I have now successfully tested the broadcom-wl driver with any usage of the last_rx field disabled on the following platforms/distributions: - openSUSE_Leap_42.2: 4.10.12-2.1.g11b3f7c - openSUSE_Leap_42.2: 4.4.57-18.3.1 - openSUSE_Leap_42.1: 4.10.12-2.1.g11b3f7c - openSUSE_Leap_42.1: 4.1.39-53.1 And, I have compile-tested it on the 42.3 kernel, so I assume this issue can be closed as WORKSFORME.
