net: dsa: microchip: move ksz_dev_ops to ksz_common.c This patch move the ksz_dev_ops from individual files to ksz_common.c. And the dev_ops is assigned to ksz_device based on the switch detect. This reduces the redundant function and allows to reuse the functionality for LAN937x which has similar register set.

net: dsa: microchip: add support for credit based shaper KSZ9477, KSZ9567, KSZ9563, KSZ8563 and LAN937x supports Credit based shaper. To differentiate the chip supporting cbs, tc_cbs_supported flag is introduced in ksz_chip_data. And KSZ series has 16bit Credit increment registers whereas LAN937x has 24bit register. The value to be programmed in the credit increment is determined using the successive multiplication method to convert decimal fraction to hexadecimal fraction. For example: if idleslope is 10000 and sendslope is -90000, then bandwidth is 10000 - (-90000) = 100000. The 10% bandwidth of 100Mbps means 10/100 = 0.1(decimal). This value has to be converted to hexa. 1) 0.1 * 16 = 1.6 --> fraction 0.6 Carry = 1 (MSB) 2) 0.6 * 16 = 9.6 --> fraction 0.6 Carry = 9 3) 0.6 * 16 = 9.6 --> fraction 0.6 Carry = 9 4) 0.6 * 16 = 9.6 --> fraction 0.6 Carry = 9 5) 0.6 * 16 = 9.6 --> fraction 0.6 Carry = 9 6) 0.6 * 16 = 9.6 --> fraction 0.6 Carry = 9 (LSB) Now 0.1(decimal) becomes 0.199999(Hex). If it is LAN937x, 24 bit value will be programmed to Credit Inc register, 0x199999. For others 16 bit value will be prgrammed, 0x1999.

net: dsa: microchip: Enable HSR offloading for KSZ9477 This patch adds functions for providing in KSZ9477 switch HSR (High-availability Seamless Redundancy) hardware offloading. According to AN3474 application note following features are provided: - TX packet duplication from host to switch (NETIF_F_HW_HSR_DUP) - RX packet duplication discarding - Prevention of packet loop For last two ones - there is a probability that some packets will not be filtered in HW (in some special cases - described in AN3474). Hence, the HSR core code shall be used to discard those not caught frames. Moreover, some switch registers adjustments are required - like setting MAC address of HSR network interface. Additionally, the KSZ9477 switch has been configured to forward frames between HSR ports (e.g. 1,2) members to provide support for NETIF_F_HW_HSR_FWD flag. Join and leave functions are written in a way, that are executed with single port - i.e. configuration is NOT done only when second HSR port is configured.

net: dsa: microchip: Add partial ACL support for ksz9477 switches This patch adds partial Access Control List (ACL) support for the ksz9477 family of switches. ACLs enable filtering of incoming layer 2 MAC, layer 3 IP, and layer 4 TCP/UDP packets on each port. They provide additional capabilities for filtering routed network protocols and can take precedence over other forwarding functions. ACLs can filter ingress traffic based on header fields such as source/destination MAC address, EtherType, IPv4 address, IPv4 protocol, UDP/TCP ports, and TCP flags. The ACL is an ordered list of up to 16 access control rules programmed into the ACL Table. Each entry specifies a set of matching conditions and action rules for controlling packet forwarding and priority. The ACL also implements a count function, generating an interrupt instead of a forwarding action. It can be used as a watchdog timer or an event counter. The ACL consists of three parts: matching rules, action rules, and processing entries. Multiple match conditions can be either AND'ed or OR'ed together. This patch introduces support for a subset of the available ACL functionality, specifically layer 2 matching and prioritization of matched packets. For example: tc qdisc add dev lan2 clsact tc filter add dev lan2 ingress protocol 0x88f7 flower action skbedit prio 7 tc qdisc add dev lan1 clsact tc filter add dev lan1 ingress protocol 0x88f7 flower action skbedit prio 7 The hardware offloading implementation was benchmarked against a configuration without hardware offloading. This latter setup relied on a software-based Linux bridge. No noticeable differences were observed between the two configurations. Here is an example of software-based test: ip l s dev enu1u1 up ip l s dev enu1u2 up ip l s dev enu1u4 up ethtool -A enu1u1 autoneg off rx off tx off ethtool -A enu1u2 autoneg off rx off tx off ethtool -A enu1u4 autoneg off rx off tx off ip l a name br0 type bridge ip l s dev br0 up ip l s enu1u1 master br0 ip l s enu1u2 master br0 ip l s enu1u4 master br0 tc qdisc add dev enu1u1 root handle 1: ets strict 4 priomap 3 3 2 2 1 1 0 0 tc qdisc add dev enu1u4 root handle 1: ets strict 4 priomap 3 3 2 2 1 1 0 0 tc qdisc add dev enu1u2 root handle 1: ets strict 4 priomap 3 3 2 2 1 1 0 0 tc qdisc add dev enu1u1 clsact tc filter add dev enu1u1 ingress protocol ipv4 flower action skbedit prio 7 tc qdisc add dev enu1u4 clsact tc filter add dev enu1u4 ingress protocol ipv4 flower action skbedit prio 0 On a system attached to the port enu1u2 I run two iperf3 server instances: iperf3 -s -p 5210 & iperf3 -s -p 5211 & On systems attached to enu1u4 and enu1u1 I run: iperf3 -u -c 172.17.0.1 -p 5210 -b100M -l1472 -t100 and iperf3 -u -c 172.17.0.1 -p 5211 -b100M -l1472 -t100 As a result, IP traffic on port enu1u1 will be prioritized and take precedence over IP traffic on port enu1u4 Signed-off-by: Oleksij Rempel <o.rempel@pengutronix.de> Reviewed-by: Vladimir Oltean <vladimir.oltean@nxp.com> Signed-off-by: David S.
