Donenfeld and Roopa Prabhu. 8) Fix mpls ether type detection in nfp, from Pieter Jansen van Vuuren. 9) More bpfilter build fixes/adjustments from Masahiro Yamada. 10) Fix XDP_{TX,REDIRECT} flushing in various drivers, from Jesper Dangaard Brouer. 11) fib_tests.sh file permissions were broken, from Shuah Khan. 12) Make sure BH/preemption is disabled in data path of mac80211, from Denis Kenzior. 13) Don't ignore nla_parse_nested() return values in nl80211, from Johannes berg. 14) Properly account sock objects ot kmemcg, from Shakeel Butt. 15) Adjustments to setting bpf program permissions to read-only, from Daniel Borkmann. 16) TCP Fast Open key endianness was broken, it always took on the host endiannness.
