As Arnd Bergmann pointed out in commit 78fe8a28 ("net: dsa: sja1105: fix ptp link error"), there is no point in having PTP support as a separate loadable kernel module. So remove the exported symbols and make sja1105.ko contain PTP support or not based on CONFIG_NET_DSA_SJA1105_PTP. Signed-off-by:

Regmap provides bit manipulation functions to set/clear bits, use those insted of reimplementing them. Signed-off-by:

Marek Vasut authored
The regmap config tables are rather similar for various generations of the KSZ8xxx/KSZ9xxx switches. Introduce a macro which allows generating those tables without duplication. Note that $regalign parameter is not used right now, but will be used in KSZ87xx series switches. Signed-off-by:

Since the driver now uses regmap , get rid of ad-hoc ksz_io_ops abstraction, which no longer has any meaning. Moreover, since regmap has it's own locking, get rid of the register access mutex. Signed-off-by:

Marek Vasut authored
Add basic SPI regmap support into the driver. Previous patches unconver that ksz_spi_write() is always ever called with len = 1, 2 or 4. We can thus drop the if (len > SPI_TX_BUF_LEN) check and we can also drop the allocation of the txbuf which is part of the driver data and wastes 256 bytes for no reason. Regmap covers the whole thing now. Signed-off-by:

The indirect function call to dev->dev_ops->get_port_addr() is expensive especially if called for every single register access, and only returns the value of PORT_CTRL_ADDR() macro. Use PORT_CTRL_ADDR() macro directly instead. Signed-off-by:

These functions are only used by the KSZ9477 code, move them from the header into that code. Note that these functions will be soon replaced by regmap equivalents. Signed-off-by:

Marek Vasut authored
The functions in the header file are static, and the header file is included from single C file, just inline the code into the C file. The bonus is that it's easier to spot further content to clean up. Signed-off-by:

Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2019-06-26 This series contains updates to ixgbe and i40e only. Mauro S. M. Rodrigues update the ixgbe driver to handle transceivers who comply with SFF-8472 but do not implement the Digital Diagnostic Monitoring (DOM) interface. Update the driver to check the necessary bits to see if DOM is implemented before trying to read the additional 256 bytes in the EEPROM for DOM data. Young Xiao fixes a potential divide by zero issue in ixgbe driver. Aleksandr fixes i40e to recognize 2.5 and 5.0 GbE link speeds so that it is not reported as "Unknown bps". Fixes the driver to read the firmware LLDP agent status during DCB initialization, and to properly log the LLDP agent status to help with debugging when DCB fails to initialize. Martyna fixes i40e for the missing supported and advertised link modes information in ethtool. Jake fixes a function header comment that was incorrect for a PTP function in i40e. Maciej fixes an issue for i40e when a XDP program is loaded the descriptor count gets reset to the default value, resolve the issue by making the current descriptor count persistent across resets. Alice corrects a copyright date which she found to be incorrect. Piotr adds a log entry when the traffic class 0 is added or deleted, which was not being logged previously. Gustavo A. R. Silva updates i40e to use struct_size() where possible. ==================== Signed-off-by: -

Julian Wiedmann says: ==================== s390/qeth: updates 2019-06-27 please apply another round of qeth updates for net-next. This completes the conversion of the control path to use dynamically allocated cmd buffers, along with some fine-tuning for the route validation fix that recently went into -net. ==================== Signed-off-by: -

The cast type currently gets selected in .ndo_start_xmit, and is then piped through several layers until it's stored into the HW header. Push the selection down into qeth_l?_fill_header() to (1) reduce the number of xmit-wide parameters, and (2) merge the two route validation checks into just one. Signed-off-by:

Use napi_gro_receive() to pass up all types of packets that a L3 device may receive. 1) For proper L2 packets received by the IQD sniffer, this is the obvious thing to do. 2) For af_iucv (which doesn't provide a GRO assist), the GRO code will transparently fall back to netif_receive_skb(). So there's no need to special-case this traffic in our code. Signed-off-by:

Apply some cleanups to qeth_snmp_command() and its callback: 1. when accessing the user data, use the proper struct instead of hard-coded offsets. Also copy the request data straight into the allocated cmd, skipping the extra memdup_user() to a tmp buffer. 2. capping the request length is no longer needed, the same check gets applied at a base level in qeth_alloc_cmd(). 3. clean up some duplicated (and misindented) trace statements.

