2022-04-20net: atlantic: Implement xdp control planeTaehee Yoo
aq_xdp() is a xdp setup callback function for Atlantic driver. When XDP is attached or detached, the device will be restarted because it uses different headroom, tailroom, and page order value. If XDP enabled, it switches default page order value from 0 to 2. Because the default maximum frame size is still 2K and it needs additional area for headroom and tailroom. The total size(headroom + frame size + tailroom) is 2624. So, 1472Bytes will be always wasted for every frame. But when order-2 is used, these pages can be used 6 times with flip strategy. It means only about 106Bytes per frame will be wasted. Also, It supports xdp fragment feature. MTU can be 16K if xdp prog supports xdp fragment. If not, MTU can not exceed 2K - ETH_HLEN - ETH_FCS. And a static key is added and It will be used to call the xdp_clean handler in ->poll(). data plane implementation will be contained the followed patch.

2020-07-20net: atlantic: split rx and tx per-queue statsMark Starovoytov
This patch splits rx and tx per-queue stats. This change simplifies the follow-up introduction of PTP stats and u64_stats_update_* usage.

2020-07-20net: atlantic: make _get_sw_stats return count as return valueMark Starovoytov
This patch changes aq_vec_get_sw_stats() to return count as a return value (which was unused) instead of an out parameter. Signed-off-by: Mark Starovoytov <mstarovoitov@marvell.com> Signed-off-by: Igor Russkikh <irusskikh@marvell.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2020-05-22net: atlantic: per-TC queue statisticsMark Starovoytov
This patch adds support for per-TC queue statistics. By default (single TC), the output is the same as it used to be, e.g.: Queue[0] InPackets: 2 Queue[0] OutPackets: 8 Queue[0] Restarts: 0 Queue[0] InJumboPackets: 0 Queue[0] InLroPackets: 0 Queue[0] InErrors: 0 If several TCs are enabled, then each queue statistics line is prefixed with TC number, e.g.: TC0 Queue[0] InPackets: 6 TC0 Queue[0] OutPackets: 11 Queue numbering is end-to-end, so: TC1 Queue[4] InPackets: 0 TC1 Queue[4] OutPackets: 22 Signed-off-by: Mark Starovoytov <mstarovoitov@marvell.com> Signed-off-by: Igor Russkikh <irusskikh@marvell.com> Signed-off-by: David S.

2020-05-22net: atlantic: changes for multi-TC supportDmitry Bezrukov
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.

2018-01-16net: aquantia: Eliminate aq_nic structure abstractionIgor Russkikh
aq_nic_s was hidden in aq_nic_internal.h, that made it difficult to access nic fields and structures from other modules. This change moves aq_nic_s struct into aq_nic.h and thus makes it available to other driver modules, mainly pci module and hw related module.
