Subject: [PATCH] net/mlx5: Fix io_eq_size and event_eq_size params validation
io_eq_size and event_eq_size params are of param type
DEVLINK_PARAM_TYPE_U32. But, the validation callback is addressing them
as DEVLINK_PARAM_TYPE_U16.
This cause mismatch in validation in big-endian systems, in which
values in range were rejected while 268500991 was accepted.
Fix it by checking the U32 value in the validation callback.
Fixes: 0844fa5f7b89 ("net/mlx5: Let user configure io_eq_size param")
