Basic DSA driver support for lan937x and the device will be configured through SPI interface. It adds the lan937x_dev_ops in ksz_common.c file and tries to reuse the functionality of ksz9477 series switch. drivers/net/dsa/microchip/ path is already part of MAINTAINERS & the new files come under this path. Hence no update needed to the MAINTAINERS Signed-off-by:

The ksz9477 and lan937x has few difference in the static and reserved table register 0x041C. For the ksz9477 if the bit 0 is 1 - read operation and 0 - write operation. But for lan937x bit 1:0 used for selecting the read/write operation, 01 - write and 10 - read. To use ksz9477 mdb add/del and enable_stp_addr for the lan937x, masks & shifts are introduced for ksz9477 & lan937x in ksz_common.c. Then updated the function with masks & shifts based on the switch instead of hard coding it. Signed-off-by:

Documentation in .yaml format and updates to the MAINTAINERS Also 'make dt_binding_check' is passed. RGMII internal delay values for the mac is retrieved from rx-internal-delay-ps & tx-internal-delay-ps as per the feedback from v3 patch series. https://lore.kernel.org/netdev/20210802121550.gqgbipqdvp5x76ii@skbuf/ It supports only the delay value of 0ns and 2ns.

Most drivers use "skb_transport_offset(skb) + tcp_hdrlen(skb)" to compute headers length for a TCP packet, but others use more convoluted (but equivalent) ways. Add skb_tcp_all_headers() and skb_inner_tcp_all_headers() helpers to harmonize this a bit. Signed-off-by:

As stated by Russel King, miic_config() can be called as a result of ethtool setting the configuration while the link is already up. Since the speed is also set in this function, it could potentially modify the current speed that is set. This will only happen if there is no PHY present and we aren't using fixed-link mode. Handle that by storing the current interface mode in the miic_port structure and update the speed only if the interface mode is going to be changed. Signed-off-by:

Vladimir Oltean says: ==================== Prevent permanently closed tc-taprio gates from blocking a Felix DSA switch port Richie Pearn reports that if we install a tc-taprio schedule on a Felix switch port, and that schedule has at least one gate that never opens (for example TC0 below): tc qdisc add dev swp1 root taprio num_tc 8 map 0 1 2 3 4 5 6 7 \ queues 1@0 1@1 1@2 1@3 1@4 1@5 1@6 1@7 \ base-time 0 sched-entry S fe 1000000 flags 0x2 then packets classified to the permanently closed traffic class will not be dequeued by the egress port. They will just remain in the queue system, to consume resources. Frame aging does not trigger either, because in order for that to happen, the packets need to be eligible for egress scheduling in the first place, which they aren't. If that port is allowed to consume the entire shared buffer of the switch (as we configure things by default using devlink-sb), then eventually, by sending enough packets, the entire switch will hang. If we think enough about the problem, we realize that this is only a special case of a more general issue, and can also be reproduced with gates that aren't permanently closed, but are not large enough to send an entire frame. In that sense, a permanently closed gate is simply a case where all frames are oversized. The ENETC has logic to reject transmitted packets that would overrun the time window - see commit 285e8ded ("net: enetc: count the tc-taprio window drops"). The Felix switch has no such thing on a per-packet basis, but it has a register replicated per {egress port, TC} which essentially limits the max MTU. A packet which exceeds the per-port-TC MTU is immediately discarded and therefore will not hang the port anymore (albeit, sadly, this only bumps a generic drop hardware counter and we cannot really infer the reason such as to offer a dedicated counter for these events). This patch set calculates the max MTU per {port, TC} when the tc-taprio config, or link speed, or port-global MTU values change. This solves the larger "gate too small for packet" problem, but also the original issue with the gate permanently closed that was reported by Richie. ==================== Link: https://lore.kernel.org/r/20220628145238.3247853-1-vladimir.oltean@nxp.comSigned-off-by:
