You could use following statistic counters RT2860_TX_AGG_CNT0 to 7 https://gitorious.org/run/run/blobs/11n_rc3/dev/usb/wlan/if_runreg.h#line186 Each 32-bit little-endian read-on-clear register contains 2 16-bit counters (total 16 16-bit counters). counter at offset 0x1720 MPDU count 1 counter at offset 0x1722 MPDU count 2 ... counter at offset 0x173c MPDU count 15 counter at offset 0x173e MPDU count >= 16 These regs are identical on RT2800 and RT2700 (pci/usb). Example (see #if 0 part) https://gitorious.org/run/run/blobs/11n_rc3/dev/usb/wlan/if_run.c#line2493 You can only find out statistical numbers (total Tx counts past X sec). You cannot find out an MPDU count in a particular packet, i.e. an aggregated packet just Tx'd, unless you read the counters on each Tx.
