With newer VHT implementations, it's necessary to look at the HT operation's CCFS2 field to identify the actual bandwidth used. Signed-off-by:Johannes Berg <johannes.berg@intel.com>

Johannes Berg authored
Depending on whether or not rate control supports selecting rates depending on the bandwidth, we can use VHT extended NSS support. In essence, this is dot11VHTExtendedNSSBWCapable from the spec, since depending on that we'll need to parse the bandwidth. If needed, also set/clear the VHT Capability Element bit for this capability so that we don't advertise it erroneously or don't advertise it when we actually use it. Signed-off-by: -

IEEE 802.11-2016 extended the VHT capability fields to allow indicating the number of spatial streams depending on the actually used bandwidth, add support for decoding this. Signed-off-by: -

The defines of IEEE80211_HE_OPERATION_VHT_OPER_INFO and IEEE80211_HE_OPERATION_MULTI_BSSID_AP have leading zeroes that makes the number look like it is bigger than 32 bit. This is misleading, remove it. Signed-off-by:

Not all SFPs implement the registers containing sensor limits and alarms. Luckily, there is a bit indicating if they are implemented or not. Add checking for this bit, when deciding if the hwmon attributes should be visible. Fixes: 1323061a ("net: phy: sfp: Add HWMON support for module sensors") Signed-off-by:

Recent refactoring of add_metainfo() caused use_all_metadata() to add metainfo to ife action metalist without taking reference to module. This causes warning in module_put called from ife action cleanup function. Implement add_metainfo_and_get_ops() function that returns with reference to module taken if metainfo was added successfully, and call it from use_all_metadata(), instead of calling __add_metainfo() directly.
