#944: ToS bits are incorrectly mapped to IEEE 802.11e QoS in v0.9.2

ieee80211_output.c incorrectly maps ToS bits to IEEE 802.11e QoS. The
"switch ((ip->tos) & 0xFC)" statement does the mapping. It looks at the
DSCP bits in the ToS byte to assign the correct QoS.
The ToS bits which map to 802.iie access class voice (AC_VO) are 0xc0,
0xc8, and 0xe0.
The ToS bits which map to 802.iie access class video (AC_VI) are 0x28 and
0x80.
The ToS bits which map to 802.iie access class best effort (AC_BE) are
0x00 and 0x60.
The ToS bits which map to 802.iie access class background (AC_BK) are 0x08
and 0x40.
The patch below implements the correct ToS to QoS mapping.