Now that all cmds are dynamically allocated, the code for static cmd buffers can go away entirely. Resulting in a nice reduction of code/data size & complexity, while removing the risk that qeth_clear_cmd_buffers() releases cmds that are still in-flight. Signed-off-by:

Julian Wiedmann authored
The base MPC cmds are the last remaining user of the static cmd buffers. Port them over to use dynamic allocation, and stop backing the write channel's cmd buffers with pages. Signed-off-by:
-
Julian Wiedmann authored
The VNICC code is somewhat quirky in that it defers the whole cmd setup to a common helper qeth_l2_vnicc_request(). Some of the cmd specifics are then passed in via parameter, while others are simply hard-coded. Split the whole machinery up into the usual format: one helper that allocates the cmd & fills in the common fields, while all the cmd originators take care of their sub-cmd type specific work. This makes it much easier to calculate the cmd's precise length, and reduces code complexity. Signed-off-by:

Julian Wiedmann authored
This patch converts the adapter, assist and bridgeport cmd paths to dynamic allocation. Most of the work is about re-organizing the cmd headers, calculating the correct cmd length, and filling in the right value in the sub-cmd's length field. Since we now also set the correct length for cmds that are not reflected by a fixed struct (ie SNMP), we can remove the work-around from qeth_snmp_command(). Signed-off-by:

For code that uses qeth_send_simple_setassparms_prot(), we currently can't differentiate whether the cmd should contain (1) no parameter, or (2) a 4-byte parameter with value 0. At the moment this doesn't cause any trouble. But when using dynamically allocated cmds, we need to know whether to allocate & transmit an additional 4 bytes of zeroes. So instead of the raw parameter value, pass a parameter pointer (or NULL) to qeth_send_simple_setassparms_prot(). Signed-off-by:

This patch reduces the usage of the write channel's static cmd buffers, by dynamically allocating all simple IPA cmds (eg. STARTLAN, SETVMAC). It also converts the OSN path. Doing so requires some changes to how we calculate the cmd length. Currently when building IPA cmds, we're quite generous in how much data we send down to the device (basically the size of the biggest cmd we know). This is no real concern at the moment, since the static cmd buffers are backed with zeroed pages. But for dynamic allocations, the exact length matters. So this patch also adds the needed length calculations to each cmd path. Commands that have multiple subtypes (eg. SETADP) of differing length will be converted with follow-up patches. Signed-off-by:

Florian Westphal says: ==================== net: ipv4: fix circular-list infinite loop Tariq and Ran reported a regression caused by net-next commit 2638eb8b ("net: ipv4: provide __rcu annotation for ifa_list"). This happens when net.ipv4.conf.$dev.promote_secondaries sysctl is enabled -- we can arrange for ifa->next to point at ifa, so next process that tries to walk the list loops forever. Fix this and extend rtnetlink.sh with a small test case for this. ==================== Signed-off-by:

This exercises the 'promote_secondaries' code path. Without previous fix, this triggers infinite loop/soft lockup: ifconfig process spinning at 100%, never to return. Signed-off-by:

secondary address promotion causes infinite loop -- it arranges for ifa->ifa_next to point back to itself. Problem is that 'prev_prom' and 'last_prim' might point at the same entry, so 'last_sec' pointer must be obtained after prev_prom->next update.

When parsing an ethtool_rx_flow_spec, users can specify an ethernet flow which could contain matches based on the ethernet header, such as the MAC address, the VLAN tag or the ethertype. ETHER_FLOW uses the src and dst ethernet addresses, along with the ethertype as keys. Matches based on the vlan tag are also possible, but they are specified using the special FLOW_EXT flag.
