Newer generation Hardware uses the slightly different port speed bit widths, so alter the existing port speed bit range to extend support to the newer generation hardware while maintaining the backward compatibility with older generation hardware. The previously reserved bits are now being used which then requires the adjustment to the BIT values, e.g.: Before: PORT_PROPERTY_0[22:21] - Reserved PORT_PROPERTY_0[26:23] - Supported Speeds After: PORT_PROPERTY_0[21] - Reserved PORT_PROPERTY_0[26:22] - Supported Speeds To make this backwards compatible, the existing BIT definitions for the port speeds are incremented by one to maintain the original position.

2021-12-20rfkill: allow to get the software rfkill stateEmmanuel Grumbach
iwlwifi needs to be able to differentiate between the software rfkill state and the hardware rfkill state. The reason for this is that iwlwifi needs to notify any change in the software rfkill state even when it doesn't own the device (which means even when the hardware rfkill is asserted). In order to be able to know the software rfkill when the host does not own the device, iwlwifi needs to be able to ask the state of the software rfkill ignoring the state of the hardware rfkill.

2021-12-20mac80211: introduce channel switch disconnect functionNathan Errera
Introduce a disconnect function that can be used when a channel switch error occurs. The channel switch can request to block the tx, and so, we need to make sure we do not send a deauth frame in this case.

2021-12-20cfg80211: simplify cfg80211_chandef_valid()Johannes Berg
There are a lot of duplicate checks in this function to check the delta between the control channel and CF1. With the addition of 320 MHz, this will become even more. Simplify the code so that the common checks are done only once for multiple bandwidths.

2021-12-20mac80211: fix FEC flag in radio tap headerP Praneesh
In mac80211, while building radiotap header IEEE80211_RADIOTAP_MCS_HAVE_FEC flag is missing when LDPC enabled from driver, hence LDPC is not updated properly in radiotap header. Fix that by adding HAVE_FEC flag while building radiotap header.

2021-12-20mac80211: use coarse boottime for airtime fairness codeFelix Fietkau
The time values used by the airtime fairness code only need to be accurate enough to cover station activity detection. Using ktime_get_coarse_boottime_ns instead of ktime_get_boottime_ns will drop the accuracy down to jiffies intervals, but at the same time saves a lot of CPU cycles in a hot path Signed-off-by: Felix Fietkau <nbd@nbd.name> Acked-by: Toke Høiland-Jørgensen <toke@redhat.com> Link: https://lore.kernel.org/r/20211217114258.14619-1-nbd@nbd.name Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2021-12-19Merge branch 'tc-action-offload'David S. Miller
Simon Horman says: ==================== allow user to offload tc action to net device Baowen Zheng says: Allow use of flow_indr_dev_register/flow_indr_dev_setup_offload to offload tc actions independent of flows. The motivation for this work is to prepare for using TC police action instances to provide hardware offload of OVS metering feature - which calls for policers that may be used by multiple flows and whose lifecycle is independent of any flows that use them. This patch includes basic changes to offload drivers to return EOPNOTSUPP if this feature is used - it is not yet supported by any driver. Tc cli command to offload and quote an action: # tc qdisc del dev $DEV ingress && sleep 1 || true # tc actions delete action police index 200 || true # tc qdisc add dev $DEV ingress # tc qdisc show dev $DEV ingress # tc actions add action police rate 100mbit burst 10000k index 200 skip_sw # tc -s -d actions list action police total acts 1 action order 0: police 0xc8 rate 100Mbit burst 10000Kb mtu 2Kb action reclassify overhead 0b linklayer ethernet ref 1 bind 0 installed 142 sec used 0 sec Action statistics: Sent 0 bytes 0 pkt (dropped 0, overlimits 0 requeues 0) backlog 0b 0p requeues 0 skip_sw in_hw in_hw_count 1 used_hw_stats delayed # tc filter add dev $DEV protocol ip parent ffff: \ flower skip_sw ip_proto tcp action police index 200 # tc -s -d filter show dev $DEV protocol ip parent ffff: filter pref 49152 flower chain 0 filter pref 49152 flower chain 0 handle 0x1 eth_type ipv4 ip_proto tcp skip_sw in_hw in_hw_count 1 action order 1: police 0xc8 rate 100Mbit burst 10000Kb mtu 2Kb action reclassify overhead 0b linklayer ethernet ref 2 bind 1 installed 300 sec used 0 sec Action statistics: Sent 0 bytes 0 pkt (dropped 0, overlimits 0 requeues 0) backlog 0b 0p requeues 0 skip_sw in_hw in_hw_count 1 used_hw_stats delayed # tc filter add dev $DEV protocol ipv6 parent ffff: \ flower skip_sw ip_proto tcp action police index 200 # tc -s -d filter show dev $DEV protocol ipv6 parent ffff: filter pref 49151 flower chain 0 filter pref 49151 flower chain 0 handle 0x1 eth_type ipv6 ip_proto tcp skip_sw in_hw in_hw_count 1 action order 1: police 0xc8 rate 100Mbit burst 10000Kb mtu 2Kb action reclassify overhead 0b linklayer ethernet ref 3 bind 2 installed 761 sec used 0 sec Action statistics: Sent 0 bytes 0 pkt (dropped 0, overlimits 0 requeues 0) backlog 0b 0p requeues 0 skip_sw in_hw in_hw_count 1 used_hw_stats delayed # tc -s -d actions list action police total acts 1 action order 0: police 0xc8 rate 100Mbit burst 10000Kb mtu 2Kb action reclassify overhead 0b linklayer ethernet ref 3 bind 2 installed 917 sec used 0 sec Action statistics: Sent 0 bytes 0 pkt (dropped 0, overlimits 0 requeues 0) backlog 0b 0p requeues 0 skip_sw in_hw in_hw_count 1 used_hw_stats delayed Changes between v7 and v8: * Rename enum offload_act_command as enum flow_offload_act_command * Add a single patch to rename exts stats update function for readability. * Fix the kernel test robot issue reported by Oliver Sang.
