# If the stanza bond-give-a-chance is set for a slave interface,

# This stanza is designed to workaround a bug in wpa_supplicant, when used with bonding :

# wpa_supplicant expect wifi authentication packets on the bond interface, but also send wifi authentication packets on the bond interface.
# If the active interface is not the wifi interface at the time wpa_supplicant try to authenticate, the wifi AP won't receive anything, causing the authentication to fail.

# In order for the wifi authentication to succeed, one need to give a chance to the wifi interface to send authentication packets.
# "bond-give-a-chance 10" will set the wifi interface as the primary interface for 10 seconds, then restore the previous primary interface.
# This is supposed to be enought to give a chance to wifi to authenticate properly.
