2018-11-18tun: use netdev_alloc_frag() in tun_napi_alloc_frags()Eric Dumazet1-8/+7
In order to cook skbs in the same way than Ethernet drivers, it is probably better to not use GFP_KERNEL, but rather use the GFP_ATOMIC and PFMEMALLOC mechanisms provided by netdev_alloc_frag(). This would allow to use tun driver even in memory stress situations, especially if swap is used over this tun channel.

2018-11-18net: phy: icplus: allow configuring the interrupt function on IP101GRMartin Blumenstingl1-1/+80
The IP101GR is a 32-pin QFN package variant of the IP101G/IP101GA Ethernet PHY. Due to it's limited amount of pins the RXER (receive error) and INTR32 (interrupt) functions share pin 21. By default the PHY is configured to output the "receive error" status on pin 21. Depending on the board layout and requirements we may want to re-configure the PHY to output the interrupt signal there. The mode of pin 21 can be configured in the "Digital I/O Specific Control Register" (register 29), bit 2: - 0 = RXER function - 1 = INTR(32) function Depending on the devicetree configuration we will now: - change the mode to either ther RXER or INTR32 function - keep the SEL_INTR32 value set by the bootloader (default) if no configuration is provided (to ensure that we're not breaking existing boards) - error out if conflicting configuration is given (RXER and INTR32 mode are enabled at the same time) Signed-off-by: Martin Blumenstingl <martin.blumenstingl@googlemail.com> Signed-off-by: David S.

2018-11-18net: phy: icplus: implement .did_interrupt for IP101A/GMartin Blumenstingl1-0/+16
The IP101A_G_IRQ_CONF_STATUS register has bits to detect which interrupts have fired. Implement the .did_interrupt callback to let the PHY core know whether the interrupt was for this specific PHY. This is useful for debugging interrupt problems with 32-pin IP101GR PHYs where the interrupt line is shared with the RX_ERR (receive error status) signal. The default values are: - RX_ERR is enabled by default (LOW means that there is no receive error) - the PHY's interrupt line is configured "active low" by default Without any additional changes there is a flood of interrupts if the RX_ERR/INTR32 signal is configured in RX_ERR mode (which is the default). Having a did_interrupt ensures that the PHY core returns IRQ_NONE instead of endlessly triggering the PHY state machine. Additionally the kernel will report this after a while: irq 28: nobody cared (try booting with the "irqpoll" option) Signed-off-by: Martin Blumenstingl <martin.blumenstingl@googlemail.com> Reviewed-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: David S.

This function will try to determine the mac address via the devicetree, or via an architecture-specific method (e.g. a PROM on SPARC). The SPARC-specific code in this driver (#ifdef SPARC) did exactly this, and is therefore removed.

The manual states that the checksum cannot lie in the last DWORD of the transmission, so add a basic check for this and fall back to software checksumming the packet. This only seems to trigger for ACK packets with no options or data to return to the other end, and the use of the tx-alignment option makes it more likely to happen.

The smsc95xx_tx_fixup is doing multiple calls to skb_push() to put an 8-byte command header onto the packet. It would be easier to do one skb_push() and then copy the data in once the push is done. We also make the code smaller by using proper unaligned puts for the header. This merges in the CPU to LE32 conversion as well and makes the whole sequence easier to understand hopefully.

2018-11-16dpaa2-eth: Don't use multiple queues per channelIoana Ciocoi Radulescu2-2/+3
The DPNI object on which we build a network interface has a certain number of {Rx, Tx, Tx confirmation} frame queues as resources. The default hardware setup offers one queue of each type, as well as one DPCON channel, for each core available in the system. There are however cases where the number of queues is greater than the number of cores or channels. Until now, we configured and used all the frame queues associated with a DPNI, even if it meant assigning multiple queues of one type to the same channel. Update the driver to only use a number of queues equal to the number of channels, ensuring each channel will contain exactly one Rx and one Tx confirmation queue. >From the user viewpoint, this change is completely transparent. Performance wise there is no impact in most scenarios. In case the number of queues is larger than and not a multiple of the number of channels, Rx hash distribution offers now better load balancing between cores, which can have a positive impact on overall system performance.

Using 2.5G speed relies on the SerDes lanes being configured accordingly. The lanes have to be reconfigured to switch between 1G and 2.5G, and for now only the bootloader does this configuration. In the case we add a Comphy driver to handle switching the lanes dynamically, it's better for now to stick with supporting only 1G and add advertisement for 2.5G once we really are capable of handling both speeds without problem. Since the interface mode is initialy taken from the DT, we want to make sure that adding comphy support won't break boards that don't update their dtb.

2018-11-15net/mlx4_core: Zero out lkey field in SW2HW_MPT fw commandJack Morgenstein1-0/+1
When re-registering a user mr, the mpt information for the existing mr when running SRIOV is obtained via the QUERY_MPT fw command. The returned information includes the mpt's lkey. This retrieved mpt information is used to move the mpt back to hardware ownership in the rereg flow (via the SW2HW_MPT fw command when running SRIOV). The fw API spec states that for SW2HW_MPT, the lkey field must be zero. Any ConnectX-3 PF driver which checks for strict spec adherence will return failure for SW2HW_MPT if the lkey field is not zero (although the fw in practice ignores this field for SW2HW_MPT). Thus, in order to conform to the fw API spec, set the lkey field to zero before invoking SW2HW_MPT when running SRIOV.

2018-11-15Merge branch '40GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queueDavid S. Miller11-43/+116
Jeff Kirsher says: ==================== 40GbE Intel Wired LAN Driver Updates 2018-11-14 This series contains updates to i40e and virtchnl. Lance Roy updates i40e to use lockdep_assert_held() instead of spin_is_locked(), since it is better suited to check locking requirements. Jan improves the code readability in XDP by adding the use of a local variable. Provides protection on methods that create/modify/destroy VF's via locking mechanism to prevent unstable behaviour and potential kernel panics. Krzysztof adds a hardware capability flag to indicate whether firmware supports stopping the LLDP agent. Patryk replaces the use of strncpy() with strlcpy() to ensure the buffer is NULL terminated. Mitch fixes the issue of trying to start nway on devices that do not support auto-negotiation, by checking the autoneg state before attempting to restart nway. Alice updates virtchnl to keep the checks all together for ease of readability and consistency. Also fixed a "off by one" error in the number of traffic classes being calculated. Richard fixed VF port VLANs, where the priority bits were incorrectly set because the incorrect shift and mask bits were being used. Alan adds a bit to set and check if a timeout recovery is already pending to prevent overlapping transmit timeout recovery. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

2018-11-15mlxsw: spectrum: acl: Pass key pointer to master_mask_set/clearJiri Pirko1-13/+17
The device requires that the master mask of each region will be composed from a logical OR between all the unmasked bits in the region. Currently, this is just a logical OR between all the eRPs used in the region, but the next patch is going to introduce delta bits support which need to be taken into account as well. Since the eRP does not include the delta bits, pass the key pointer to mlxsw_sp_acl_erp_master_mask_set/clear instead. Convert key->mask to the bitmap on fly.
