3288 频率可以提到1.8G吗？ 在3.10里 dts里配置有1.8g选项，定频可以设置1.8G，在4.4内核里没有了只有1.6G，可以增加回来吗？

netfilter: nf_tables: deactivate anonymous set from preparation phase
8657287 
[ backport for 4.14 of c1592a8 ]

Toggle deleted anonymous sets as inactive in the next generation, so
users cannot perform any update on it. Clear the generation bitmask
in case the transaction is aborted.

The following KASAN splat shows a set element deletion for a bound
anonymous set that has been already removed in the same transaction.

selftests/bpf: Test bpf_mprog query API via libbpf and raw syscall
f9b0879 
Add a new test case which performs double query of the bpf_mprog through
libbpf API, but also via raw bpf(2) syscall. This is testing to gather
first the count and then in a subsequent probe the full information with
the program array without clearing passed structs in between.
