* ramips: allow packets with ttl=0Felix Fietkau2019-03-241-2/+2
| | | | | | | Some broken ISPs (e.g. Comcast) send DHCPv6 packets with hop limit=0. This trips up the TTL=0 check in the PPE if enabled. Signed-off-by: Felix Fietkau <nbd@nbd.name>
* ramips: fix two-way hash and auto ageout on MT7621HsiuWen Yen2019-01-231-17/+18
| | | | | | | | | | | | | | | | | | | | | | | | Current code directly writes the FOE entry to hash_val+1 position when hash collision occurs. However, it is found that this behavior will cause the cache and the hardware FOE table to be inconsistent. For example, there are three flows, and their hashed values are all equal to 100. The first flow is written to the position of 100. The second flow is written to the position of 100+1. Then, the logic of the current code will also write the third flow to 100+1. At this time, the cache has flow 1 and 2; and the hardware FOE table has flow 1 and 3, where these two parts store different contents. So it is necessary to check whether the hash_val+1 is also occupied before writing. If hash_val+1 is also occupied, we won’t bind th third flow to the FOE table. Addition to that, we also cancel the processing of foe_entry removal because the hardware has auto age-out ability. The hardware will periodically iterate through the FOE table to find out the time-out entry and set it as INVALID. Signed-off-by: HsiuWen Yen <y.hsiuwen@gmail.com>

* ramips: add two-way hashing scheme for MT7621HsiuWen Yen2019-01-071-0/+11
| | | | | | | | | | Sometimes the tuples might be hashed to the same FOE entry. When this hash collision problem occurs, some of the connections will not be bound and consequently the CPU idle rate cannot reach 100%. Therefore, two-way hashing is adopted to alleviate this problem. Signed-off-by: HsiuWen Yen <y.hsiuwen@gmail.com>
* ramips: mt7620: add force use of mdio-modePawel Dembicki2018-11-261-0/+3

* ramips: drop obsolete sd card driver codeMathias Kresin2018-09-062-20/+4
| | | | | | | | | | | | | | | | | The pinmux for all SoCs using this driver is now set via the pinmux. It makes this code obsolete. Some of the code targeting the mt76x8 SoCs is still required. The sd card pins share the pads with the EPHY. These pads need to be switched to digital mode if the pins are used for sd cards. The eMMC 8-bit mode has to be enabled via pinmux instead of a kernel option. The uart2 group need to be set to function "sdxc d5 d4", pwm1 to "sdxc d6" and pwm0 to "sdxc d7" to do so. It can't be done by as part of a default pinmux, as it would break the normal operation of uart2. Signed-off-by: Mathias Kresin <dev@kresin.me>
* ramips: ethernet: unify tx descriptor buffer splittingFelix Fietkau2018-09-031-75/+83

| | | | | | | | | | This reverts commit 3a8efaef00d6b7317c46fe6b7e923912d8bf3500. The change reportedly breaks UART2 on some boards. Furthermore it uses bitwise logic on an uninitialized variable and fails to explain what it is fixing exactly. Signed-off-by: Jo-Philipp Wich <jo@mein.io>

* mt7620: gsw: make IntPHY and ExtPHY share mdio addr 4 possibleChen Minqiang2018-08-061-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | To share mdio addr for IntPHY and ExtPHY, as described in the documentation (MT7620_ProgrammingGuide.pdf). (refer: http://download.villagetelco.org/hardware/MT7620/MT7620_ProgrammingGuide.pdf) when port4 setup to work as gmac mode, dts like: &gsw { mediatek,port4 = "gmac"; }; we should set SYSCFG1.GE2_MODE==0x0 (RGMII). but SYSCFG1.GE2_MODE may have been set to 3(RJ-45) by uboot/default so we need to re-set it to 0x0 before this changes: gsw: 4FE + 2GE may not work correctly and MDIO addr 4 cannot be used by ExtPHY after this changes: gsw: 4FE + 2GE works and MDIO addr 4 can be used by ExtPHY Signed-off-by: Chen Minqiang <ptpt52@gmail.com>
* ramips: fix gigabit switch PHY access on MDIODaniel Gimpelevich2018-08-061-1/+2
| | | | | | | | | | When PHY's are defined on the MDIO bus in the DTS, gigabit support was being masked out for no apparent reason, pegging all such ports to 10/100. If gigabit support must be disabled for some reason, there should be a "max-speed" property in the DTS.

* ramips: remove superfluous & confusing DT bindingDaniel Gimpelevich2018-08-061-3/+24
| | | | | | | | | | | Mediatek has a reference platform that pairs an MT7620A with an MT7530W, where the latter responds on MDIO address 0x1f while both chips respond on 0x0 to 0x4. The driver special-cases this arrangement to make sure it's talking to the right chip, but two different ways in two different places. This patch consolidates the detection without the current requirement of both tests to be separately satisfied in the DTS. Signed-off-by: Daniel Gimpelevich <daniel@gimpelevich.san-francisco.ca.us>

* ramips: ethernet: use own page_frag_cacheFelix Fietkau2018-07-122-3/+15
| | | | | | | | | | | | | | | | Using the NAPI or netdev frag cache along with other drivers can lead to 32 KiB pages being held for a long time, despite only being used for very few page fragment. This can happen if the ethernet driver grabs one or two fragments for rx ring refill, while other drivers use (and free up) the remaining fragments. The 32 KiB higher-order page can only be freed once all users have freed their fragments, which only happens after the rings of all drivers holding the fragments have wrapped around. Depending on the traffic patterns, this can waste a lot of memory and look a lot like a memory leak Signed-off-by: Felix Fietkau <nbd@nbd.name>

* ramips: improve ethernet driver performance with GRO/TSOFelix Fietkau2018-06-193-76/+105
| | | | | | | | | | | GRO stores packets as fraglist. If they are routed back to the ethernet device, they need to be re-segmented if the driver does not support sending fraglists. Add the missing support for that, along with a missing feature flag that allows full routed GRO->TSO offload. Considerably reduces CPU utilization for routing Signed-off-by: Felix Fietkau <nbd@nbd.name>

| | | | | | | | | | Since kernel 4.10 commit 61e84623ace3 ("net: centralize net_device min/max MTU checking"), the range of mtu is [min_mtu, max_mtu], which is [68, 1500] by default. It's necessary to set a max_mtu if a mtu > 1500 is supported. Signed-off-by: Mathias Kresin <dev@kresin.me>

The mtk-mmc driver does not support access to highmem pages, so it is really limited to the bottom 512M (actually 448M due to 64M of IO space).
