Description (partial)

When connecting 11ac clients to the radio 2, the throughput drops especially with S4 an Linksys clients.
The issue occurs because of a check in the buffer count(number of buffers currently consumed by packets in transmit), which was set to 128. Due to this, there was some idle time causing throughput to drop.
By setting this value to 512, the system was observed to have less idle time.

Associate 11ac client (S4 and Linksys) to 11ac radio
