2019-11-06gianfar: Maximize Rx buffer sizeClaudiu Manoil1-4/+4
Until now the size of a Rx buffer was artificially limited to 1536B (which happens to be the default, after reset, hardware value for a Rx buffer). This approach however leaves unused memory space for Rx packets, since the driver uses a paged allocation scheme that reserves half a page for each Rx skb. There's also the inconvenience that frames around 1536 bytes can get scattered if the limit is slightly exceeded. This limit can be exceeded even for standard MTU of 1500B traffic, for common cases like stacked VLANs, or DSA tags. To address these issues, let's just compute the buffer size starting from the upper limit of 2KB (half a page) and subtract the skb overhead and alignment restrictions.

2019-11-06net: forcedeth: add xmit_more supportZhu Yanjun1-10/+49
This change adds support for xmit_more based on the igb commit 6f19e12f6230 ("igb: flush when in xmit_more mode and under descriptor pressure") and commit 6b16f9ee89b8 ("net: move skb->xmit_more hint to softnet data") that were made to igb to support this feature. The function netif_xmit_stopped is called to check whether transmit queue on device is currently unable to send to determine whether we must write the tail because we can add no further buffers. When normal packets and/or xmit_more packets fill up tx_desc, it is necessary to trigger NIC tx reg. Following the advice from David Miller and Jakub Kicinski, after the xmit_more feature is added, the following scenario will occur. | xmit_more packets | DMA_MAPPING | DMA_MAPPING error check | xmit_more packets already in HW xmit queue | In the above scenario, if DMA_MAPPING error occurrs, the xmit_more packets already in HW xmit queue will also be dropped. This is different from the behavior before xmit_more feature. So it is necessary to trigger NIC HW tx reg in the above scenario. To the non-xmit_more packets, the above scenario will not occur.

2019-11-06netdevsim: drop code duplicated by a mergeJakub Kicinski1-39/+8
Looks like the port adding loop makes a re-appearance on net-next after net was merged back into it (even though it doesn't feature in the merge diff). The ports are already added in nsim_dev_create() so when we try to add them again get EEXIST, and see: netdevsim: probe of netdevsim0 failed with error -17 in the logs. When we remove the loop again the nsim_dev_probe() and nsim_dev_remove() become a wrapper of nsim_dev_create() and nsim_dev_destroy(). Remove this layer of indirection.

Provides additional re-organizing of the code in preparation for adding build_skb() support in the driver. Adjusted the computational padding logic for headroom and tailroom to better support build_skb(), which also aligns with the logic in other Intel LAN drivers.

git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue Jeff Kirsher says: ==================== 10GbE Intel Wired LAN Driver Updates 2019-11-04 This series contains old Halloween candy updates, yet still sweet, to fm10k, ixgbe and i40e. Jake adds the missing initializers for a couple of the TLV attribute macros. Added support for capturing and reporting statistics for all of the VFs in a given PF. Lastly, bump the version of the fm10k driver to reflect the recent changes. Alex addresses locality issues in the ixgbe driver when it is loaded on a system supporting multiple NUMA nodes. Manjunath Patil provides changes to the ixgbe driver, similar to those made to igb, to prevent transmit packets to request a hardware timestamp when the NIC has not been setup via the SIOCSHWTSTAMP ioctl. Alice adds support for x710 by adding the missing device id's in the appropriate places to ensure all the features are enabled in i40e. Jesse adds support for VF stats gathering in the i40e via the kernel via ndo_get_vf_stats function. v2: Fixed up commit id references in patch 5's description to align with how commit id's should be referenced. ==================== Signed-off-by: David S.

2019-11-04i40e: implement VF stats NDOJesse Brandeburg3-0/+51
Implement the VF stats gathering via the kernel via ndo_get_vf_stats(). The driver will show per-VF stats in the output of the command: ip -s link show dev <PF> Testing Hints: ip -s link show dev eth0 will return non-zero VF stats. ... vf 0 MAC 00:55:aa:00:55:aa, spoof checking on, link-state enable, trust off RX: bytes packets mcast bcast 128000 1000 104 104 TX: bytes packets 128000 1000 Signed-off-by: Jesse Brandeburg <jesse.brandeburg@intel.com> Tested-by: Andrew Bowers <andrewx.bowers@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>
2019-11-04i40e: enable X710 supportAlice Michael1-0/+2
The I40E_DEV_ID_10G_BASE_T_BC device id was added previously, but was not enabled in all the appropriate places. Adding it to enable it's use.
