[ath9k-devel] IPerf and Frame Aggregation and Ath9k

[Eduardo Rocha]

Hi everyone,

I wanted to evaluate the performance of frame aggregation in 802.11n 
networks. I was planning on using IPerf to measure throughputs, 
bandwidths and packet losses. How can I enable frame aggregation in ath9k?

Your help is highly appreciated.

Best regards,
Eduardo

by default its enabled in the STA mode. if you want to specifically
test aggregation
alone, you can a somewhat old package and clear SC_OP_TXAGGR/SC_OP_RXAGGR.
*another idea is to disable ht with the latest package.
*send delba from the other side to disable aggregation.

Hi,

by default AMPDU is enabled in ath9k.
rx AMSDU is supported , while not so in the tx side.
