[PATCH net-next 09/15] net/mlx5e: psp: Adjust rx_check FT size and use a drop_group

[Tariq Toukan <tariqt@nvidia.com>]

From: Cosmin Ratiu <cratiu@nvidia.com>

The rx_check ft was requesting max_fte == 2, but it created 4 entries.
While this accidentally works, it's not accurate, so change that and use
the correct number of entries. Also use an explicit drop_group for the
last match(*) drop rule.
