Hi Johannes,On our nightly test setups I found that STA->AP TCP iperf showed a regression in brcmsmac after I upgraded them from 3.18-rc5 wireless-testing (f638577)to 3.19-rc1 wireless-testing (f9e7c6c). The attached pictures are historic results showing clear drop on the last run.
Has there been any report on there since 3.19-rc1 and would you have a pointer on where to start looking. The changes in brcmsmac look trivial so looking at mac80211 now. There are some changes in minstrel and brcmsmac is using minstrel_ht rate control.
