2022-07-21net: ftgmac100: Hold reference returned by of_get_child_by_name()Liang He1-1/+14
[ Upstream commit 49b9f431ff0d845a36be0b3ede35ec324f2e5fee ] In ftgmac100_probe(), we should hold the refernece returned by of_get_child_by_name() and use it to call of_node_put() for reference balance.

2022-06-06net: ftgmac100: Disable hardware checksum on AST2600Joel Stanley1-0/+5
[ Upstream commit 6fd45e79e8b93b8d22fb8fe22c32fbad7e9190bd ] The AST2600 when using the i210 NIC over NC-SI has been observed to produce incorrect checksum results with specific MTU values. This was first observed when sending data across a long distance set of networks. On a local network, the following test was performed using a 1MB file of random data. On the receiver run this script: #!/bin/bash while [ 1 ]; do # Zero the stats nstat -r > /dev/null nc -l 9899 > test-file # Check for checksum errors TcpInCsumErrors=$(nstat | grep TcpInCsumErrors) if [ -z "$TcpInCsumErrors" ]; then echo No TcpInCsumErrors else echo TcpInCsumErrors = $TcpInCsumErrors fi done On an AST2600 system: # nc <IP of receiver host> 9899 < test-file The test was repeated with various MTU values: # ip link set mtu 1410 dev eth0 The observed results: 1500 - good 1434 - bad 1400 - good 1410 - bad 1420 - good The test was repeated after disabling tx checksumming: # ethtool -K eth0 tx-checksumming off And all MTU values tested resulted in transfers without error. An issue with the driver cannot be ruled out, however there has been no bug discovered so far. David has done the work to take the original bug report of slow data transfer between long distance connections and triaged it down to this test case. The vendor suspects this this is a hardware issue when using NC-SI. The fixes line refers to the patch that introduced AST2600 support.

2022-04-20net: ftgmac100: access hardware register after clock readyDylan Hung1-5/+5
[ Upstream commit 3d2504524531990b32a0629cc984db44f399d161 ] AST2600 MAC register 0x58 is writable only when the MAC clock is enabled. Usually, the MAC clock is enabled by the bootloader so register 0x58 is set normally when the bootloader is involved. To make ast2600 ftgmac100 work without the bootloader, postpone the register write until the clock is ready.

2021-07-27dev_ioctl: split out ndo_eth_ioctlArnd Bergmann2-2/+2
Most users of ndo_do_ioctl are ethernet drivers that implement the MII commands SIOCGMIIPHY/SIOCGMIIREG/SIOCSMIIREG, or hardware timestamping with SIOCSHWTSTAMP/SIOCGHWTSTAMP. Separate these from the few drivers that use ndo_do_ioctl to implement SIOCBOND, SIOCBR and SIOCWANDEV commands. This is a purely cosmetic change intended to help readers find their way through the implementation.

2019-11-04net: of_get_phy_mode: Change API to solve int/unit warningsAndrew Lunn1-3/+3
Before this change of_get_phy_mode() returned an enum, phy_interface_t. On error, -ENODEV etc, is returned. If the result of the function is stored in a variable of type phy_interface_t, and the compiler has decided to represent this as an unsigned int, comparision with -ENODEV etc, is a signed vs unsigned comparision. Fix this problem by changing the API. Make the function return an error, or 0 on success, and pass a pointer, of type phy_interface_t, where the phy mode should be stored. v2: Return with *interface set to PHY_INTERFACE_MODE_NA on error. Add error checks to all users of of_get_phy_mode() Fixup a few reverse christmas tree errors Fixup a few slightly malformed reverse christmas trees v3: Fix 0-day reported errors.

2019-10-29net: ethernet: ftgmac100: Fix DMA coherency issue with SW checksumBenjamin Herrenschmidt1-13/+12
We are calling the checksum helper after the dma_map_single() call to map the packet. This is incorrect as the checksumming code will touch the packet from the CPU. This means the cache won't be properly flushes (or the bounce buffering will leave us with the unmodified packet to DMA). This moves the calculation of the checksum & vlan tags to before the DMA mapping. This also has the side effect of fixing another bug: If the checksum helper fails, we goto "drop" to drop the packet, which will not unmap the DMA mapping.

2019-08-03net: ftgmac100: Add support for DT phy-handle propertyAndrew Jeffery1-4/+33
phy-handle is necessary for the AST2600 which separates the MDIO controllers from the MAC. I've tried to minimise the intrusion of supporting the AST2600 to the FTGMAC100 by leaving in place the existing MDIO support for the embedded MDIO interface. The AST2400 and AST2500 continue to be supported this way, as it avoids breaking/reworking existing devicetrees. The AST2600 support by contrast requires the presence of the phy-handle property in the MAC devicetree node to specify the appropriate PHY to associate with the MAC. In the event that someone wants to specify the MDIO bus topology under the MAC node on an AST2400 or AST2500, the current auto-probe approach is done conditional on the absence of an "mdio" child node of the MAC.

2018-11-22net: faraday: ftmac100: remove netif_running(netdev) check before disabling ↵Vincent Chen1-4/+3
interrupts In the original ftmac100_interrupt(), the interrupts are only disabled when the condition "netif_running(netdev)" is true. However, this condition causes kerenl hang in the following case. When the user requests to disable the network device, kernel will clear the bit __LINK_STATE_START from the dev->state and then call the driver's ndo_stop function. Network device interrupts are not blocked during this process. If an interrupt occurs between clearing __LINK_STATE_START and stopping network device, kernel cannot disable the interrupts due to the condition "netif_running(netdev)" in the ISR. Hence, kernel will hang due to the continuous interruption of the network device. In order to solve the above problem, the interrupts of the network device should always be disabled in the ISR without being restricted by the condition "netif_running(netdev)".

2017-10-18net: ftgmac100: Request clock and set speedJoel Stanley1-0/+26
According to the ASPEED datasheet, gigabit speeds require a clock of 100MHz or higher. Other speeds require 25MHz or higher. This patch configures a 100MHz clock if the system has a direct-attached PHY, or 25MHz if the system is running NC-SI which is limited to 100MHz. There appear to be no other upstream users of the FTGMAC100 driver it is hard to know the clocking requirements of other platforms. Therefore a conservative approach was taken with enabling clocks. If the platform is not ASPEED, both requesting the clock and configuring the speed is skipped.
