Is there a reason for skipping the selftests/netfilter tests?

eg;
https://qa-reports.linaro.org/lkft/linux-stable-rc-linux-5.10.y/build/v5.10.57-155-ged2493daa915/testrun/5442487/suite/kselftest-net/test/netfilter:nft_trans_stress.sh/details/

I have not double checked (n=1) but it looks like this patch is the
first for that test to hang on for 13 hours. The state just before I
killed the test;

ps ax --forest

I have seen a set of test cases hang so I have skipped them.

x86_64 is using NFS root file system the net and netfilter tests performing
network interfaces up and down causing network failure and system hang.

The reasons for failure are listed in this document.
