Background
EIFS is defined on p72 lines of D2 as follows:
EIFS=aSIFSTime +ACKTime+DIFS
EIFS should differentiate between traffic classes as follows:
EIFS=aSIFSTime +ACKTime+AIFS
[see also 01/117r1]
Without the correction, AIFS differentiation disappears after a collision

Motion
Modify text in Clause as follows:
The EIFS is derived from the SIFS and the (DIFS) AIFS and the length of time it takes to transmit an ACK Control frame at the PHY's lowest mandatory rate by the following equation:
EIFS = aSIFSTime + ACKTime+ (DIFS)AIFS
