Split 6G band into 8 sub-bands where indexes are from 0 to 7, i.e. RTW89_CH_6G_BAND_IDX[0-7]. Then, decide subband by both band and channel instead of just channel because conflicts between 5G channels and 6G channels. Moreover, add default case to the existing use of switch (subband).

2022-02-14brcmfmac: Add BCM43454/6 supportZhao, Jiaqing4-1/+6
BCM43454/6 is a variant of BCM4345 which is exactly identical to BCM4345/6, except the chip id is 0xa9be. This patch adds support for BCM43454/6 by handing it in the same way as BCM4345. Note: when loading some specific version of BCM4345 firmware, the chip id may become 0x4345. This is an expected behavior, and it will restore to 0xa9be after power cycle.

2022-02-11Merge branch 'ipv6-loopback'David S. Miller5-72/+64
Eric Dumazet says: ==================== ipv6: remove addrconf reliance on loopback Second patch in this series removes IPv6 requirement about the netns loopback device being the last device being dismantled. This was needed because rt6_uncached_list_flush_dev() and ip6_dst_ifdown() had to switch dst dev to a known device (loopback). Instead of loopback, we can use the (hidden) blackhole_netdev which is also always there. This will allow future simplfications of netdev_run_to() and other parts of the stack like default_device_exit_batch(). Last two patches are optimizations for both IP families. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

2022-02-11ipv6: give an IPv6 dev to blackhole_netdevEric Dumazet2-59/+40
IPv6 addrconf notifiers wants the loopback device to be the last device being dismantled at netns deletion. This caused many limitations and work arounds. Back in linux-5.3, Mahesh added a per host blackhole_netdev that can be used whenever we need to make sure objects no longer refer to a disappearing device. If we attach to blackhole_netdev an ip6_ptr (allocate an idev), then we can use this special device (which is never freed) in place of the loopback_dev (which can be freed). This will permit improvements in netdev_run_todo() and other parts of the stack where had steps to make sure loopback_dev was the last device to disappear.

The mv88e6352, mv88e6240 and mv88e6176 have a serdes interface. This patch allows to configure the output swing to a desired value in the phy-handle of the port. The value which is peak to peak has to be specified in microvolts. As the chips only supports eight dedicated values we return EINVAL if the value in the DTS does not match one of these values.

2022-02-11dt-bindings: phy: Add `tx-p2p-microvolt` property bindingMarek Behún1-0/+103
Common PHYs and network PCSes often have the possibility to specify peak-to-peak voltage on the differential pair - the default voltage sometimes needs to be changed for a particular board. Add properties `tx-p2p-microvolt` and `tx-p2p-microvolt-names` for this purpose. The second property is needed to specify the mode for the corresponding voltage in the `tx-p2p-microvolt` property, if the voltage is to be used only for speficic mode. More voltage-mode pairs can be specified. Example usage with only one voltage (it will be used for all supported PHY modes, the `tx-p2p-microvolt-names` property is not needed in this case): tx-p2p-microvolt = <915000>; Example usage with voltages for multiple modes: tx-p2p-microvolt = <915000>, <1100000>, <1200000>; tx-p2p-microvolt-names = "2500base-x", "usb", "pcie"; Add these properties into a separate file phy/transmit-amplitude.yaml, which should be referenced by any binding that uses it.

2022-02-11ipv6: Reject routes configurations that specify dsfield (tos)Guillaume Nault2-0/+19
The ->rtm_tos option is normally used to route packets based on both the destination address and the DS field. However it's ignored for IPv6 routes. Setting ->rtm_tos for IPv6 is thus invalid as the route is going to work only on the destination address anyway, so it won't behave as specified.
