[PATCH bluetooth-next 0/8] mac802154: several cleanups

[PATCH bluetooth-next 0/8] mac802154: several cleanups

[Alexander Aring]

Hi,

this patch series contains various cleanups for mac802154 header. Also
I cleanup a little bit the comments for several structs and flag
definitions. This also prepares for handling a API documentation
generation via docbook. The flags are enums now which is similar like
mac80211 handling.

- Alex

[PATCH bluetooth-next 1/8] mac802154: remove unneeded vif struct

[Alexander Aring]

This patch removes the virtual interface structure from sub if data
struct, because it isn't used anywhere. This structure could be useful
for give per interface information at softmac driver layer. Nevertheless
there exist no use case currently and it contains the interface type
information currently. This information is also stored inside wpan dev
which is now used to check on the wpan dev interface type.

[PATCH bluetooth-next 2/8] mac802154: cleanup address filtering flags

[Alexander Aring]

This patch changes the address filtering flags to enums and setting the
flag values with the BIT macro. Additional this patch changes the
commenting style for matching usual kernel style.

[PATCH bluetooth-next 3/8] mac802154: remove aack hw flag

[Alexander Aring]

This patch removes the hardware auto acknowdledge flag which indicates
that the transceiver supports this handling. This flag is never
evaluated inside mac802154 and all transceivers should support this
handling by default per hardware.
