0 Revision notes
R3: Add header for Revision notes (clause 0)
Add header for MAC (clause 6) and three items to be covered by MAC adhoc.
r4: Not adopted as a task group revision.
r5: Added resolvable LTFs text as motioned (10/251r2 motion #1)
Added numerology from 11-10-0070r5 excluding number of MU users (10/252r2 motion #3)

Only equal modulation on streams (10/251r3 motion #7)
r7 Deleted equal modulation requirement (motion failed). Corrected Figure 1. Task group
discussion on Nss in section 3.4.
r8 All occurances of Nss changed to Nsts in section 3.4
r9 Added same modulation and coding for SU transmission (10/251r4 motion #12)
r10 Added GroupID and Nsts fields to VHT-SIG-A (10/518r2 motion #1)

Defined Subcarrier parameters (10/518r2 motion #3)
Added SU MCS table (10/518r2 motion #4)
Defined number of L-LTFs (10/518r2 motion #5)
Defined P Matrix for up to 4x4 and 8x8 (10/518r2 motion #6)
Defined P Matrix for 6x6 (10/518r2 motion #7)
Defined 80 MHz tone allocation (10/518r2 motion #8)
r11 Added 160 MHz requirements R3.1.1.A-C (10/518r3 motion #11)
Added primary channel selection requirement R5.C (10/518r3 motion #13)
Added smoothing bit exclusion requirement (10/518r3 motion #14)
Added text to describe use of zero for Group ID (10/518r3 motion #16) Added R3.4.E for same
MCS across streams for MU (10/518r3 motion #17)
Added 1 bit for STBC (10/518r3 motion #18)
r12 Executed motions from 10/0714r3.
r13 Corrections to r12. Executed motions from July 2010, TGac PM2 session (report 10/0714r5)
r14 Executed motions from September 2010 Wednesday TGac session (report 10/1016r3).
r15 Corrected Max MPDU size. Executed motions from September 2010 Thursday PM1 TGac session
(report 10/1016r4)
r16 Motions from the November 2010 Monday PM2 session (report 10/1214r3)
r17 Motions from the November 2010 Wednesday AM1 session (report 10/1214r5)
r18 Motions from the November 2010 Thursday PM1 session (report 10/1214r7)
r19 Speculative edits based on pre-motions that passed in the Monday and Tuesday ad-hoc sessions
January 2011.
r20 Speculative edits for pre-motions from COEX ad-hoc.
r21 Accommodate edits to motions during the TG session (report 11/0011r4)
