Public bug reported:
There are two patches about tunable buffer sizes that are changing the
conventional behavior in our SMC code.
This change of behavior might not be expected by our clients, which could lead
to problems.
Therefore, we need to remove these two patches from v6.2 / lunar, until we can
provide an appropriate solution.
The two patches to be removed depend on each other, but don't have any
further dependencies to other code/commits.
Please remove / revert the following two patches:
0227f058aa29 net/smc: Unbind r/w buffer size from clcsock and make them tunable
77eee3251431 net/smc: Introduce a specific sysctl for TEST_LINK time
