoid shift undefined behavior in bnxt_qplib_alloc_init_hwq</title>

<content type='text'>
[ Upstream commit 78cfd17142ef70599d6409cbd709d94b3da58659 ]

Undefined behavior is triggered when bnxt_qplib_alloc_init_hwq is called
with hwq_attr-&gt;aux_depth != 0 and hwq_attr-&gt;aux_stride == 0.
In that case, "roundup_pow_of_two(hwq_attr-&gt;aux_stride)" gets called.
roundup_pow_of_two is documented as undefined for 0.

Fix it in the one caller that had this combination.

The undefined behavior was detected by UBSAN:
  UBSAN: shift-out-of-bounds in ./include/linux/log2.h:57:13

[ Upstream commit cf7385cb26ac4f0ee6c7385960525ad534323252 ]

In of_modalias(), if the buffer happens to be too small even for the 1st
snprintf() call, the len parameter will become negative and str parameter
(if not NULL initially) will point beyond the buffer's end. Add the buffer
overflow check after the 1st snprintf() call and fix such check after the
strlen() call (accounting for the terminating NUL char).

[ Upstream commit c55f7ee2ec239b6afd8639c7ac06493876deb0ea ]

According to ipq5018.dtsi, the maximum supported rate by the
CPU is 1.008 GHz on the IPQ5018 platform, however the current
configuration of the PLL results in 1.2 GHz rate.

Change the 'L' value in the PLL configuration to limit the
rate to 1.008 GHz. The downstream kernel also uses the same
value [1]. Also add a comment to indicate the desired
frequency.

[ Upstream commit 07fb0a76bb757990b99fc2ab78ad7d1709cc441d ]

CONFIG_SM_GCC_8650 depends on ARM64 but it is selected by
CONFIG_SM_GPUCC_8650, which can be selected on ARM, resulting in a
Kconfig warning.
