# The wireless driver madness:
#
# - Some drivers want everything to be configured before bringing the interface up
# - Some drivers want everything to be configured after bringing the interface up
# - Some drivers want some parameters before, other parameters after bringing the interface up
#
# So, we try to set every parameter when the interface is still down,
# and remember which ones failed to be configured properly.
# If some failed, we bring the interface up, and try the failed ones again.
