Detailed Description

Test OFDMA acknowledgment sequences.

Run this test with:

NS_LOG="WifiMacOfdmaTestSuite=info|prefix_time|prefix_node" ./ns3 run "test-runner --suite=wifi-mac-ofdma"

to print the list of transmitted frames only, along with the TX time and the node prefix. Replace 'info' with 'debug' if you want to print the debug messages from the test multi-user scheduler only. Replace 'info' with 'level_debug' if you want to print both the transmitted frames and the debug messages.
