iwlwifi: tid_data logic move to upper layer - seq_number
The tid_data is not related to the transport layer, so move the logic that depends on it to the upper layer. This patch deals with the seq_number. Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com> Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com>
