Detailed Description

Test to validate that Ideal rate manager properly selects TXVECTOR in scenarios where MIMO is used.

The test consider both balanced and unbalanced MIMO settings, and verify ideal picks the correct number of spatial streams and the correct MCS, taking into account potential diversity in AWGN channels when the number of antenna at the receiver is higher than the number of spatial streams used for the transmission.
