Hi,
this patch series contains support for phy capabilities. The phy capabilities
can be used to check the setting parameters in nl802154 before we calling the
according rdev-ops to send them into SoftMAC/Driver(HardMAC) layer. This avoids
that we know before sending them to these layers that we know a "-EINVAL" before,
this can be used to check all setting parameters in one setting commands like [0].
Additional we can now dump the capabilities into userspace so users know what the
phy is supported.
The initial values for phy capabilities is that if the driver supports the according
handling then the full range of 802.15.4 is supported like csma parameters or
max frame retries. If the driver doesn't support the setting of these we assume the
802.15.4 standard values which cannot be changed. (If the phy supports that in any
way then the driver is broken and need to support that, we assume that the phy
doing 802.15.4 defaults). This case is for mac parameters. In case of that the driver
supports the according settings like CSMA/frame retries _but_ not the full range of
the 802.15.4 then the driver can overwrite this behaviour by changing the capabilities.
For phy parameters, if the driver doesn't set anything, then there is also no
possibility to change these values from userspace, this is also a lack of support
inside the driver then.
At least this patch series also includes a rework of setting/reporting
tx_powers/cca_ed_levels values.
Note: this patch series based on the ("ieee802154: Add trace events for rdev->ops") by
Guido Günther <agx@xxxxxxxxxxx>.
