** Description changed:
[Impact]
The expected to fail 'raw gso min size - 1' test in psock_snd.sh is always
failing with:
raw gso min size - 1 (expected to fail)
tx: 1524
rx: 1472
OK
This is because after commit 7c6d2ec ("net: be more gentle about silly
gso requests coming from user"), we relaxed the min gso_size check in
virtio_net_hdr_to_skb().
So when a packet which is smaller then the gso_size,
GSO for this packet will not be set, the packet will be
send/recv successfully.
[Fix]
* cfba3fb68960b4 selftests/net: remove min gso test in packet_snd
- This patch can be cherry-picked into affected kernels.
+ This patch can be cherry-picked into all affected kernels.
+ I will skip those 5.8 variants, as the current cycle (2021-09-06) might be
the last cycle for them.
[Test]
Run this psock_snd.sh script, this test will no longer exist and the script
can proceed to the next test.
- [Impact]
+ [Where problems could occur]
+ Removing this broken test should not have any negative impact to our tests.

This failure is similar to bug 1884234, however, this test didn't fail
on ADT with focal/linux before 5.4.0-44.48.
