The hardware will aggregate packets until any of following limits hit max http://fxr.watson.org/fxr/source/dev/ral/rt2860reg.h#L782 * rt2860_txwi.flags RT2860_TX_MPDU_DSITY_SHIFT 000 == no restriction 001 == 1/4 us 010 == 1/2 us ... 111 == 16 us * rt2860_txwi.xflags RT2860_TX_BAWINSIZE_SHIFT (frame count) http://fxr.watson.org/fxr/source/dev/ral/rt2860reg.h#L93 * RT2860_MAX_LEN_CFG bit 12:13 00 == 8k bytes 01 == 16k 10 == 32k 11 == 64k At a quick look, none of them is set in current code. Also, RT2860_TX_AMPDU flag need to be set to make the h/w aggregate packets. How is ampdu working on ral(4)? I cannot test because I do not have any ral(4) nic (only have run(4) nics).
