2020-06-26docs: networking: reorganize driver documentation againJakub Kicinski12-36/+28
Organize driver documentation by device type. Most documents have fairly verbose yet uninformative names, so let users first select a well defined device type, and then search for a particular driver. While at it rename the section from Vendor drivers to Hardware drivers. This seems more accurate, besides people sometimes refer to out-of-tree drivers as vendor drivers.

2020-06-26enetc: Fix tx rings bitmap iteration range, irq handlingClaudiu Manoil1-2/+2
The rings bitmap of an interrupt vector encodes which of the device's rings were assigned to that interrupt vector. Hence the iteration range of the tx rings bitmap (for_each_set_bit()) should be the total number of Tx rings of that netdevice instead of the number of rings assigned to the interrupt vector. Since there are 2 cores, and one interrupt vector for each core, the number of rings asigned to an interrupt vector is half the number of available rings. The impact of this error is that the upper half of the tx rings could still generate interrupts during napi polling.

2020-06-26net: mvneta: speed down the PHY, if WoL used, to save energyDaniel González Cabanelas1-0/+11
Some PHYs connected to this ethernet hardware support the WoL feature. But when WoL is enabled and the machine is powered off, the PHY remains waiting for a magic packet at max speed (i.e. 1Gbps), which is a waste of energy. Slow down the PHY speed before stopping the ethernet if WoL is enabled, and save some energy while the machine is powered off or sleeping.

2020-06-26Merge branch '40GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queueDavid S. Miller53-5784/+243
Jeff Kirsher says: ==================== 40GbE Intel Wired LAN Driver Updates 2020-06-25 This series contains updates to i40e driver and removes the individual driver versions from all of the Intel wired LAN drivers. Shiraz moves the client header so that it can easily be shared between the i40e LAN driver and i40iw RDMA driver. Jesse cleans up the unused defines, since they are just dead weight. Alek reduces the unreasonably long wait time for a PF reset after reboot by using jiffies to limit the maximum wait time for the PF reset to succeed. Added additional logging to let the user know when the driver transitions into recovery mode. Adds new device support for our 5 Gbps NICs. Todd adds a check to see if MFS is set after warm reboot and notifies the user when MFS is set to anything lower than the default value. Arkadiusz fixes a possible race condition, where were holding a spin-lock while in atomic context. v2: removed code comments that were no longer applicable in patch 2 of the series. Also removed 'inline' from patch 4 and patch 8 of the series. Also re-arranged code to be able to remove the forward function declarations. Dropped patch 9 of the series, while the author works on cleaning up the commit message. v3: Updated patch 8 description to answer Jakub's questions ==================== Signed-off-by: David S.

After upgrading to the generic structure, PCI core will take care of required tasks and drivers should do only device-specific operations.

2020-06-25i40e: Remove scheduling while atomic possibilityAleksandr Loktionov1-97/+137
In some occasions task held spinlock (mac_filter_hash_lock), while being rescheduled due to admin queue mutex_lock. The struct i40e_spinlock asq_spinlock, which later expands to struct mutex spinlock. Moved i40e_aq_set_vsi_multicast_promiscuous(), i40e_aq_set_vsi_unicast_promiscuous(), i40e_aq_set_vsi_mc_promisc_on_vlan(), and i40e_aq_set_vsi_uc_promisc_on_vlan() outside of atomic context. Without this patch there is a race condition, which might result in scheduling while in atomic context. The race condition is between the thread, which holds mac_filter_hash_lock, while trying to acquire an admin queue mutex and a thread, which already has said admin queue mutex. The thread, which holds spinlock, fails to acquire the mutex, which causes this thread to sleep.

2020-06-25net/intel: remove driver versions from Intel driversJeff Kirsher39-142/+29
As with other networking drivers, remove the unnecessary driver version from the Intel drivers. The ethtool driver information and module version will then report the kernel version instead. For ixgbe, i40e and ice drivers, the driver passes the driver version to the firmware to confirm that we are up and running. So we now pass the value of UTS_RELEASE to the firmware. This adminq call is required per the HAS document. The Device then sends an indication to the BMC that the PF driver is present. This is done using Host NC Driver Status Indication in NC-SI Get Link command or via the Host Network Controller Driver Status Change AEN. What the BMC may do with this information is implementation-dependent, but this is a standard NC-SI 1.1 command we honor per the HAS.

When a firmware transitions to a recovery mode it stores a number of unexpected EMP resets in one of its registers. The number of EMP resets ranging from 0x21 to 0x2A indicates that FW transitions to recovery mode. Use these values to emit log entry about transition process.

When commit 474ea9cafc45 ("net: bcmgenet: correctly pad short packets") added the call to skb_padto() it should have been located before the nr_frags parameter was read since that value could be changed when padding packets with lengths between 55 and 59 bytes (inclusive). The use of a stale nr_frags value can cause corruption of the pad data when tx-scatter-gather is enabled. This corruption of the pad can cause invalid checksum computation when hardware offload of tx-checksum is also enabled. Since the original reason for the padding was corrected by commit 7dd399130efb ("net: bcmgenet: fix skb_len in bcmgenet_xmit_single()") we can remove the software padding all together and make use of hardware padding of short frames as long as the hardware also always appends the FCS value to the frame.

2020-06-24net: ethernet: mvneta: Do not error out in non serdes modesSascha Hauer1-1/+1
In mvneta_config_interface() the RGMII modes are catched by the default case which is an error return. The RGMII modes are valid modes for the driver, so instead of returning an error add a break statement to return successfully. This avoids this warning for non comphy SoCs which use RGMII, like SolidRun Clearfog: WARNING: CPU: 0 PID: 268 at drivers/net/ethernet/marvell/mvneta.c:3512 mvneta_start_dev+0x220/0x23c Fixes: b4748553f53f ("net: ethernet: mvneta: Fix Serdes configuration for SoCs without comphy") Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Reviewed-by: Russell King <rmk+kernel@armlinux.org.uk> Signed-off-by: David S.

2020-06-23cxgb4: move device dump arrays in header to C fileRahul Lakkireddy4-407/+410
Move all arrays related to device dump in header file to C file. Also, move the function that shares the arrays to the same C file. Fixes following warnings reported by make W=1 in several places: cudbg_entity.h:513:18: warning: 't6_hma_ireg_array' defined but not used [-Wunused-const-variable=] 513 | static const u32 t6_hma_ireg_array[][IREG_NUM_ELEM] = { Fixes: a7975a2f9a79 ("cxgb4: collect register dump") Fixes: 17b332f48074 ("cxgb4: add support to read serial flash") Signed-off-by: Rahul Lakkireddy <rahul.lakkireddy@chelsio.com> Signed-off-by: David S.

2020-06-23cxgb4: always sync access when flashing PHY firmwareRahul Lakkireddy4-17/+10
Access to on-chip memory for flashing PHY firmware must always be synchronized. So, ensure the callers take on-chip memory lock. Also fixes following sparse warning: sge.c:1641:26: warning: context imbalance in 't4_load_phy_fw' - different lock contexts for basic block Fixes: 01b6961410b7 ("cxgb4: Add PHY firmware support for T420-BT cards") Fixes: 4ee339e1e92a ("cxgb4: add support to flash PHY image") Signed-off-by: Rahul Lakkireddy <rahul.lakkireddy@chelsio.com> Signed-off-by: David S.

2020-06-23net/fsl: enable extended scanning in xgmac_mdioJeremy Linton1-0/+1
Since we know the xgmac hardware always has a c45 compliant bus, let's try scanning for c22 capable PHYs first. If we fail to find any, then it will fall back to c45 automatically.
