net: atlantic: proper rss_ctrl1 (54c0) initialization This patch fixes an inconsistency between code and spec, which was found while working on the QoS implementation. When 8TCs are used, 2 is the maximum supported number of index bits. In a 4TC mode, we do support 3, but we shouldn't really use the bytes, which are intended for the 8TC mode.

net: atlantic: QoS implementation: multi-TC support This patch adds multi-TC support. PTP is automatically disabled when the user enables more than 2 TCs, otherwise traffic on TC2 won't quite work, because it's reserved for PTP.

net: atlantic: changes for multi-TC support This patch contains the following changes: * access cfg via aq_nic_get_cfg() in aq_nic_start() and aq_nic_map_skb(); * call aq_nic_get_dev() just once in aq_nic_map_skb(); * move ring allocation/deallocation out of aq_vec_alloc()/aq_vec_free(); * add the missing aq_nic_deinit() in atl_resume_common(); * rename 'tcs' field to 'tcs_max' in aq_hw_caps_s to differentiate it from the 'tcs' field in aq_nic_cfg_s, which is used for the current number of TCs; * update _TC_MAX defines to the actual number of supported TCs; * move tx_tc_mode register defines slightly higher (just to keep the order of definitions); * separate variables for TX/RX buff_size in hw_atl*_hw_qos_set(); * use AQ_HW_*_TC instead of hardcoded magic numbers; * actually use the 'ret' value in aq_mdo_add_secy(); Signed-off-by: Dmitry Bezrukov <dbezrukov@marvell.com> Co-developed-by: Mark Starovoytov <mstarovoitov@marvell.com> Signed-off-by: Mark Starovoytov <mstarovoitov@marvell.com> Signed-off-by: Igor Russkikh <irusskikh@marvell.com> Signed-off-by: David S.

net: atlantic: A2 ingress / egress hw configuration Chip generations are mostly compatible register-wise, but there are still some differences. Therefore we've made some of first generation (A1) code non-static to re-use it where possible. Some pieces are A2 specific, in which case we redefine/extend such APIs.
