Hello Johannes and all, Here are several RFC patches providing simple high-level controls of AMSDU/AMPDU aggregation. The primary purpose of this functionality is an attempt to fill missing gaps in nl80211 interface for basic WFA certification tests. We experimented with QCA sigma-dut tool: https://github.com/qca/sigma-dut. The purpose was to cover basic HT/VHT WFA STA tests for cfg80211 driver controlled by wpa_supplicant w/o adding any vendor specific commands. Multiple WFA test parameters (e.g. STBC, NSS, SGI, LDPC) can be configured by overriding HT/VHT capabilities in wpa_supplicant and applying them on connect in cfg80211_connect callback. Others (e.g. RTS params) can be configured using iw tool or NL80211_CMD_SET_WIPHY directly. These patches implement simpe high-level switches for AMSDU/AMPDU aggregation. It would be interesting to collect comments/concerns regarding this approach. Does it make sense to enhance nl80211 in order to cover all the missing pieces required for WFA certification tests ? Or maybe it makes sense to use NL80211_TESTMODE subcommands for this kind of testing. The summary of changes is as follows: - nl80211/cfg80211: new wiphy flags and minimal set_wiphy/get_wiphy changes - iw: new phy subcommands to enable/disable aggregation - qtnfmac: minimal driver example - get/set aggregation Regards, Sergey kernel: drivers/net/wireless/quantenna/qtnfmac/cfg80211.c | 2 + drivers/net/wireless/quantenna/qtnfmac/commands.c | 17 ++++++++++++ drivers/net/wireless/quantenna/qtnfmac/core.h | 2 + drivers/net/wireless/quantenna/qtnfmac/qlink.h | 7 ++++ include/net/cfg80211.h | 7 ++++ include/uapi/linux/nl80211.h | 6 ++++ net/wireless/core.c | 3 ++ net/wireless/nl80211.c | 31 ++++++++++++++++++++++ 9 files changed, 76 insertions(+), 1 deletion(-) iw: nl80211.h | 6 ++++++ phy.c | 60 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 2 files changed, 66 insertions(+)
