stable inclusion
from stable-v5.10.180
commit 50440cdb0b4799ddb6b56b41cee7e92443544c76
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I8DDFN

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=50440cdb0b4799ddb6b56b41cee7e92443544c76



--------------------------------

[ Upstream commit 3e358ea8 ]

Commit cited in "fixes" tag added bulk support for flow counters but it
didn't account that's also possible to query a counter using a non-base id
if the counter was allocated as bulk.

When a user performs a query, validate the flow counter id given in the
mailbox is inside the valid range taking bulk value into account.

Fixes: 208d70f5 ("IB/mlx5: Support flow counters offset for bulk counters")
