I never get 1/3 on the linux-wpan mailinglist, I don't see them also on
[0]. Maybe there is something wrong at your mail configuration? I guess
the mail is simple too big. Don't know actually what's the size limit
is...

btw: I see the mail on my other mail account (gmail one, please use
aar@xxxxxxxxxxxxxx) that you use the old "db" values - we switched to
mbm which is simple 3 dbm == 300 dbm.

This allows fine granularity dbm value -> 802.15.4 spec describes it as
signed integer, but e.g. at86rf230 also support 1.7 dbm stuff.

E.g.

ca8210_hw->phy->transmit_power = 8;

whould be:

ca8210_hw->phy->transmit_power = 800;

See [1]. Please also check on which seems that this is missing:

lp->hw->phy->supported.cca_ed_levels = at86rf23x_ed_levels;
lp->hw->phy->supported.cca_ed_levels_size = ARRAY_SIZE(at86rf23x_ed_levels);

the same for tx_powers and tx_powers_size if you support set_tx_power.
Also begin please with the highest db value at array index [0].
