This patch adds support for dumping phy capabilities by running iwpan list,
which printout something like:
capabilities:
iftypes: node,monitor
channels:
page 0: 11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26
tx_powers: 3,2,1,0,-1,-2,-3,-4,-5,-7,-9,-12,-17
cca_ed_levels: -91,-89,-87,-85,-83,-81,-79,-77,-75,-73,-71,-69,-67,-65,-63,-61
cca_modes: 1,2,3
cca_opts: 0(cca_mode: 3),1(cca_mode: 3)
min_be: 0,1,2,3,4,5,6,7,8
max_be: 3,4,5,6,7,8
csma_backoffs: 0,1,2,3,4,5
frame_retries: -1,0,1,2,3,4,5,6,7
lbt: false
