Didn't checkpatch warn about this? thanks, greg k-h
Dear Kernel maintainers, First of all, thank you for spending your precious time for reviewing my changes, and also sorry for my mistakes in previous patchsets. Let me propose series of CLs for adding PMSR support in the mac80211_hwsim. PMSR (peer measurement) is generalized measurement between STAs, and currently FTM (fine time measurement or flight time measurement) is the one and only measurement. FTM measures the RTT (round trip time) and FTM can be used to measure distances between two STAs. RTT is often referred as 'measuring distance' as well. Kernel had already defined protocols for PMSR in the include/uapi/linux/nl80211.h and relevant parsing/sending code are in the net/wireless/pmsr.c, but they are only used in intel's iwlwifi driver. CLs are tested with iw tool on Virtual Android device (a.k.a. Cuttlefish). Hope this explains my CLs. Many Thanks, -- 2.39.0.246.g2a6d74b583-goog V6 -> V7: Split 'mac80211_hwsim: handle FTM requests with virtio' with three pieces V5 -> V6: Added per CL change history. V4 -> V5: Fixed style V3 -> V4: Added detailed explanation to cover letter and per CL commit messages, includes explanation of PMSR and FTM. Also fixed memory leak.
